ZWICKAU (SAXONY), GERMANY- A cold afternoon lingers over the Ore Mountains, the fingers tingling and icy cold, yet the brave soul prevails as he crosses a historic landmark for the first time in almost a year. The Röhrensteg, a 1500s-era covered bridge spanning the Zwickau Mulde on the south end of Zwickau is now open to traffic. After seven months of being closed due to a massive makeover, the bridge now provides access to Reinsdorf and all points east after pedestrians and cyclists were forced to take a detour either via the Schedewitz Bridges to the southwest or the Paradiesbrücke to the northeast.

While scaffolding is still on the bridge due to some minor cosmetic work done on the bridge, one will have a chance to take a look at what changes were done to the bridge, both up close and personal, as well as from a distance. To find out how much work was done, I’ve created an activity for the readers to compare and discuss. Have a look at the Röhrensteg in its original form when it was filmed and photographed in 2016 and compare it to the film I produced on the day of its posting, as well as the photos and answer the following questions:

1. What is different in the bridge after its rehabilitation in terms of its sturcture and design, both inside and out?

2. What was left as is?

3. What could be worked on further?

4. How satisfied are you with the reconstruction? With this question, I have a poll for you to grade on.

 

Have a look and feel free to comment as well.  🙂

Cainsdorf Bridge south of Zwickau: Future as a Pedestrian Bridge?

As the year is slowly but surely coming to a close, we’re starting to see some developments in Saxony, pertaining to the bridges; especially along the Zwickau Mulde as it had been a work zone for much of the year but . Some are good, but others just want to make a person scratch his head. In either case, this Newsflyer focuses on the bridges in the region, most of them are updates.

New Arches for the Hirschgrund

GLAUCHAU- Four months after razing all but two of the outer arches of the Hirschgrund Bridge at the Castle Complex in Glauchau, the bridge is being rebuilt, bit-by-bit. According to observations made by the Chronicles on Buß und Bettag (The Day of Prayer and Reflection), four new arches have been installed, thus reestablishing connection between the south entrance to the castle and the park across from the ravine. The arches have a red lining as they are made of brick, thus making it one of the first signs that the bridge will have a different face come time of its reopening in the Fall 2019. The next part is building up the spandrel to make the crossing more even. Chances are though that due to wintry conditions to come, the reconstruction will commence in the spring.

Almost Done with the Röhrensteg

ZWICKAU- Work is almost finished with the Röhrensteg, a 500-year old covered bridge spanning the Zwickau Mulde. Work started dismantling and repairing bridge parts in May, yet the project was delayed substantially because of the delay in the shipment of a special wood that was used to build the covered bridge. Furthermore, many parts needed to be replaced because they no longer could be used due to age, wear and tear and as a result, cracks and other creases that developed. The pedestrian bridge is scheduled to be reopened by year’s end. However, based on observations, the structure will look totally different than it had been in the years before the much-needed makeover. How different? An article will be produced and one can see the difference for himself.

 

Going Up in Schlunzig

SCHLUNZIG/GLAUCHAU/ZWICKAU- When travelling north on Highway B-93 from Zwickau to Meerane, one can see from the distance at the Mosel exit a tower that is growing by the day. That is because the Schlunzig Cable-Stayed Bridge and its tower is being put together bit-by-bit. Already, two 21-ton pylons, measured at 8 meters tall and 3.1 meters wide were hoisted onto the concrete tower by crane and fastened together, thus creating an H-shaped pattern. From there, 24 cables measuring between 28 and 55 meters will be hung and stiffened from the 32-meter high pylon, which will support the roadway. The deck will be built in segments beginning next year. The 7 million Euro bridge over the Zwickau Mulde will replace the concrete beam bridge dating back to 1964 that is still open, allowing drivers to see the new bridge. That bridge, which suffered irreparable damage due to the 2013 floods, will be removed once the bridge opens in the Summer 2019.

 

Cainsdorf Bridge as a Pedestrian Bridge?

CAINSDORF/ ZWICKAU- Another hot debate on the horizon is with the Cainsdorf Bridge. Located six kilometers upstream, the 1929 deck plate girder bridge has reached the end of its useful life and construction is planned to build a new bridge. The question is whether it should be 300 meters to the north of the bridge, reported earlier in the year or whether it should be at the same spot as the present structure, whose weight limit of 3 tons has reduced access to just cars. Both options have been met with opposition because of the disadvantages. Opponents for the first option claim that having two bridges would mean a waste of money. Even talks of restoring the bridge for pedestrian and bike use instead of for cars are being met with hefty criticism for that key reason. By the same token tearing down the bridge and rebuilding on the spot will cut off key access between Reinsdorf (and other areas to the east) and the southern suburbs of Zwickau (especially the Planitz area), especially as there is a high school, churches and housing nearby. This would be an inconvenience to the residents as well. The debate between convenience/logistics versus money will continue to be a hot topic as the city council will be discussing this before reaching a decision come the end of this year. By that time, one will take advantage at the expense of the other.

 

Stone Arch Bridge to be rehabilitated in 2020?

LUNZENAU- The forms have been filled and sent. Talks have concluded. Yet no action has been taken. Why? This is the issue facing the residents of Lunzenau and the future of its bridge. The Stone Arch Bridge spans the Zwickau Mulde and was built in 1863 replacing a covered bridge that dated back to the 13th Century. It was rebuilt after the floods in 1954 and a temporary bridge was built over the original decking in 2011. The bridge is now going to be rebuilt, bringing its original charm back to the community, but work will not start before 2020. Reason: A temporary bridge is needed to allow for traffic to pass while the arch bridge is being restored. The cost for that alone is EUR 770,000 of the 2 million that is needed for rebuilding it. That needs an extra approval. The temp bridge is needed for the next crossing is eight kilometers away in Göhren for cars. For pedestrians, the Küblers Bridge is two kilometers away from the town center. It is concluded that the arch bridge needs to be restored. Once the approval is received, work can start next Fall.

