The Wave Is Getting Accolades

 

GLAUCHAU (SAXONY), GERMANY-  It had been once considered an absurd project- a replacement bridge fit for bikers and pedestrians instead of a vehicular bridge. The project was criticized for its delays due to weather and other circuzmstances related to construction. Since June of this year, the Wave, spanning the Zwickauer Mulde River near Wernsdorf, south of Glauchau in western Saxony, has been serving the Mulde bike trail, going south to Zwickau.  Now the Wave is getting its first accolade and is in line for another one. The bridge, consisting of a concrete suspension bridge- whose roadway is draped over the pylons implanted in the riverbed- just recently received the State Engineering Excellence Award from the State of Thuringia.

But why Thuringia, when the bridge is in Saxony?

According to sources from the Free Press, it was simple. The engineering firm that constructed the Wave, originates from Weimar. Setzpfandt Engineering was founded by Gerhard Setzpfandt in 2015, whose engineering career spans over 25 years. Since its opening, the engineering firm has several projects completed to their name with many more on the table. This includes projects in Saxony-Anhalt, Hesse, Thuringia and greater Berlin. Because of its unusual design, which is the first of its kind, the state of Thuringia awarded the prize to the engineering group and with that, the City of Glauchau, even though it is the state’s first award to be given out of state.

I happened to visit The Wave during a bike tour in October and presented a video to show you what the bridge looks like and how it feels walking across the “roadway-style” suspension bridge. Have a look below:

 

 

There will be many more accolades to come for this unique bridge, even if it’s still controversial in the eyes of those who would have preferred a vehicular crossing. But with additional bridge work happening at Schlunzig, that dream will be fulfilled.  The Wave is in the running for another award, the Othmar H. Ammann Awards in the category Best Kept Secret- Individual Bridge. Whether it wins the award depends on the voting process, which will begin in December via the Bridgehunter’s Chronicles.  The Wave is also one of five additional bridges in Glauchau that were added to the city’s tour guide earlier this year, hence the decision to re-enter Glauchau in the Ammann Awards in the category of Bridge Tour Guide. Again, the winner of the awards in that category is dependent on the voting.

More details on who else is in the competition in the six categories will come on December 4th. Stay tuned. 🙂

What to Do With a Historic Bridge: The Schlema Stone Arch Bridge in Germany

Photos taken in September 2017

AUE/SCHNEEBERG (SAXONY)-

Our next stop on the bridgehunting tour, especially along the Zwickauer Mulde in western Saxony is the town of Bad Schlema. This town of 5,600 inhabitants is located deep in the Erzgebirge (Ore Mountains) where the river meets the River Schlema. It was once a key junction of two rail lines: the still existing north-south railroad that connects the community with Aue and Johanngeorgenstadt to the south as well as to Zwickau-Werdau-Leipzig to the north. The other is a short line going west to Schneeberg that used to provide passenger and freight serviceS but has been extant for over 60 years. Both lines were vital for transporting iron ore from the mined regions to the processing plants in the larger cities in the mountains. Nowadays the current line provides access for people wishing to visit the radon health resort in Bad Schlema, which has existed for over a century as well as the Christmas markets in Aue, Schwarzenberg and Schneeberg.

And while the train station at Bad Schlema still provides passenger service on the north-south axis, the surroundings that made the station famous are all but a faded memory. This included the Leonhardt Paper Company, the Hoffmann Machine Factory and Tölle Machinery, the third of which manufactured iron products. By 2006, the last remaining factory, the paper manufacturer, became a memory thanks to the wrecking ball.  The only relict remaining that serves as a reminder of the good old days of mining and paper production are a pair of historic bridges spanning the Zwickauer Mulde: a truss bridge dating back to the Communist era and a stone arch bridge that had existed since the creation of the rail line, but is in disarray to a point where questions are being raised as to which bridge should be saved and which one should go.

 

Before going to my investigative reporting, look at the slide show below and ask yourselves this question: Which bridge would you want to see saved and which one would you like to see gone? And what are your reasons for your decision? And how old do you think these two structures are?

 

This slideshow requires JavaScript.

