Floating Bridge in China

Most recently, one of the followers on my Twitter page posted a gif-pic of this bridge. This is located in China, spanning a very deep gorge. Obviously the bridge is a pontoon otherwise it would not be spanning a river that forms this gorgeous gorge. But the way the car crosses creates a wavy scenery that can be experienced from each vantage point, even from inside the car. Enjoy this short clip and if you want to help, tell us about the bridge and where in China it is located. Surely there will be more bridge enthusiasts who will pay homage to this unique structure while visiting other interesting places in China, from the Great Wall to Shanghai, Hong Kong to the Himalayans.

HONG KONG/ MACAU/ ZHUHAI (CHINA)- The idea took 35 years to bear fruit. It took nine years to build. And the idea came from the Chesapeake Bay Bridge and Tunnel. Now the 55 kilometer bridge is open, connecting Hong Kong  on one end and Zhuhai (China) and Macau on the other.  The HMZ Bridge was dedicated to traffic today, with over 700 officials attending the ribbon-cutting ceremony that would allow traffic to cross the bridge for the first time ever.  Consisting of three different cable-stayed suspension bridges, over 29 kilometers of main bridge spans and 6.7 kilometers of undersea tunnel, plus the remaining kilometers for approach spans, this bridge provides direct access to Hong Kong’s International Airport, the city itself and Lantau Island from Mainland China, built at a cost of over 20 billion Euros (or $30 billion).  Instead of three hours, travelers can expect to reach their destination in about 30 minutes. A feat that will surely stand for all time to come.  🙂

To better understand the importance of the bridge and what it looks like, a pair of documentaries are available for you to view.  One of which is an ariel view of the bridge. Another is a 20-minute documentary by a Chinese TV network which takes you across the bridge and provides you with some interesting facts about the bridge.

Before going further, let’s have a look at the longest piece of architectural landmark in mankind history 🙂 :

2017 Author’s Choice Awards- Author chooses his best and worst- albeit belatedly

Lakewood Park Truss Bridge, relocated to the middle school in Salina, KS.  Best Example of a Restored HB according to the author.  Photo taken by Jack Schmidt

After a very long delay due to bridge and non-bridge related commitments that needed to be address, it is long past overdue to present the Author’s Choice Awards for 2017. Normally this would have been awarded at the same time as the winners of the Ammann Awards (see the results here). However there were some developments bridgewise that kept me from posting the results. By the time the opportunity came to do that, commitments related to my other job as teacher pushed the posting back much further. Yet, better late than never to announce my pics for 2017, with a promise to be more punctual when I announce the 2018 Author’s Choice Awards in January 2019, the same time as the winners of the 2018 Ammann Awards that will be announced simultaneously.

So without further ado, here we go…..

2017 was an exceptionally hard year for historic bridges for dozens of them worldwide were destroyed either by mother nature in the form of wildfires, flash flooding and other storms or through really unintelligent people ignoring the weight and height restrictions for the purpose of convenience and shortcuts. With the second part we will get to later. Let’s look at my picks for 2017 as the bridges deserve the author choice for the following reasons:

Best Find of a Historic Bridge:

USA: 

While my pics go directly to the state where the government is trying profusely to destroy every single metal truss bridge in the state- namely New Hampshire, two areas with a set of historic bridges deserve to be recognized here. The first one are the bridges of Hinsdale/ Battleboro There, we have a pair of Pennsylvania through truss spans in the Anna Hunt Marsh and the Charles Dana, the Killburn Brook Stone Arch Bridge, the Chesterfield Arch Bridges and a pair of railroad bridges. A tour guide will be made soon as two of the bridges face uncertain futures for even though a replacement bridge is being built on a new alignment downstream, the public is divided between restoring the truss spans and simply demolishing them. One of the proponents of the latter had already defaced the Anna Marsh bridge by removing the planking and appears to be grabbing the city government by the balls to have them fulfill his demands. However, that person is being held at gunpoint by others who disagree.  Michael Quiet produced a pair of videos on the Anna Marsh and Charles Dana spans which you can see here:

Runner-up is a pair of former railroad truss bridges located at Pulp Mill. The older truss span is an 1868 Whipple through truss with vertical endposts featuring Phoenix columns. The 1921 truss is a pin-connected Pratt through truss bridge. While both are abandoned, they deserve a second life as a bike crossing, don’t you agree?  The two bridges received the bronze medal in the Ammann Awards competition under Bridge of the Year.