Bridgehunter Online Shop now open

ZWICKAU/ GLAUCHAU/ AUE- The Bridgehunter’s Chronicles now has an online shop, opened just in time for the holiday season. For the first time since 2015, the Chronicles is selling products pertaining to historic bridges in the US, Europe and elsewhere. While there are no calendars for sale for 2019 (it is being planned for 2020, though), the shop’s main features include the bridges along the Zwickau Mulde River and its cities, Glauchau and Zwickau, which can be found in the apparel. The images produced by the author are based on a questionnaire that was conducted in August 2018, where voters were to decide which of the 40 bridges along the river should be on the T-shirt. In the end, it was decided that three different designs were to be made. A fourth one on the bridges in the Lunzenau region is being considered should the sale be a success. There are also other items with photos and designs on there where a person can purchase for use, including Christmas cards. Click onto the link below, feel free to shop around, and if you find the right gift for that particular person, feel free to order online. More products will come later, so stop by every often.

2016 Author’s Choice Awards

Wagon Wheel Bridge in Boone. Photo taken in September 2010 when the bridge was closed to all traffic. It was torn down in 2016 after the western half of the structure collapsed.

While voters are scrambling to cast their last-minute ballots for the 2016 Ammann Awards by the Bridgehunter’s Chronicles, we have a wide array of bridges that received the Author’s Choice Awards. The awards are based on the author’s selection of bridge stories that were either the most talked about or the most unique, pending on the categories here. What is even interesting about this year’s awards is that they are being given on the eve of Donald Trump taking office as the next President of the US on January 20th. As he promised to spend billions on improving infrastructure, he has no clue as to how to allocate these funds properly, let alone specify , how these new bridges are to be built, I decided to pose a challenge to him on that to see if he’s paying attention to the needs of Americans in his quest to “make America great again.” You will see that in one of the categories…..

So without further ado, let’s have a look at the winners of these awards and their runners up…..

Most Spectacular Disaster:

US-

Wagon Wheel Bridge in Iowa

The Wagon Wheel Bridge is the tragedy story of 2016, but started in September 2015. We had an arsonist set fire to the planks which set the motion for its demise. In February 2016, floating chunks of ice in the Des Moines River rammed the western half of the bridge, tilting the already tilting cylindrical steel piers even further and creating an “S” shape in the structure. The last nail in the coffin was the collapse of one of the middle spans in March. While a pair of eyewitnesses saw the event live while fishing, neither of them were hurt.  The wrecked span and the westernmost span were removed in June, but not before saving a pair of planks awaiting display at a local historical society in Minnesota. The rest of the spans- including the longest of the 730-foot bridge- were removed shortly before Christmas.   The Wagon Wheel Bridge represented a tragedy in two parts: There was tragedy because of Mother Nature and there was tragedy because of years of neglect. While Boone County was relieved of its liability, its next step is to preserve its legacy in a form of a memorial or exhibit. That has yet to be seen.

Runner-up-

Tappan Zee Bridge in New York

During work on the replacement of the 1952 cantilever truss span over the Hudson River at Tarrytown, a crane located at one of the towers of the new bridge collapsed, falling onto the old structure, stopping all traffic in both directions for hours. No casualties were reported, but one of the propane truck drivers travelling eastbound barely missed the crane by feet! Luckily, the old structure, which is scheduled to be demolished in 2018 after the new bridge is open to traffic, sustained no damage to the super structure but minor damage to the railings on the deck the crane fell. The cause of the collapse was high winds. It was a close call and one that brings up the question of strength and effectiveness of truss bridges as they appear to be gaining favor over cable-stayed and modern beam bridges, for many reasons.

International- 

Suspension Bridge in Bali:

We had several bridge disasters on the international scale this year. The Lembogan-Ceningan Bridge was the worst of them. Built in the 1980s, this suspension bridge collapsed under a weight of pedestrians and motorcyclists who were participating in a Hindu ceremony on October 16th. Nine people were killed and scores of others were injured. The cause of the collapse was a combination of too many people, which exceeded the weight limit, and design flaws. The collapse rekindled two disasters that we’ll be commemorating this year: The 50th anniversary of the Silver Bridge collapse over the Ohio River and the 10th anniversary of the I-35 Bridge in Minneapolis. Both bridges had design flaws that caused their failures respectively.

Runner-up-

Mahad Bridge in Mumbai, India:

India had two major bridge failures in 2016- the Kolkatta Flyover which killed 23 people and this one, spanning the Savitri River between Mumbai and the State of Goa. This one was far worse, as the stone arch and steel structure that dated back to Colonial British rule collapsed under the pressure of floodwaters, taking with it two busses full of passengers. Nine lives were lost including one of the two bus drivers. Dozens were injured and at least 20 had been reported missing. The bridge collapse combined natural disasters with inadequate bridge design and lack of maintenance, both of which were brought up to the national government afterwards.

Biggest Bonehead Story:

US-

Broadway Bridge in Little Rock:

How many attempts does a person need to demolish a bridge? For the Hennepin Avenue Bridge in Minneapolis, one needed three to bring down a steel arch bridge in 1987 in favor of the current suspension bridge. That bridge was 100 years old at the time of its demise. For the Broadway Bridge in Little Rock, Arkansas, a multiple span arch bridge featuring a 1974 tied arch main span plus multiple span concrete closed spandrel arch approaches built in 1893, one needed EIGHT attempts! Very lame attempts to not only justify the bridge’s weaknesses prior to the demolition by government officials, but also in demolishing the structure through implosions. The bridge was finally brought down with the crane for the eighth and final time. Yet the epic failures did raise a question of whether the bridge was THAT functionally obsolete and whether the new tied arch bridge will survive as long as the downed span. I don’t think so…..

Runner-up-

Two-Mile Creek Bridge near Hatfield, AK:

2016 started off with the demolition of this through truss bridge over Two-Mile Creek, the last of its kind in Polk County, by an oversized truck with trailer!!! The bridge was replaced in quick time, being opened by November! Thanks, dude for your ignorance!