After doing some thinking about it, let’s take a look at the history behind the two bridges, which is in connection with the railroad itself. Between 1856 and 1860, the railroad company decided to construct a line going into the Ore Mountain region in western Saxony, where it was rich in various metals and miners had been working the region for generations. The line started from Zwickau and by 1860, the line arrived in Aue before terminating at Johanngeorgenstadt, near the present-day Czech border by 1868. Between Aue and Schlema, the rail line made a hook going around the mountain, running parallel to the Zwickauer Mulde. Because of its narrowness, combined with dangers of rock slides and curves, a decision was made to straighten the line in 1895, which included building a tunnel between the stations of Aue and Schlema, the latter was named Niederschlema at that time. As seen in the map and illustration, the distance was trimmed by half, and a single-span duo-truss bridge eliminated a single-lane bridge, thus making it easier and quicker to ship people and goods between Aue and points to the north and west. At the same time, another bypass north of Niederschlema was built going north to Hartenstein, which ran parallel to the Zwickauer Mulde and the present-day road connecting both towns. The realignment project was completely finished by 1900, but it came at the cost of the original rail line and the Stone Arch Bridge itself.

The response, according to Dr. Oliver Titzmann was an overwhelming support by the paper company to take the redundant line and bridge and make it their property. In an interview with the Bridgehunter’s Chronicles, Dr. Titzmann, the town historian and member of the Bad Schlema City Council, has done a lot of research on the railroad and the Stone Arch Bridge itself. That bridge was built in 1860 and featured two Luten arches as main spans, plus a pair of shorter arch spans as approaches. Upon personal observations, the bridge was built using two different types of rock: sandstone and quartzite, the first of which appears harder on the surface. The spans are skewed at 30°, which is unusual for arch bridges, yet its purpose still remains the same: to provide the river with free-flowing passage without damaging the structure. While there is no concrete information on the structure’s dimensions, upon personal visit, it appeared to be 65-70 meters long and 12-14 meters wide.   According to information by the historian, as well as reports by the Chemnitz Free Press, the Bridge was made redundant by a Communist-era through truss bridge, built using a Warren design in the 1980s, and served the line going through the paper factory until it was closed down in the mid-1990s. Abandoned since then and fenced off to prevent trespassers from crossing it, the community would like to see the Stone Arch Bridge rehabilitated and reused with the truss bridge being removed because it’s an eyesore.   Dr. Titzmann has been a vocal supporter for saving the Stone Arch Bridge, the last of the original crossings  along the Zwickau-Aue branch of the north-south line and integrating it into the Mulde Bike Trail, which currently shares the road to Hartenstein from the train Station in Bad Schlema.  Like the overwhelming support by the now extant paper factory during ist existence a century ago, support is enormous among the community for reusing the Stone Arch Bridge, which has been abandoned for almost four decades. Already the company owning the eastern bank of the river where the Bridge is located, Wismut Mining Works, has worked on clearing space for the bike trail, which has cost them over 300,000 Euros to date. The State of Saxony has already contributed 145,000 Euros for the rehabilitation of the structure.

The plan, according to Dr. Titzmann is simple: as seen in the map, the bike trail is to follow the original railroad line, but running underneath the tunnel at the Bad Schlema train station, utilizing the Stone Arch Bridge, and going past the Wismut Mining Works, using the Poppenwald Road that goes there, as it was originally part of the line, before joining the current bike trail in use at Hartenstein.

The problem, according to Dr. Titzmann, is more complicated than expected:  “The center pier of the bridge has been undermined over the years, thanks to flooding and erosion,” Titzmann stated during the interview. “Therefore, as a person can see, the roadway at the center of the bridge is sinking.”  Aware of the complications, the community is working together with the state in securing additional funding to rebuild the bridge, keeping it in its original form to avoid being scratched from the Denkmalschutz book. This is the German equivalent to the National Register of Historic Places in the United States, except the bridge is listed on the state level because of its design and connection with the history of the paper and mining industries in the Erzgebirge.  The state level is one of three that are used to list historic places in the Denkmalschutz Book, along with local and national levels. Had the Stone Arch Bridge been listed in American standards, it would have fallen under the criterien of A (Events) and C (Design and Construction). Yet while funding for rehabilitating bridges in the States has become scarce, in Germany, money is kept available by the federal and state governments to encourage ambitious projects like this one, even if the project is complicated because of the aforementioned reasons.