       International:

Since the beginning of 2017, I had the priviledge to do a bridgehunting tour along the Zwickau Mulde River in the western part of the German state of Saxony. 200 kilometers and consisting of some of the Ammann Award winners of Zwickau, Glauchau, Aue and Rochlitz, plus some candidates in the Lunzenau area, the river region features a tall 150-year old concrete viaduct, several stone arch bridges, big and small, a handful of pre-1930s era truss bridges as well as cantilever and Suspension bridges. All of them are accessible via Mulde bike Trail and if Things go the way the Mayors of Glauchau, Rochlitz and Lunzenau want it to be, the former railroad line connecting Glauchau and Wurzen that runs parallel to the Zwickau Mulde may end up becoming either a Tourist rail line or a “rails-to-trails” route in the next five years. For that reason it deserves the Author’s Choice Awards as a way of motivating them to make this Project happen.

Best Example of Preserved and Reused Historic Bridge:

USA:

Lakewood Park Truss Bridge. Built in 1877 by the Missouri Valley Bridge and Iron Works Company and measured at 99.1 feet Long, this pin-connected Pratt through truss Bridge with Town Lattice Portal bracings was relocated to ist present site, which is the Lakewood Middle School in Salina, Kansas, a few blocks from where it had been originally located. The Bridge serves as living history and a park area for students wishing to relax and learn some history about the structure and ist Connection with Engineering history in the US. The Bridge Looks just like new with ist decking and benches. It is definitely worth a visit and for sure receiving this Award.

International:

While this Bridge received third place in the Ammann Awards under the category Best Example of a Restored Historic Bridge, the Ponte Pensil Sao Vicente Suspension Bridge near Santos, Brazil is getting the Author’s Choice Awards for its in-kind restoration of the Suspension Bridge, with new decking and cables, but being able to retain ist structural integrity. This was a masterpiece that is worth the recognition. The Suspension Bridge can now carry vehicles and pedestrians across the river without the fear of collapse.

Most Spectacular Bridge Disasters

USA:

Mother nature has not been kind to mankind this year and has shown ist distaste because of the ignorance of the effects of industrialization, wasting non-renewable resources and too many cars and housing. This includes massive forest fires, die-offs of fish, and especially widespread flash-flooding. For this year’s most Spectacular Bridge Disaster Story, we have two examples from the US, one of which Mother Nature redid a piece of artwork that was perceived as wrong.

The James Bridge in Ozark County was one of four key bridges that were wiped out by flash-floods during the first weekend of May, which also took out the Hammond Mills and Bruns Bridges– the former of which was only 30 years old and a concrete slab bridge; the latter a 130-year-old historic truss bridge. The James Bridge featured a two-span polygonal Warren pony truss bridge with riveted connections that was built in 1958. The flood not only knocked it off ist foundations but it flipped over upside down, thus converting the span into a deck truss. Workers removing the “makeshift deck truss bridge” as well as reporters on the scene were quite impressed with the artwork Mother Nature had left behind as a result. Yet this is the second time in six years this conversion from a pony truss into a deck truss has happened- all in Missouri.

The runner-up was a tight one between another bridge collapse due to flooding and mudslides in California, and this bridge in Atlanta, the I-85 Bridge. This structure fell victim to a blazing inferno on 30 March, causing a 28 meter (92 foot) section to collapse. Investigators later concluded that a combination of improper storage of materials underneath the concrete viaduct and arson resulted in this unfortunate event. Still, this disaster became the new Minneapolis Bridge disaster, for the collapse showed that even potentially dangerous flaws in concrete beam bridges can exist.

 

International:

There were over a dozen well-known bridge disasters in Europe and Africa in 2017, yet there are two stories that stand out and deserve recognition.