International-

Chemnitz Viaduct in Germany:

As part of the plan to modernize the rail track between Kassel (Hesse) and Chemnitz (Saxony) via Erfurt, Jena and Glauchau, the German Railways are trying to replace a 120+ year old historic bridge that is perfectly in good enough form to last another 120 years. Its replacement proposal: An open spandrel steel arch bridge with very little aesthetic value. Good thing the people in Chemnitz are speaking out against that proposal and for restoring one of only a handful of pre-1939 landmarks in Chemnitz. But will their voices be heard? Die Bahn macht man mobil!

Runner-up-

Eisenbahnviadukt in Linz, Austria:

Linz’s mayor Klaus Luger had it his way when he campaigned for the 1912 three span bridge spanning the Danube River to be demolished and 70% of the Linz community voted for it. However, haste made waste when one of the three spans, removed from the river and on a hydraulic lift, collapsed! That span was to be reused as part of an a plan for a park. This put the last nails in the coffin regarding any chance of saving the bridge’s legacy. Luger must’ve really hated the bridge enough to see it to a recycling complex.

Best Use of a Restored Historic Bridge-

Molly’s Landing Bridges along Historic US 66:

While the historic bridges in Oklahoma are dwindling rapidly every year, a successful attempt was made to relocate one of the twins of the Bird Creek Bridge. Slated for demolition in 2012, Russ White, owner of Molly’s Landing found a creative way of saving the 1936 spans for their complex near the Verdigris. This led to Roger’s Landing to take the remaining spans of the bridge some time later. While the Bird Creek Bridges are no longer on Route 66, one can see them on display not far apart from each other.

Runner Up:

The Bridge at Strawtown Koteewi Park and White River Campground in Hamilton County, Indiana.

This was almost a toss-up between this bridge and Molly’s Landing. But the bridge in Hamilton County definitely deserved at least runner-up of this award because engineers and park officials managed to import three historic bridges from three different counties to form a 285-foot long super span, featuring a Pratt through truss, a Whipple through truss and a rebuilt deck girder span connecting the two spans! Indiana has been well-known for restoring and reusing historic bridges, yet this one takes bridge preservation to new levels.

Worst example of reusing a Historic Bridge:

B.B. Comer Bridge in Alabama: The multi-span cantilever through truss bridge was demolished earlier this year, after officials in Alabama rejected a proposal to even talk about preserving the 1930 span. As compensation, ALDOT offered one of the bridge’s portal bracings to be erected at a park near the bridge. If this was compensation or a strategy to save Governor Bentley’s “legacy” in the face of scandals he was facing at that time, here a simple Denglish term to keep in mind: “Ziemlich Lame!”and “Opfer eines F**k- ups!”

Best Find of a Historic Bridge-

US-

Bridge to Nowhere in San Gabriel Mountains (California):

California is well known for its multiple-span concrete open spandrel arch bridges, especially along Highway 101. However, this bridge, located near Azusa, can only be accessed by foot! Built in 1936, the bridge was abandoned after a mudslide blocked the key highway between San Gabriel Valley and Wrightwood in March 1938. Today, the bridge can be reached by foot, although it is seen as a liability because of a high rate of fatalities. The US Forest Service owns the bridge and has been working together with local groups on how to minimize it. Nevertheless, the bridge has a unique background worth seeing.

International-

The Bridges of Glauchau (Saxony), Germany:

The author visited this community in the summer 2016 and was quite impressed with its bridges. While the town is located along the Zwickauer Mulde, which is laden with modern bridges, most of the arch bridges dating back to the 1800s and earlier are located either along the railroad line, or on the hill spanning gulches and moats at or near the city’s two castles. Very atypical for a city in a river valley, where normal historic bridges would be located.

Röhrensteg in Zwickau (Saxony), Germany

Röhrensteg in Zwickau, Germany:

The Bridge of Pipes is the oldest of Zwickau’s bridges. It is also the most unique because of its design and function. It has two different truss spans- one per side- two different portal bracings and until 70 years ago, used to transport water over the river from Reinsdorf to Zwickau’s city center using wooden pipes! This was one multi-functional bridge and despite getting a much-needed facelift, one of the key landmarks people should see while in Zwickau.

Russia’s bridges:

With that, I have a “Denkzettel” for Donald Trump with regards to another runner-up, the bridges of Russia, according to the magazine Russia Today. The author there found some very unique and fancy bridges- some rolling back bridge types that had been scrutinized by many bridge engineers and politicians and some that are pure eye-openers. Donald Trump vowed to invest billions of dollars in funding to improve the infrastructure and build great bridges. How can he do that? He should use the playbook of the bridge types that have been rendered useless in the past but are being used in other countries. That means if he wants to make America great again, he needs some signature structures like the Bollmann Bridge in Savage, MD, The Hulton Bridge near Pittsburgh and even the arch bridges along California’s coast. If he continues the policies of building cable-stayed bridges, like the Kit Carson Bridge in Kansas City or the Fort Steuben Bridge near Wheeling, WV, he will make America blander and more boring than it is right now. So Mr. Trump, I challenge you to make America Great by not only preserving our American heritage and history but also build your fancy bridges that we want to see for generations to come. Put the Twitter down and get to work. Any ugliness on the landscape and we will make sure these eyesores are gone at the same time as you are, which will be much quicker than you think. If Russia and China can do it and the Europeans can preserve their past heritage, so can the United States of America, the Republic to which it stands, one nation, under God and under several prophets from Jesus Christ to Muhammad to Siddartha Buddha, indivisible, with liberty, justice and equality to all, regardless of preference.

And now to the Ammann Award results………

The Bridges of Glauchau (Saxony), Germany:

The author visited this community in the summer 2016 and was quite impressed with its bridges. While the town is located along the Zwickauer Mulde, which is laden with modern bridges, most of the arch bridges dating back to the 1800s and earlier are located either along the railroad line, or on the hill spanning gulches and moats at or near the city’s two castles. Very atypical for a city in a river valley, where normal historic bridges would be located.