The reconstruction project falls on the state level and it is a matter of time before the state of Saxony provides some additional funding in order for the project to move forward. The cost for rebuilding the bridge alone will take between 120,000 and 150,000 Euros, which consists of stripping the bridge down, while retaining the original stonework, rebuild the center pier, and then rebuild the structure, piece by piece before adding the decking and railing. The reconstruction of bridges in this style is very common in Germany, with the Camsdorf Bridge in Jena (Thuringia) being the closest example to the Stone Arch Bridge in Bad Schlema. That bridge, built in 1913 and rebuilt in 1946, was reconstructed and widened to accommodate more trams and cyclists. Completed in 2005, the project had taken two years.

Once the Stone Arch Bridge is completed, the rest of the bike trail can be built, thus reactivating a part of history that had not existed for over a century. Already a section of the bike trail north of the train station had been built on the west end of the river approaching the bridge but if funding and support arrive in a timely manner, the project could be finished in two years or less. This includes the removal of the truss bridge.

In the meantime, as funding and technical know-how is being pursued to realize this project, cyclists are still fighting with traffic along the road between Bad Schlema and Hartenstein, one of a few stretches of the 240-km long Zwickauer Mulde Bike Trail. And even though a stretch of rail line between Aue and Wolfsgrün has been part of the Mulde system for seven-plus years, when the renovation of the bridge and realignment of the bike trail are both completed, an additional 10 km of rails to trails will be added, which will mean less stress while on the road, but at the same time, more opportunity to enjoy the Zwickauer Mulde, the natural landscape and a little history about the line passing through the region, which had once connected Leipzig with the Czech Republic and provided goods and services.

And when the bridge is finished, one will only see the arch bridge that was once abandoned but is now a historic site- seen by the train leaving Bad Schlema for Zwickau instead of the Communist eyesore, which many will not shed a tear once it’s gone.

Mystery Bridge Nr. 87: A Bridge with an Unusual Railing and Plaque

21199489_1615769091787067_2287244526147575239_o

 

Our 87th mystery bridge takes us down to Saxony again and to the town of Eibenstock. Located 13 kilometers southwest of Schneeberg and 22 kilometers west of Aue, this community of 7,000 inhabitants feature not only one but thirteen different sections that had once been villages, all located within a 122.2 squared kilometers from each other, meaning approximately 68 people per square km. At at a height of 650 meters above sea level, Eibenstock is one of the highest communities in the Erzgebirge (Ore Mountain region). Founded 862 years ago, the community was one of the main centers for nickel and copper mining in the region. Much of the architecture from the 17th and 18th Centuries have remained in tact, including the churches, the Post Mile and the historic town center. There, one can find mini fairy tale huts with scenes from over a dozen stories. The town is located south of the Eibenstock Reservoir, an artificial lake that was created with the Dam, built in 1984 to control the flow of water from the Zwickauer Mulde River. Prior to that, the river valley was one of the deepest in Saxony and one that required both a railway line from Chemnitz and Aue but also a steep cable-line car to Eibenstock, once the steepest in eastern Germany. Both gave way to progress with the dam and reservoir. But even the lake provides some boating, fishing and hiking opportunities in the summer time, a complement to its traditional skiing and winter amusement area between the lake and the community.

And while the Zwickauer Mulde flows past the town of Eibenstock through the lake bearing its name, two creeks flow through the town, merging at the town square at the corner of the town’s elementary school: the Dönitzbach and the Rähmerbach. From there, the newly merged Rähmerbach flows quickly down the steep valley and empties into the Reservoir, only two kilometers away.  Several arch bridges cross the two creeks in Eibenstock- the classical stone arch bridge as well as modern arch bridges whose decking and railings curve upwards. With each span having a length of 5-10 meters, it is easy to overlook them because they are typical structures a person could even jump over. However, one cannot overlook this structure:

IMGP9148

It is a short beam bridge with a length of 9-10 meters and 8 meters wide. It spans the Dönitzbach carrying Bürgermeister Hesse Strasse at the market square on the opposite end of the elementary school, where Winklerstrasse meets.  While one may look at it as just a short bridge, the uniqueness comes with the railing on the side facing the market square.  There, we have a curved railing with vertical ends, all made using sandstone brick. At the center of the span, the top portion makes a U-shaped dip deep enough to include an iron shield. Curved and ornamental, the shield represents the symbol of luck, featuring a long rake in the middle, a three-leaf clover on the left and a miner’s chisel on the right. One can assume that given Eibenstock’s location in the Erzgebirge, the shield goes by the slogan “Glück Auf!” which means either “Good luck!” or even “Hello!” in German. In fact, the Erzgebirge Region has three characteristics that make it special: woodwork, mining and farming. When visiting the Christmas market in Germany and visiting the booth selling products from the Region, be it a lighted Christmas arch (Lichterbogen), Christmas Pyramid or any wooden products as well as metal bracelets and figures, one will see how they are handmade, going from forest or mines through the whole process into the fine product to be given to your loved one for the Holidays.