The first place winner goes to a bridge in the Indian state of Goa. There, a Whipple pony truss bridge spanning the River Sanvordem at Curchorem collapsed under the weight of people on 18 May. Official reports put the casualty totals of two dead, dozens injured and 30 people missing; many of those missing were presumed dead as the river was infested with crocodiles, which made rescue attempts difficult. Spectators had been on the bridge to watch efforts to rescue someone who wanted to commit suicide by jumping off the bridge. The bridge goes back to the 1800s during the time the Portuguese had control of the Goa Region. As of right now, the bridge, abandoned for many years, is scheduled to be removed. This is the second bridge disaster in two years that included the Goa Region.

The runner-up in this category is the collapse of the Troja Bridge. This bridge goes back to the Communist era and used to span the River Vlatava near the Zoo in Prague. On 2 December, the entire concrete beam structure collapsed, injuring four- two of them seriously. The causes of the collapse stemmed from age and structural deficiency to its weakening as a result of the Great Flood of 2002, forcing officials to monitor the bridge more closely while introducing plans to replace it with a newer, more stable structure.

Biggest Bonehead Story:

In the final category, we look at the Biggest Bonehead Story and this is where we look at stupid people destroying historic bridges for unjustified reasons. We have a lot of good stories that go along with this topic, all of which in the United States. And with that, we will look at Judge Marilyn Milian, the judge for the TV-series The People’s Court.  Since taking over for Judge Wappner in 2005, Ms. Milian has used her sassy commentary and rhetoric to put people in their places for their actions that are both legally and morally wrong. At the same time, she has a zero-tolerance to people doing stupid things as well as making unintelligent comments, sometimes embarassing them on TV. Some classic examples of how the Lady Judge does her work can be seen here:

Back in January 2018, when the Ammann Award winners were being announced, I tried to contact Ms. Milian to see if and how she would react to the following bridge disasters that were caused by stupidity at its finest- all of which will share the Author’s Choice Award for 2017 because of their bizarre nature. That is, had the courts not decided and the cases had been sent to the People’s Court 😉  :

1. Gilliecie Bridge (aka Murtha and Daley): This 130-foot long bowstring arch bridge, built by the Wrought Iron Bridge Company in 1874, spans the Upper Iowa River at Cattle Creek Road. It had the weight of three tons before the driver of a grain truck, weighing five times as much as the weight allowed on the bridge, tried to cross it on 5th May. After hitting the eastern portal, the truck and the bridge fell right into the water! The driver wasn’t injured. He later claimed that his GPS device led him to the bridge and afraid that he could cause an accident while backing up, he chanced it. Another Mary Laimbright slash “My GPS made me do it” story but sadly unlike the incident and its after-effects at the bridge where she downed it with a semi-truck in 2015, this bridge in Iowa may have seen its last days before being scrapped. Its future is uncertain.

2. Cedar Covered Bridge: Spanning Cedar Creek near Winterset, this bridge was built in 2004 as a replica of the original 1883 span that was destroyed by arson in 2002. This bridge was torched again, this time by three high school teenagers on 15 April, 2017. There, two of them poured gasoline on the decking while the third one set it ablaze. The bridge was left with a charred Town Lattice truss skeleton after the fire was put out. The person who had set the fire to the bridge was upset after breaking up with his girlfriend, with whom he had spent time on the bridge. Before his sentencing in June, the person wanted to get out on bail so that he could graduate from high school. He was later arrested for setting a car ablaze in March in West Des Moines. For the bridge he torched, he received a deferred sentence of 10 years in prison and five years probation. His two other accomplices also received suspended sentences and probation. Yet this incident is a reminder of another incident at McBride Bridge in 1984, which was caused by heartbreak. That person, who destroyed the bridge, had to help with rebuilding the bridge as part of the sentence. Sometimes hard labor helps shape a man.  By the way, the Cedar Bridge is being rebuilt again, for the third time. Opening date remains open.