Röhrensteg in Zwickau (Saxony), Germany

Röhrensteg in Zwickau, Germany:

The Bridge of Pipes is the oldest of Zwickau’s bridges. It is also the most unique because of its design and function. It has two different truss spans- one per side- two different portal bracings and until 70 years ago, used to transport water over the river from Reinsdorf to Zwickau’s city center using wooden pipes! This was one multi-functional bridge and despite getting a much-needed facelift, one of the key landmarks people should see while in Zwickau.

 

Russia’s bridges:

With that, I have a “Denkzettel” for Donald Trump with regards to another runner-up, the bridges of Russia, according to the magazine Russia Today. The author there found some very unique and fancy bridges- some rolling back bridge types that had been scrutinized by many bridge engineers and politicians and some that are pure eye-openers. Donald Trump vowed to invest billions of dollars in funding to improve the infrastructure and build great bridges. How can he do that? He should use the playbook of the bridge types that have been rendered useless in the past but are being used in other countries. That means if he wants to make America great again, he needs some signature structures like the Bollmann Bridge in Savage, MD, The Hulton Bridge near Pittsburgh and even the arch bridges along California’s coast. If he continues the policies of building cable-stayed bridges, like the Kit Carson Bridge in Kansas City or the Fort Steuben Bridge near Wheeling, WV, he will make America blander and more boring than it is right now. So Mr. Trump, I challenge you to make America Great by not only preserving our American heritage and history but also build your fancy bridges that we want to see for generations to come. Put the Twitter down and get to work. Any ugliness on the landscape and we will make sure these eyesores are gone at the same time as you are, which will be much quicker than you think. If Russia and China can do it and the Europeans can preserve their past heritage, so can the United States of America, the Republic to which it stands, one nation, under God and under several prophets from Jesus Christ to Muhammad to Siddartha Buddha, indivisible, with liberty, justice and equality to all, regardless of preference.

500-year old covered bridge will receive a much-needed, total makeover next year.

bhc newsflyer new

ZWICKAU, GERMANY- It is one of two prized structures spanning the Mulde River that deserves international recognition. However, it is not only the oldest bridge in Zwickau, but the only known bridge of its kind on the globe. The Röhrensteg was built in 1535 and rebuilt to its current form in 1790 after sustaining damage in a flood. The bridge is the only structure in the world that carries two different truss designs- a Queenpost on one side, and a subdivided Warren on the other. It has two different portal bracings: the A-frame on the city end, and an X-frame on the end going to Reinsdorf. The endposts are unlike any covered bridge known to people Europe or North America.  The covered bridge is the only one of its kind that carried water across the river into the city, via wooden pipes coming from a reservoir in Reinsdorf, 4 kilometers east of Zwickau.

The bridge has survived the test of time, including wars, weather extremities (including flooding) and the increase of traffic with bikes and pedestrians. And the age has shown on this structure, as shingles are missing on the bridge’s hip roofing, wood siding is becoming dilapidated, the flooding deteriorating, and some truss beams are deteriorating because of the growth of moss and development of cracks.

Yet because of its unusual design and historic significance, the City of Zwickau, together with an engineering firm in Chemnitz, are working together to restore the bridge. According to the Chemnitz Free Press, the list of what to do with the historic bridge is long: new roofing is needed, along with the siding; new beams and flooring are a must; the strengthening of the structure itself so it can last another couple of centuries is unavoidable, and lastly, the restoration must be done in-kind. That means, restoration must be kept in a way of its original form, using acorn planks.  The cost for the project, according to the city council is an estimated 400,000 Euros (ca. $510,000). However, the project has been approved because of the bridge’s association with Zwickau’s history and heritage, in addition to the wishes of the residents to keep this bridge. The lone catch behind this in funding. According to Thomas Pühn, director of the City Planners Office in Zwickau, the city is applying for state funding to cover the costs for the project. If approved by the state legislature in Dresden, the city will only have to cover 10% of the cost, with 90% coming from the state. The decision lies with the State Department of Transportation and Infrastructure in Saxony (German: Landesamt für Straßenbau und Verkehr).

When all is a go, construction can proceed next year, yet it is unclear how long the restoration will last. In either case, the city and people associated with the bridge are doing everything possible to make sure this bridge will continue to serve traffic while reminding others of its significant role with the history of Zwickau and Saxony’s infrastructure.

The author visited this bridge as part of the tour of the bridges in Zwickau in September 2016. Many more photos and film of the bridge can be found here.  You can also see some other historic bridges in Zwickau that will motivate you into visiting Germany and its historic bridges. 🙂

The Bridgehunter’s Chronicles will keep you posted on the lastest on the project Röhrensteg. The bridge has already been nominated for the 2016 Ammann Awards for Best Kept Secret Individual Bridge and Bridge of the Year. Whether or not it wins  depends on the voting when it commences in December.  Together with neighboring Glauchau and a couple other cities in Saxony, Zwickau is also nominated for the Tour Guide Award.

Under a pile of rubble, there is always a jewel, no matter who or what it is or where it came from. Located 16 kilometers south of Glauchau, along the Mulde River, the city of Zwickau may look like an ordinary community, whose architecture mostly comes from the Cold War. This includes high-rise buildings, mining facilities, old factories and even bridges built using scarce materials possible but only lasting 40 years. In fact, a newspaper report from a local newspaper in Chemnitz revealed as many as 37 bridges in the district of 480,000 inhabitants (of which the city itself has 104,000 residents) that are in dire need of repair or replacement. Most of them had exceeded their expected lifespan by 20 years and are hanging by a thread because of imposed weight limits designed to keep trucks, tractors and busses off of them.

But underneath the doom and gloom of a bygone era, there are some jewels to find. Zwickau prides itself on the automobile industry, where the beloved Trabant automobile was built- now the company belongs to Volkswagen. Audi was founded in this community in 1904. The world’s first known and popular automobile racing union was created five years later.  It also has an international school (Saxony International in Reinsdorf) and a college of science and technology (Westsächsisch Hochschule), making the city a multicultural university town. It has a bridge building firm that has existed since 1854 and still has its base in the city.