IMGP9150
Close-up of the iron shield with the markings typical of the Region. Any ideas how old this is?

 

But going back to the mystery bridge, the structure appears to have been built most recently, going back no more than 10 years, and the railing and iron shield stemmed from the structure the present bridge replaced. This can be seen, especially with the shield, as it has shown some wear and tear over the years with rust and corrosion appearing especially on the back side. The question is what did the previous bridge look like? Did it look like the stone arches that still exist in Eibenstock? When was it built and if the shield was part of the original structure, since when, and who designed it?

 

If you have any answers, then we’ll be happy to take them. Just drop a line and we’ll update this bridge until the mystery bridge is solved.

Bockau Arch Bridge Closed; Coming Down in Favor of a New Bridge

bockau1

Bridge built in the 1600s to be replaced on a new alignment. Petition to reuse the bridge for pedestrian use still in the running.

AUE (SAXONY)/ DRESDEN/ BERLIN-  While we read about historic bridges being demolished we mostly find metal truss bridges, between the ages of 70 and 130 years, that are coming down, despite having potential of being reused. We almost never see a stone arch bridge that meets the wrecking ball, regardless of age.

That is unless you look at and read about this bridge, the Bockau Arch Bridge, spanning the Zwickauer Mulde River at the village of Bockau, six kilometers southwest of Aue and exactly the same south of Schneeberg in the Ore Mountains (Erzgebirge). Built in the 1600s, the bridge is located near the historic Rechenhaus (Headworks House), dam and waterway, which had been built between 1556 and 1559, providing drinking water to the villages along the river. The crossing was essential for miners needing to use the bridge as they cross between Zschorlau and Schneeberg on the northern side and Bockau on the opposite side of the river. The five-span stone arch bridge, made using sandstone, was rehabilitated in the 19th century and survived a scare in April 1945, when Nazis tried to implode the structure in a failed attempt to stop the advancement of Russian troops from the east and Americans from the south and east. American troops from the 11th tank division occupied the bridge before the Nazis could demolish the structure.  Despite this, plus two major floods that caused damage to the structure (the last resulted in adding steel bracings to the arches), the bridge remains in decent shape- at least from my observations- although potential rehabilitation is needed to prolong its life much longer.

bockau2

Despite its historic status, the 400+ year old structure is coming down. Crews are cutting down trees in a plan to build a new structure to better accomodate traffic from Schneeberg and Zschorlau while at the same time, realign German highway 283 to eliminate the sharp curves the historic bridge presents to the highway. According to the Saxony Ministry of Transportation and Infrastructure, the bridge will be a straight crossing, having a modern style with skewed approaches. The highway will be expanded into an expressway, merging traffic with that from Bockau. This includes bike and pedestrian paths. In addition, new retaining walls at the new bridge will be needed and the rock escarpment that flows down through Bockau into the Mulde will be redone. In the last phase of the project, which will be completed by November 2019, the historic bridge will be removed. This will happen towards the end of next year, unless waves are made by locals and politicians to keep the bridge in tact to be reused for pedestrian purposes.

A petition was created in April of this year, calling for the bridge to be left as is, even after the new bridge is built because it retains its historic character and is protected by the German Preservation Laws (Denkmalschutz Gesetz). In addition, three rare species reside at and near the bridge, including the fire salamander, different species of bats and the water ouzer (dipper). Calls for saving the historic bridge is gaining momentum, as even members of the German Green Party are calling for the bridge to be saved for the aforementioned reasons. Still, resisitance has been ignored for the State of Saxony has rejected plans for a two-bridge solution, and the Federal Government, which is footing the 6.4 million Euro project, expects the historic bridge to be demolished by November 2018.  The fight is still on but time and resources are running out, especially with every tree that is being cut down for the project, as the author observed during his visit on the 28th of August.

bockau5

bockau4
In this picture, you can see how the new alignment will look like, with Highway 283 in the background.