3. Longwood Lane Pony Truss Bridge: Spanning Cedar Run in Fauquier County, Virginia, this pony truss bridge had a very quiet life until a UPS Delivery Truck crossed it on July 17th- or should I say the driver tried to cross it, but it fell in the water. So much for the delivery, not to mention the job as a delivery person. The fastest sometimes had the worst.

This leads to the question of how Judge Milian would handle this, had she seen these three cases in the People’s Court? Would she handle them like above, or even in a case below? What examples an be used? And who would win the case: the owners of the bridges (all of them had been owned a the county) or the defendant? And if the plaintiff, how much would the defendant have to pay- financially and timewise in jail?

This is where the forum is open to the judge, but also to the followers of the People’s Court. 😉

And this wraps up the 2017 Author’s Choice Awards for some of the most bizarre bridge stories. There will be much more for the 2018 Author’s Choice Awards, as there are enough stories to go around there. They will be posted when the winners of the 2018 Ammann Awards come out in January. This time the author means it when he says it will come very timely next time around. So stay tuned! 🙂

Mystery Bridge Nr. 100: The Bridge at Fischweg in Chemnitz

fischweg

CHEMNITZ (GERMANY)- I’m going to be very honest for this mystery bridge, which is the 100th structure I’ve posted since launching the series in 2011. It was very, VERY difficult to decide which one to post next, for there was a large selection to choose from, ranging from an abandoned bridge along Route 66, a three-span through truss bridge in Oklahoma, a suspension bridge in India and this bridge. After some thorough consideration, I decided to go with the way that is the best in terms of my own merit as the structures have been mentioned by others in one way or another.

So here it comes: a through truss bridge that has been sitting on private land for a very long time, on the outskirts of a city that was for some time named after a Communist. Found by accident but not before almost getting my Volkswagen rammed into by a lorry behind me, who was cussing at me in Polish as he passed me by, after having parked my car off to the side. 😉

fischweg3

OK, the Polish guy part was fake news, but looking at the rest of the picture, one can see that you don’t need to fact-check this beauty.  The bridge is located just off Highway 107, three kilometers north of the Motorway A4 and the Exit Chemnitz-Glösa. It sits on private land next to the restaurant and hotel Landgasthof Draisdorf, around the curve.  It is an eight-panel Pratt through truss bridge, built using welded connections- meaning the beams are held together by gusset plates and are not inserted into the plates, like we would see in other truss bridges. The end posts are typical for many European truss bridges built during its time: vertical instead of angled. The portal and strut bracings feature V-laced bracings with curved heel bracings. The middle strut heels appear to be subdivided.  The bridge can be seen from the highway- although it is not recommended to stop because the highway curves around the Landgasthof and one could risk such a rear- ender plus an explanation with the police to follow.  The bridge is about 5-6 meters tall, about 30-35 meters long and 3 meters wide, judging by my presence at the bridge and the photos I took of the bridge. While the bridge is one of five known in Chemnitz, this is the only through truss bridge within the city limits, counting the village of Draisdorf, where it sits.

The fun part comes with the history of the bridge. My first judgement of the bridge was that it was located over the River Chemnitz at Heinersdorfer Strasse and it was pulled offsite and to its current location after a new bridge was constructed 100 meters to the south. The truss bridge was replaced by a new bridge in 2005.  You can see the points mentioned on the map. However, research by the Saxony Ministry of Historic Monuments and Preservation (D: Landesamt für Denkmalpflege Sachsen) in Dresden indicated that this truss bridge was not originally located at Heinersdorfer Strasse but at Fischweg near the cemetary in Glösa, only 400 meters south of the motorway exit. The map indicates that a bridge does exist but in a form of a bike and pedestrian crossing for the street ends on the grounds of a factory nearby. The date of construction of the bridge is 1900 and is currently listed in the Preservation Handbook for the State of Saxony (Denkmalschutzliste).