And when there is a bridge builder in the community, there will always be bridges, especially given its proximity to the river!

The town was first mentioned in 1118 when the Slavs settled there, yet a half dozen bridges, mostly covered wooden ones were built to connect it with other villages by the 1500s. By the late 1800s, more than 40 bridges crossed the Mulde or surrounded the old town center. Today, if one subtracts the crossings carrying pipelines, only a quarter of the bridges exist in Zwickau, all are along the Mulde. And of these 10 known crossings, counting the Zellstoff Bridge, four of them are over 70 years old. Two of them however have received national accolades because of their unusual designs. They include the Paradiesbrücke- the only known bridge in Germany and the western hemisphere that has the cantilever pony truss design- and the 500-year old Röhrensteg- the only known covered bridge with multiple designs and functions, plus the oldest in Saxony. Both of these centerpieces will be profiled together with nine other structures that will include a couple near Wilkau-Hasslau(to the south) and a couple near Schlunzig (to the north). All of them were built before 1990, but they will present not only the historical aspects of the bridges, but also address the issues involving their ability to carry traffic. A gallery of pictures are enclosed for each bridge I stopped at during the tour in September.

Picking up where I left off in Glauchau, we’ll start the tour going upriver and through the prized automobile and infrastructural community, starting off with our first bridge:

Schlunzig Bridge:

33784867_1900127596684547_7083423144471429120_o

Built in 1954 replacing a wooden bridge destroyed in a flood, the Schlunzig Bridge may be a typical bland concrete beam bridge with little or no value, even if the structure is equipped with the ever so quickly disappearing set of street lighting from the bygone era. Yet its significance resembles two sides of a coin. On the one side, it is a typical East German Bridge, constructed using scarce materials that were prescribed by the Communist government- similar to the Wave at Wernersdorf (for more, see the tour guide on Glauchau’s bridges). Even the lighting originated from that era, which was considered too industrial for the region that is mostly oriented towards agriculture and nature. On the flip side, the bridge is a poster boy for the structural woes the region (and much of Germany) has been dealing with: a run-down structure that is unable to withstand increasing traffic or even weather extremities. As a result, a new bridge was approved by the District of Zwickau in 2016 and it took three years until this product was completed in 2020:

But the replacement plan came with strings attached as issues with the shipment of cables combined with weather extremities delayed the project by up to 12 months. Nevertheless, the cable stayed bridge was opened to traffic in June 2020, while the old span was removed, its remains used for riprap. For the town of Schlunzig, a win-win situation for it has an iconic cable-stayed bridge and it provides better service to the Volkswagen Company, located just west of town.

Fast Fact: The bridge was in fact built in 1959 replacing an earlier span that had been built 21 years earlier but was destroyed in the war. Ironically, the 1938 span replaced an iron truss span that was built in 1878, replacing a wooden covered bridge from 1547. No pictures, postcards and drawings exist at this time, but if you have any that you wish to add please contact the Chronicles.

Zellstoff Bridge:

Entering Zwickau’s city limits, we have the Zellstoff Bridge on the left. Spanning the Mulde River, this bridge features one of the most unusual through truss spans in the region. It’s span consists of a Warren through truss with riveted connections. The portal bracings are skewed at a 45° angle and feature a V-laced form (outer portal) and an I-beam form with heel bracings (inner portal). The struts and vertical beams are both V-laced, as well with the diagonal beams being H-framed. The approach spans feature five spans of a concrete cantilever design. A gallery above will give you a description of what the bridge looks like. Also interesting is a narrow chimney at the left side of the west portal. This may be part of a mechanism that harnessed or even supported electricity, especially as many electrical lines went over this bridge. The bridge served a rail line connecting an automobile factory and possibly an area where mining had existed and therefore, played a key role in Zwickau’s industrial history. But more research on the mining area in Zwickau and in particular, the mini-chimney is needed to help uncover the secrets to the bridge and its surrounding area. The bridge was abandoned after 1990 and there was a plan to remove the structure shortly afterwards. However, thanks to opposition to the plan by residents and preservationists, the decision was scrapped in 2007, and today, the bridge serves as a bike trail between the city and the area where mining had existed. The overgrowth has dominated the bridge and the trail going east, but people can still use them to see what the mining area had looked like before the Fall of the Wall. Despite its age, many people still love this bridge, especially as I met some people while filming it, who all said this one word: “Historique.” That I’m not in a position to disagree with you on. The interest in the Zellstoff Bridge contributed to the City of Zwickau’s successful project in renewing the bridge flooring in early 2018. Since that time, more and more people are using the bridge and even getting some good shots with the camera. A blessing for bridge preservationists, historians and locals alike. 🙂

Here’s a Youtube video on this bridge:

Note: If you know more about this bridge in terms of its history and historic significance to the region, please contact Jason Smith at the Chronicles. The information will be added to the tour guide.

Pölbitz Bridge:

The first vehicular crossing over the Zwickau Mulde when entering Zwickau is located in the northernmost suburb, Pölbitz. Located at Pölbitzer Strasse, west of B-93, this bridge connects Pölbitz with Eckersbach and provides direct access to the nearest town of Crimmitschau. While records indicated the first wooden bridge having been built 1511, the bridge was replaced with a four-span concrete Luten arch bridge in 1914, all with closed spandrels. The bridge withstood years of abuse as a result of flooding, war and lastly, neglect because of the lack of resources and know-how during the Communist era. The straw that broke the camel’s back came with the Great Flood of 2002, which caused extensive damage to the bridge, especially the arches. The city council reacted with a plan to replace the entire structure with a concrete cantilever span, similar to the picture above. The bridge was replaced in 2005-06 with the current structure, which includes some finials and a memorial on the east end of the bridge. A video showing the events involving the Pölbitz Bridge before and after the replacement can be seen below. It includes interviews with those involved in the replacement project and commentary from the anchor, a local who obviously forgot about the arch bridge except for its destitute state.