Already the bridge is closed to traffic as of the 28th of August, as seen from my visit. The Zwickauer Mulde Bike Trail (which runs under the historic bridge) is also fenced off, with a detour following the current highway and street going to Schindlerswerk on the southern side of the river. The 1.5 kilometer detour is expected to remain in place until November 2018, when the bridge is removed. Highway 283 will be detoured from Aue through Zschorlau and Albernau beginning in September and lasting until the completion of the project in November 2019. Local traffic between Bockau and Aue will remain open with some restrictions.  Whether this plan will still take hold, depends on the progress of the petition for the preservation of the old bridge and whether authorities in Dresden and Berlin will concede and allow the locals to keep their bridge. Should that not be the case, this project may have some repurcussions with other projects in the pipeline, including the plan to replace the Chemnitz Viaduct to better accomodate the German Railways’ (the Bahn) InterCity trains. That project, which has been stalled due to stark opposition from locals, the state historic preservation office and other experts in bridge preservation, is also being backed by Berlin as the Bahn is partially owned by the government.

bockau3
Historic Bockau Bridge is now closed. Chances of saving the structure, let alone photograph it are getting slimmer by the day.

If you want to sign the petition to save the bridge, click onto the link and include your name, address and reasons for saving it. Never say never if you want your historic bridge kept in place once the project is finished. The Chronicles will keep you posted on the latest.

Wolkenburg Suspension Bridge: A Unique Cable-Stay Along the Mulde

wolkenburg2

Wolkenburg (Saxony)/ Limbach-Oberfrohna/ Glauchau- The last of the three bridges profiled here that is debuting along the Zwickauer Mulde is the Wolkenburg Suspension Bridge. Before going further with this bridge, we need to clarify what this bridge looks like as well as its aesthetic value. The current structure, open since May Day this year is actually a cable-stayed suspension bridge, a bridge type where suspenders actually support the roadway from the tower. When looking at them from an American’s point of view, cable-stayed bridges are bland in appearance, ranking them up there with concrete slab/girder bridges that represent a sour taste to the land-/ or even cityscape. This can be best exemplified with two bridges that come to mind: The Fort Steuben and the Russell-Ironton Bridges. Both of them spanned the Ohio River; both of them have the characteristic A-frame tower, whose cables support the roadway; both of them replaced historic bridges that had a lot of characteristic and aesthetic appeal but were neglected by the department of transportation in a successful bid to have them replaced. Both of them have been demolished, leaving nothing but documentation on websites owned by James Baughn and Nathan Holth, respectively. Both bridges are prone to having problems in the short-term involving the cables and the roadway because, like other modern bridge types, there is too much (heavy) traffic using it. We’re even seeing it with a pair of bridges in Germany, which will be mentioned later on.

wolkenburg3

But while these cable-stayed bridges are being looked down upon like the other concrete spans in America, pursued by Donald Trump and Elaine Chao with some statues of Paul Ryan and Mitch McConnell and a new quasi-national flag of the US (sorry, I have to be sarcastic with this analogy), cable-stayed bridges in Europe, from an outsider’s point of view, can be viewed as a treat, especially for pedestrians and cyclists using them while on the bike trail. One in three cities in Germany has at least one of this type. And while there are some standard examples that exist, most of the cable-stayed bridges we find here are designed in such an unusual way, that they are screaming for people to stop by to pay homage; whether it is because of tilted towers, curved or even rounded roadways, ….

wolkenburg4

 

or in the case of this bridge, a single tower that is leaning outwards towards the river bank, whose primary cables- all draped over a pointed tower- are supporting the deck. The deck itself has a pony girder approach span with a Warren pony truss main span that crosses the Zwickauer Mulde.

 

wolkenburg6

The bridge replaced a century-old structure that consisted of a wire suspension bridge, going by the textbook guidelines that were created by another German engineer, John Roebling. Roebling’s concept was strands of thick wire that were spun together to create the main cables that were anchored between the towers and the ground anchors on shore. The best examples of his design were the Cincinnati-Covington Bridge (1869) and the Brooklyn Bridge (1883, though he died during its construction). The original Wolkenburg Bridge featured heavy cables  combined with vertical suspenders that supported the narrow walkway. The walkway itself was fenced with heavy wire but not trussed like one will see in many suspension bridges today, such as the Golden Gate Bridge or the suspension bridges in New York designed by Othmar H. Ammann.