This leads us to the following questions which your help would be much appreciated in contributing whatever information may be of use:

  1. Is the date 1900 correct? Sometimes the year is used because of a lack of clarity in terms of when exactly it was built and open to traffic.
  2. If the bridge was not originally located at Heinersdorfer Strasse, what did the previous structure look like? When was it built and was it built by the same bridge builder as this bridge?
  3. Independent of what was mentioned in nr. 2, who was the bridge builder for this bridge?
  4. When was the current structure at Heinersdorfer Strasse built and what happened to the old structure?
  5. What factors led to the replacement of this bridge and who led the efforts in saving it for reuse?

fischweg2

It’s not every day that a person and/or party steps forward to purchase the bridge and keep it for reuse. The bridge is privately owned and judging by my observations, it is being used as a picnic area with a porch swing attached to the top strut bracing. For most historic bridges that are purchased by private groups-namely homeowners, they are normally used for picnic areas and other forms of recreation more than for pedestrian and bike crossings because of liability reasons. It is different in comparison with private parties in the form of associations, park and recreational groups and the community that have more resources (including financial) to make sure the crossing is safe for reuse. But nevertheless, this bridge is safe and will most likely be in the hands of the homeowner until the need to get rid of it is near. When that happens, it can be hoped that the bridge is put back over the Chemnitz as a bike crossing. With the Chemnitztal Bike Path being extended and paved to Wechselburg, it would not be a surprise if this bridge was called to duty again given its preservation status and the interest in keeping it for generations to come.

And this is what makes this unexpected stop the most memorable- finding out the unknown about a structure like this one, which is truly a hidden gem.

And as we are on the same page, the next mystery bridge will go further downstream where a pair of structures are being refitted for bike use. More on this one in the next article. In the meantime, enjoy the photos here as well as on BHC’s facebook page.  And as for the aforementioned bridges at the beginning of the page, they will come later.

 

Author’s Note: Chemnitz was once named Karl-Marx-Stadt when it was under the rule of the German Democratic Republic. It even had a head statue of Karl Marx that can still be seen today. From 1953 until 1990, it was known that way.

Triple Whipple Bridge in Dearborn, County, Indiana

064361pv
HABS/HAER

Our next bridge profile is a true rarity found in the US; in particular, in one of the most historic bridge-laden states in the country- Indiana. Three miles south of Aurora in Dearborn County, and a half mile west of the Ohio River is the Triple Whipple Bridge. The origin of the name comes from the fact that this 298 foot long through truss bridge is the only truss bridge of its kind left in the United States, whose diagonal beams pass through three panels instead of the two that are typical of the truss design invented by Squire Whipple. Normally, truss bridges have diagonals supporting one panel. The bridge was built in 1878 by the Wrought Iron Bridge Company and used to serve a major highway until the 1950s. Restored in 2008, it still receives its lion’s share of pedestrians and cyclists today.  It has been on the National Register of Historic Places since 1978.

A while back, History in Your Backyard did a documentary on this bridge, which includes an in-depth coverage of its history, let alone a detailed view of the bridge, both ariel as well as on the ground. Before explaining further about this bridge, one should have a look at the film and plan a visit. A map with the bridge’s location is at the end of this article.  Tell us about your impressions of the structure. Recommend it to others, even if they are passing through. There you will see a prime example of how Indiana takes care of its artefacts for others to see while stopping by. Enjoy! 🙂

The Bridges of Markersbach (Saxony), Germany

IMGP1518

There is a proverb that I’ve been going by while bridgehunting recently, especially in the eastern part of Germany: The smaller the community the more historic bridges one can find. While cities, like Chemnitz and Zwickau have numerous bridges, the number of century+ old structures are relatively small in terms of numbers and ratio compared to modern bridges, smaller towns like Glauchau, Aue and even Rochlitz have a higher number of historic bridges. The trend is similar in many small cities and towns in Europe which makes finding historic bridges much easier. Yet when a person finds such a small community that has an important historic bridge, like you are about to read about here, chances are more likely that the person will find more than what they bargained for in terms of finding other structures that are just as significant as the town’s centerpiece.