Eckersbach Bridge:

Spanning the Zwickau Mulde at Kolpingstrasse and highway B-175 , this three-span structure features a concrete deck cantilever design. The bridge is one of the heavily travelled bridges in Zwickau for the crossing provides traffic in and around Zwickau as well as points to the west and north. The current structure was built in 1955 replacing a wooden combination trestle and Queenpost through truss structure that was built in 1898 under the name Socialist Bridge. The bridge was replaced with the current structure in 1955 but not before the floods a year earlier caused significant damage to the new bridge under construction as well as the truss bridge itself.  Between 1898 and 1990, when the name was changed to Echersbach Bridge, the bridge was named with a socialist flair which started with that before changing to the Julius and Ethel Rosenberg Bridge.  Given its age and its wear and tear because of weather extremities and congestion, the bridge has seen better days, and it appears that in the coming years with the increase in traffic, replacement may have to be considered.

Only 150 meters north of the bridge is a pipeline bridge, built using steel plate girders. Built in the 1980s, the bridge carried hot water to Zwickau from sources to the east of the city. Abandoned for a decade, the bridge was removed in 2017 not only for liability reasons, but the residents nearby did not want to see an eyesore obstructing the view of the Mulde River valley.

Maritius Bridge:

The Maritius Bridge is the first of two Mulde River bridges in Zwickau that carry the major highway B93 going south. The steel structure features two bridges: One built in 1992 to accomodate street car service going south and a parallel one built in 1994 to accomodate vehicular traffic. Both structures replaced the Bierbrücke that was built where the present-day Maritius Brewery is located. The structure was first mentioned in 1859 and was built of wood, even though it is unclear whether it was a covered bridge or another truss structure. Furthermore, we don’t know how long the bridge had existed at that time.  After having been destroyed by ice and flooding multiple times, an iron structure was built in 1861. According to some of the postcards, the bridge featured a Town Lattice truss bridge and had three spans. Due to structural concerns, the bridge was closed in the 1970s. It was rehabilitated in 1975 to accomodate pedestrians and cyclists by replacing the truss spans with steel beam and was raised a meter to allow for free flowing waters of the Zwickau Mulde. Inspite of this, the partial permanent closure of the Bierbrücke resulted in a complicated detour through other parts of Zwickau where massive traffic had not been seen on residential streets.  

Because of lack of funding due to the economic conditions in East Germany during that time, reconstruction was only possible after the two Germanys were reunited. Come 1992, the first of two bridges were built to provide street car service to Eckersbach from the city center. By that time, the old Bierbrücke had vanished into history. Two lears later, as part of the B-93 expressway project, the second bridge was built for traffic. Today’s Maritius Bridge is the gateway to Zwickau from neighboring Glauchau and points to the north along the expressway connecting the city with Leipzig.

Paradise Bridge (Paradiesbrücke):

Germany was once known as a place filled with ornamental bridges built using unusual designs. Despite 90% of them being destroyed during the Third Reich and through the bombings in World War II, there are still some diamonds in the field that if found are worth researching and given its rightful honor. The Paradise Bridge, located at Nicolai and Reinsdorfer Strassen near the Nicolaischule and Eberts Palace is one of those bridges that deserves international accolades, as well as its neighbor upstream, the Röhrensteg.  Having been considered a cultural heritage site (Kultutdenkmal) by both the East German government and later by the State of Saxony since 1980, here are some interesting facts worth noting about this bridge:

1. The bridge was the first one of its kind that features a cantilever pony truss design. Furthermore, it was the only known cantilever truss bridge whose trusses are supported by only one tower. Before the completion of the new Küblers Bridge in Lunzenau, located 45 kilometers downstream, in 2017, none of the bridges known in the western hemisphere had had that unique design.

2. The bridge was built in 1900 by a bridge-building firm Beuchelt & Company in Grünberg in Schlesia (now part of Poland), replacing a covered bridge, which was one of over 30 that were built in Zwickau. The predecessor was built in 1694 by Johann Georg Findeisen from Schellenberg at a cost of 200 Taler. The covered bridge was one of the fanciest of the dozen built in Zwickau and it had come in response to multiple previous crossings that had been built but had survived briefly as they had been destroyed by ice jams, flooding and war. The Findeisen span had been in service for 306 years before it was decomissioned and dismantled in favor of the cantilever truss bridge.

3. The structure itself is 120 meters long, its tower is in the middle of the Mulde River. The width is 15 meters, counting the trusses. Since 1979 and inspite the restoration work in 2003, the bridge has been serving cyclist and pedestrian traffic, carrying a bike trail connecting Zwickau’s City Centre with Reinsdorf, located four kilometers to the east.

Its replacement structure is found 200 meters west of the bridge at Dr. Friedrichs Ring (Hwy. 173). That bridge, known as the Adolf Hennecke Bridge and later from 1990 onwards as the Glück-Auf-Brücke, was built in 1979 and connects Zwickau with Chemnitz to the southeast. That bridge is three times as long and twice as wide as the Paradiesbrücke, spanning the river, Highway B-93, the Mulde Bike Trail and Reinsdorfer Strasse.

4. When the bridge was renovated in 2003, the towers were crowned with finials resembling the Matthäus Kirche (St. Matthew’s Church) which was located 400 meters east of the entrance. Additional decorations on the trusses and ornamental lamps were also added making the bridge more attractive to tourists and passers-by.

5. The bridge is located near the site where a former mine and bridge building company used to be located. A memorial site with a miner resting with a beer in the hand can be seen 100 meters northeast of the city side of the entrance. It is also located near the Ebert Palace, whose finial towers can be seen above the trees at the bridge’s east entrance.