 

Flooding in 2013 caused extensive damage to the bridge’s roadway and cables to a point where officials in Limbach-Oberfrohna, where Wolkenburg is part of the conglomerate, as well as local officials decided to demolish the bridge, including the tower, which was arched and made of concrete. It took more than three years, combined with lots of money and politicking before the conglomerate let the contract to the firm of Iroplan, based in Chemnitz, and its architect, Klaus Lenz, to build a new bridge at the site of the old one.

 

Construction started in 2016 with the leaning tower and foundations. The roadway was assembled offsite, featuring sliding and welding connections, judging by the author’s observations during his visit. The roadway was lifted into place by crane in November that year, and after attaching the cables between the tower and the roadway, the bridge was completed. What was not completed at the time of the visit in March were the roadway leading to the bridge, the dike to keep the water in the river, and painting the bridge. The bridge was still grey and silver.  The cost for constructing the 80 meter long and two meter wide cable-stayed bridge was 1.2 million Euros.

wolkenburg5

After many delays and headaches, people have their bridge back. At the May Day opening, where many people participated, mayor Jesko Vogel led the opening with a bang, as cannons were fired and a historic theater group from Glauchau were on hand for some entertainment. Refreshments were provided by the fire department. While the suspension bridge will forever be in the memories of many who live in Wolkenburg, this bridge reopens a connection between Eichenwald Forest and the mill area, both are northeast of the historic city center. The bridge will be a new icon  for Wolkenburg, providing a picturesque view from the historic city center and its churches and castle on the hill. And contrary to common belief regarding cable-stayed bridges, the Wolkenburg Suspension Bridge serves as an example of a bridge of this kind that, if designed with a good aesthetic taste, can be used for any form of traffic,

 

even if this bridge is open for pedestrians and fishermen only.  😉

Lunzenau Pedestrian Bridge Opens to Traffic

luzenau1
Lunzernau Bridge in the final stages of construction. Photos taken in March 2017

One-of-a-kind bridge replaces a two-span bowstring arch bridge and re-establishes connection in small village in Saxony.

LUNZENAU/ GLAUCHAU- During my bike tour along the Zwickauer Mulde this year, I was greeted with new bridges that had replaced structures that were, on the one hand, damaged by flooding, but on the other hand, appeared bland and needed a makeover. After the Wernsdorf Wave near Glauchau, another bridge is making its debut, but one that restores a key connection in a small community that is nestled in a deep river valley and provides various recreational possibilities.

 

Enter the Lunzenau Pedestrian Bridge, also known to locals as Küblers Bridge.

 

This bridge is located on the north end of the town of Luzenau, just off the Mulde Bike Trail, located at Schaisdorfer Flur near Eichelberg.  Biking past the bridge back in March, the bridge was already installed in place and in the final stages of completion, which included constructing the approaches and adding lighting to the deck. Since 22 June, the bridge is now in use for pedestrians and cyclists, thus restoring a vital connection between Friedrichstraße where a couple factories had once stood, and Burgstädter Straße and the park and sports complex on the opposite end.

luzenau3
Close-up of the truss span and wingwalls

The two-span, 75 meter bridge replaced a two-span bowstring through arch bridge that was built in 1889 and was christened the “Augustus-Johanna-Brücke,” named after the royal couple in Saxony at that time. The bridge was dedicated on 13 July that year and provided access to the factories located at Schaisdorfer Flur, where Friedrichstraße is now located. The structure had a Parker truss design with pinned and welded connections. The endposts were vertical- a rarity for bowstring Parker designs. The portal bracings consisted of a beam bent into a trapezoidal fashion, yet the struts have straight beams with 50° heel bracings. Despite being rehabilitated in the 1950s, the bridge had maintained its original form and continued use until it was damaged by floodwaters in 2013 and subsequentially condemned in December 2014. After securing funding for the project in May 2015, the contract was given in December that same year and in January, the project began with the removal of the truss spans with the crane and the demolition of the eastern approach spans and abutments. This was followed by rehabilitating the center pier and adding a new concrete foundation at the top to anchor the new spans at the center. The new approaches and abutments were built at the same time. In January of this year, the new spans were brought in by truck and installed with the crane. During my visit in March, the roadway had already been installed, as workers took advantage of the unseasonably warm weather and tried finishing ahead of schedule.

luzenau2
Close-up of the V-shaped towers and restored stone pier.