6. The bridge was the platform for several historical events affecting Zwickau and beyond. For instance, the name Paradies stammed from Martin Luther’s visit in Zwickau, where he crossed the bridge in rage after a row with the priests before entering a nearby house and declared: “Thank God I found this house. Here is my paradise.” The first was an open-air festival in 1847, featuring a concert by musicians Robert Schumann and his wife, Clara. For two weeks after the end of World War II, the bridge served as a temporary border crossing for American and Soviet troops. That ended in July 1945. And in 1956, a film production in Zwickau included a couple scenes on the bridge. The restoration of the bridge in 2002/03 came after floodwaters almost knocked the bridge off its piers. And most recently, an open-air cafe used to be on the bridge, which happened in 2017.

Pöhlau Railroad Bridge:

Located near the site of the International Trabant Museum, this bridge appears to be one of the newer truss bridges built no earlier than 25 years ago. While its light brown color makes it look rusty in appearance, its “molded” connections is typical for today’s truss bridges. The Warren through truss bridge with beam portals and Lattice truss overhead bracings used to serve a rail line connecting Pöhlau and Zwickau Central Station. The bridge and the line are now abandoned. Given its age and modern appearance, chances are this bridge will be reused at some point- either as a crossing for cyclists in its place, a street car crossing going south or a railroad crossing at a new location. Time will tell what the City of Zwickau will do with this structure.

Röhrensteg:

Like the Paradiesbrücke, the Röhrensteg (translated as the Bridge of Pipes) is another key attraction for Zwickau which should receive international recognition for its design and function. The bridge’s history dates back over 500 years to 1535, when the bridge was first built. At that time, the people in Zwickau needed water for their personal and commercial use. Because the water of the Mulde was dirty and not drinkable, the only source of clean drinking water to be found was at a pond near Reinsdorf- three kilometers away from the bridge. Henceforth, workers created man-powered pumping stations and pipelines made of hard wood from oak trees. The trees were cut down, and after stripping the bark and outer layers, a hole with a diameter of 30 centemeters was dug out by hand, but not before having cut the wood into sections and then connecting them once the hole was “drilled.” The wooden pipeline then transported water down the hill and across this bridge before being distributed throughout the city. A section of this wooden pipeline can still be seen on the bridge, where the overhead beams are still supporting it, providing proof that this practice once existed. A total of at least 17 wooden pipelines had been built for the city of Zwickau to provide drinking water for the community, four fountains where the wooden pipes were connected dating back to the 1700s have been preserved as exhibits at the city center to show this unique engineering feat. This pipeline system was later replaced with more modern systems in the early 20th century, but the bridge itself has withstood the test of time and mother nature. Despite having had substantial damage during the flood of 1790, the Röhrensteg was rebuilt and has retained its original form ever since. The bridge has survived numerous floods and other natural disasters, even after new pier casings were installed in 1940 as part of the project to dredge the Mulde River.

In terms of its structure, the Röhrensteg is the only truss bridge (wooden or metal) to have two different designs and two different portals. The bridge features a three-span Queenpost truss design on the western side and a subdivided Warren truss on the eastern side. A-frame portal bracing is found on the city side, X-frame lattice with heel bracings on the Reinsdorf side. Endposts with 45° angles can be found at each portal; together with the wooden siding lining up between the bridge and the abutment, this makes the Röhrensteg one of the most unusual covered bridges to have ever been built. Roofing is of hip style with an angle of 45°, which is similar to the covered bridges found in Switzerland. The bridge serves a bike trail connecting Zwickau’s southern part and Reinsdorf via Oberhohnsdorf, serving as a spur to the Mulde Bike trail that careens along the river.

Despite its unusual design and multi-functionality, the bridge is showing its age, and therefore needed to be rehabilitated. This work was completed during three quarters of 2018, having been reopened to traffic in January 2019. Details can be found here. Prior to the rehabilitation,  new approach spans on the Reinsdorf side and the pier casing had been built,  no extensive work has been done on the bridge prior to its extensive work. More on the work can be found here.

A youtube video on the Röhrensteg takes you across the bridge and to the pipes found in the superstructure itself. Check it out:

 

 

Röhrensteg after its reopening in 2019:

Schedewitz Bridges (New Schedewitz Bridge and Bockwaer Brücke):

Located in the suburb bearing the bridge’s name, the next two bridges are located only 200 meters from each other, each spanning the Mulde. The older bridge is a two-span Warren deck truss without verticals but with stone arch approach spans. Built in 1890, this bridge used to connect the suburbs of Schedewitz and Bockwa, hence it was known by locals as the Bockwaer Brücke. Its predecessors consisted of a multiple-span stone arch bridge that was built in 1842. The northern two spans of this bridge were preserved and used as approach spans for the Warren truss spans. Yet the first crossing was a covered bridge, which was built in 1661. The bridge used to serve a key route along the Silver Road, connecting Zwickau with Schneeberg via Wiesenburg. Much of that route has been taken over by the federal highway B-93.  Furthermore, the bridge used to have a streetcar route and a two-lane vehicular crossing.

Because of flood damage in 1954, contract was let to the local bridge building firm VEB Brückenbauwerk Zwickau in 1956 to build its replacement span, located 200 meters downstream at the site where the crossing exists today.  The new span features a three-span concrete cantilever span, with a length of 70 meters, accommodating four-lanes of traffic plus sidewalks. Construction lasted two years due to difficulties digging through the steep cliffs, requiring the use of explosives before the cliffs were dug out. The road was then laid out, which included a side road that would connect with the main route from the old Bockwaer Brücke before continuing onto Schneeberg. . This was useful for the highway was later extended to the south enroute to Reinsdorf, the motorway exit Zwickau-Ost and later Hartenstein.  The new bridge has been serving traffic for over 60 years but age and wear and tear may warrant a much-needed rehabilitation in the future.

As for the Bockwaer Brücke, once the new Schedewitz Bridge was opened to traffic in 1958, work commenced to remove the street car tracks, plus halve the roadway to a point where only bikes and pedestrians could use the old bridge. The bridge was then raised 2 meters to avoid damming the river in the event of flooding. Today, the bridge still serves cyclists and pedestrians but work may be needed to make the structure more functionable. Already the Zwickau City Council rejected a proposal to rehabilitate the bridge in 2017, which raises questions on the bridge’s future. Will there be enough locals willing to convince the city council to reconsider, or will indifference and a strive for modernization doom the old structure, whose history is worth preserving, especially as it is part of the history of Zwickau and the Silver Road?

 

zwickau_cainsdorf_-_cainsdorf_bridge_2009_28aka29

Cainsdorf Bridge:

Another important crossing to mention is the Cainsdorf Bridge. While little has been written about its history, the 1929 two-span steel deck plate girder span crosses the Zwickau Mulde at the railroad station along the Zwickau-Aue-Johanngeorgenstadt line. The bridge connects Cainsdorf and areas to the west and the eastern edge of Zwickau between Oberhohndorf and the city of Wilkau-Hasslau and provides the lone access to the Planitz district, which includes a restored castle and church, where the present-day Clara Wieck Gymnasium is located.  Sadly, the bridge’s condition has deteriorated to a point where only a three-ton limit has been enforced for all vehicles except the city’s bus line. The good news is the bridge is expecting a replacement bridge, to be built on a new alignment connecting both areas, but towards the Oberhohndorf district, thus cutting down the time needed to get to one’s destination in either way. Construction is expected to start in 2019 and finish by 2021. Afterwards, the historic bridge will undergo a thorough rehabilitation that will prolong its life but also allow for only cyclists and pedestrians to cross. This will be a big advantage especially those wishing to catch the train from the train station next to the bridge. A win-win situation that many locals with ties to the bridge will benefit from.

Wilkau-Hasslau Pedestrian Bridge: 

Five kilometers further upstream and biking past the Cainsdorf Bridge is the pedestrian bridge at Wiklau-Hasslau, the southernmost suburb of Zwickau. There, one will find a rather unique pedestrian bridge. Built in 2004, the bridge features a pen-like tower, with cables supporting the roadway and the tower itself. The roadway has a curve, allowing cyclist from the east side and Schneeberg to enter as a ramp, as it curves to the right towards the west end. The 145 meter long pedestrian bridge crosses the Mulde River and a pair of railroad tracks that provide train service between Zwickau and Aue to the south. The valley’s hilly and wooded scenery is what the Wilkau-Hasslau Pedestrian Bridge has to offer- along with a short break at a modernized city center, which has a weekly market- before biking on to some more bridges. The tower has a height of 32.2 meters, making it the tallest bridge in Zwickau. Yet to the south of the bridge is an even taller bridge carrying the Motorway A 72. Built in 1995, that bridge spans the deepest of the Mulde River valley in Zwickau, but is the second longest bridges along the stretch between Hof (Bavaria) and Chemnitz.

Kirchberg (Mulde) Bridge:

To the north of the pedestrian bridge is the Kirchberg Bridge,  perhaps the longest of the “at-level” river crossings over the Zwickau Mulde in the greater Zwickau area. When looking at the bridge from the pedestrian bridge, one could guess that the stone arch bridge, built using sandstone, had three arches. Yet when walking along the streets of Wilkau-Hasslau to get a better, closer look at the bridge, one can see the number of spans being more than double. In fact, eight spans glide over the river and the flood bed with a total length of between 300 and 400 meters. Records reveal that the Luten arch structure was built in 1867 but it appears to have been widened in the early 1990s to better accomodate traffic between the joint community (which was established in 1934) and Kirchberg, located five kilometers to the southwest. This bridge has shown its age as cracks are appearing in the stone arches. Despite emergency repairs in 2018, a full-blown rehabilitation project to prolong the crossing will most likely occur sometime in 2020. When this happens, most likely the West German style flourescent lighting will disappear in favor of fancier, ornamental lanterns with LED-lighting, which will present a more appropriate flavor for Wilkau-Hasslau.

Motorway 72 Viaduct

The tallest and longest of Zwickau’s bridges is not located in Zwickau directly, but in neighboring city Wilkau-Hasslau on the south end. The motorway viaduct was originally built in 1937-39 as part of the construction of the motorway connecting Hof with Chemnitz. Ironically, the entire stretch of the highway was not finished until 1993 due to delays caused by World War II and the division of Germany that followed. This stretch was the last built prior to the start of the war and would be used heavily after the war ended. The motorway viaduct continued service until 1995, when it was replaced with a new steel girder viaduct span, built on the piers of the original bridge. The total length is 670 meters with a height of 50 meters, making it one of the longest along the original stretch. It can be seen when entering Wilkau-Hasslau from the northern side.

Marienthal Viaduct

Approximately 350 meters north of the Central Railway Station is the Marienthal Viaduct- the only bridge in this tour guide that does not span the Zwickau Mulde. Spanning a small but deep creek as well as Werdauer Strasse, the eight-span stone arch bridge is the longest in Zwickau, with a total length of 94 meters. With a height of 14 meters above the ground, it is also the highest. If counting the Motorway 72 Viaduct in Wilkau-Hasslau, it is the second longest in this tour guide. The viaduct is the shortest of the noted viaducts along the Nuremberg-Hof-Dresden Magistrate with the next ones in both directions being at least twice as long. The bridge was built in 1869 as the railroad was being built for Zwickau from the east. It was built using red brick, sandstone and porphyr. The bridge still sees use on a daily basis for as many as 10 trains cross this bridge per hour; most of them passenger train services connecting Zwickau with Glauchau, Chemnitz and Dresden. Albeit a regional service route, it is expected that this route will be connected to the long-distance train in the future, for the Bahn plans to electrify the line south of Hof and in the end have InterCity trains going from Dresden to Munich.

A map of the bridges in Zwickau is enclosed in case you would like to visit the bridges yourself. Some of the bridges are mystery bridges where an article has been written on each one and can be found in the Chronicles. Others feature just a pic of the bridge indicating its existence but has no information on it to date.