In terms of the bridge’s appearance, the structure, painted in red (trusses), white (railings) and blue (tower), is a real eye-opener that will surely become one of the town’s key landmarks. The bridge is a cantilever pony truss bridge, designed as a Warren truss, but having one tower, planted in the middle of the river, supporting the two spans that each extend to the abutments on the river bank. Its tower is V-shaped, extending outwards. The bridge had welded connections as the tubular steel beams were assembled together at the bridge-building firm before being carried to the bridge site by truck and put together by cranes.  The bridge’s design follows the examples of two bridges: the towers mimic those of the three cable-stayed bridges being installed in New York City; the cantilever truss follows closely to the Paradiesbrücke, a more ornamental but almost 120-year old structure that spans the same river but located upstream in Zwickau.  With the Lunzenau Bridge in service, we have two one-tower cantilever Warren truss bridges along the Zwickauer Mulde- a rarity in Europe and even North America- but the newer bridge is sleak and really colorful, an attraction that will get many bikers and pedestrians to stop by to pay a visit.

The dedication ceremony was met with very positive feedback as dozens gathered to cross this new bridge. This included members from the construction company that built the bridge, from the District Mittelsachsen, Mayor Ronny Hofmann and even Pastor Gerd Flessing who oversees the local church. “Without the funding, careful planning and participation of everyone in this project, this project would never have been realized,” said Hofmann in an interview with the Chemnitz Free Press. “This bridge is a real jewel and I’m thankful everyone had a chance to be involved in this.” That comment is completely true in that aspect. Those who chimed in on the structure got themselves a real gem that will be up for many awards for its design. The bridge will indeed gain from all who have seen it and recommended it to others.

 

This goes beyond my impressions of the bridge and my providing support for the town for this fine work. 🙂

Vital link between Wernsdorf and Glauchau Restored with one of the most unique crossings along the Zwickauer Mulde

bhc newsflyer new

GLAUCHAU (SAXONY)- The closing of the link between Glauchau and Mosel via Wernsdorf because of a bridge that was no longer usable due to flood damage was a hindrance for bikers using the Mulde Bike Trail. Construction of the bridge, which included the bridge’s removal took longer than expected due to unfavorable weather conditions and the reconstruction of the bike trail approaching the bridge. Despite all the complaints and confusion, even at the grand opening, the wait was worth it.

Dozens of people gathered on June 20 at the grand opening of the Wernsdorf Wave Bridge. The bridge spans the Zwickauer Mulde, approximately a half a kilometer west of the village of Wernsdorf, and three kilometers south of Glauchau. This is the third crossing in its history at the site, but one whose aesthetical value will cause bikers and bridge-lovers to stop for a break or even a photo opportunity. The bridge features a three-span suspension bridge, but one that is unlike any suspension bridge built to standards. The roadway is draped over the pylons, creating a wave-like setting when crossing the structure. Only a handful of these bridges exist in Germany, the nearest example being the Dragon Tail Bridge near Ronneburg, 30 kilometers west of Glauchau in eastern Thuringia.

From the top of the pylon to the bottommost part of the dip has a height difference of up to 2 meters. The entire length of the bridge is 110 meters with the width of the roadway being 5 meters. Because of the dimensions, no cars or other motorized vehicles are allowed to cross, which has caused some dismay for those wishing to access the neighboring towns of Dennheritz and Schlunzig, among them, seniors ages 65 and over, which represents the majority of the population of Wernsdorf and Dennheritz as well as nearly half of Glauchau’s population.

Yet despite this, having the Wernsdorf Wave Bridge will mean that cyclists will no longer have to share the road with automobile drivers between Schlunzig and Glauchau, especially in areas in and around the Reservior, where a lot of recreational activities are taking place during the summer, including swimming, hiking and many forms of sports activities including soccer. Furthermore, with the construction of the new Mulde crossing at Schlunzig, car drivers will have better access between Dennheritz and Wernsdorf, and places in the southern end of Glauchau. This is probably the reason behind the decision of Glauchau’s mayor Peter Dresler to designate the Wave Bridge for bikes, walkers and even equestrians!

But while that plan for autos is in the making, people driving past Wernsdorf will have a chance to see an attraction which is hoped will become one of the key signatures of not only Glauchau and Wernsdorf, but also along the Mulde. With the Wave Bridge being the third crossing open this year behind one at Lunzernau (near Penig) and Wolkenburg, the Mulde Bike Trail will have three new bridges in use, each one presenting a unique design that will not only cause many to stop and awe, but will change the landscape of the ccommunities they serve. The Wernsdorf Wave Bridge is one that brings three communities together, even if it is for recreational use. 😉