And this is where the tour takes us back to the Ore Mountains but this time, a bit further east of Aue by about 15 kilometers to a town called Markersbach. With a population of only 1600, the town lies deep in the valley of the Bigger Mitweida Creek, which effectively cuts the community and its neighbor Rauschau into two. First mentioned in the history books in 1210, it was part of the Cisterician Monestary and later the Peter and Paul. The Church of St. Barbara, built in 1610, is one of the oldest churches in the mountain regions. The water pump power plant is located at the upper basin of the Mitweida serves the region. The Jenaplan School, based on the concept created by Peter Petersen in the 1920s, is located in Markersbach but the community school’s origins dates back to the 1500s.  Since 2007, Markersbach is a joint-community with neighboring Raschau, which has as many people as its neighbor. The city is served by a major highway connecting Schwarzenberg and Aue to the west and Annaberg-Buchholz to the east. A railroad line connecting Schwarzenberg and Annaberg rarely provides service.

And the centerpiece surrounding the community is also the highest viaduct in the region, the Markersbach Viaduct, nicknamed as the Matchstick Bridge, for the structure was built using thin but heavy steel parts.  The bridge was the primary reason for my visit. However arriving there, I found three more significant railroad bridges, a few smaller bridges that are at least 70 years old, a highway viaduct that somewhat fits into the landscape with its color.  That means five major bridges and a couple smaller stone arch bridges can be seen as one travels along the main street that runs parallel to the Bigger Mittweida. This large number of bridges was one of the factors in having a bridge festival in 2010, which included a tour of the viaducts by train and fireworks.

Yet given the number of houses and trees that are skewing the view of the bridges, combined with a lack of parking with the car, it is rather difficult to get to the structures without asking the property owners to climb onto the rooves of their houses just to get a good shot of the bridge. Or stand in the middle of the street ensuring one doesn’t get hit from behind by a car.

This tour will look at the bridges in Markersbach, beginning with the centerpiece, for it symbolizes the community’s history and existence, followed by the less mentioned ones but also have some charm to it. The information is scarce for all but the Matchstick Bridge and therefore will be updated as more people step up with their stories and facts about the bridges. One has to keep in mind that Markersbach can be easily passed over, thanks to the new viaduct (a.k.a. The Flyover) that has been in service for over seven years. Therefore before entering the viaduct, one has to turn off: to the right and down the hill past the loop before seeing the first bridge; to the left there is the grand view of…..

IMGP1524

this viaduct!

Markersbach Viaduct:

The Markersbach Viaduct is one of the key historic bridges in Saxony one needs to visit. The viaduct spans one of the tributaries that empties into the Bigger Mitweida. With a total length of 236.5 meters and a height of 36.5 meters, the viaduct is the tallest of its kind in the Ore Mountain region. Under the direction of bridge engineer Claus Koepke and built using steel manufactured by the Queen Marie Steel in Cainsdorf (near Zwickau), construction of the bridge took two years, with the completion being 1889, coinciding with the opening of the Schwarzenberg-Annaberg rail line. The line provided train traffic all the way to Leipzig and Berlin until World War II. It was later reduced to Zwickau and then later to Aue. The line no longer serves regular traffic but has special services that provides tourists with a splendid view of Markersbach, the valley and the mountain areas surrounding them. The bridge features nine spans supported by eight trapezoidal towers with X-laced framing. The spans are lenticular deck trusses, whereby the longest spans (two) have curved Warren trusses with 25m each, three 20m spans have polygonal Warren trusses and four 12.5 meter spans have camelback Warren trusses. For each truss type are the triangular panels subdivided. Photos of the viaduct are difficult to do due to the obstruction by the houses. Even getting up close to the bridge is difficult because it requires walking up narrow and winding streets, all but a couple of which are cul-de-sacs occupied by houses and cars. Getting to the opposite side of the viaduct is possible but only through walking through fields and forests. And even then it is hard to come by- one has to be lucky to get up close and personal with the bridge. However a grand view of the entire bridge can be found off the highway at the intersection where the bridge bypass and the road leading to Markersbach meet. That impromtu observation platform is nothing more than a road that used to enter Markersbach before the bypass and the highway viaduct were built.

Highway 101 Flyover Viaduct

In 2005, construction began to construct a nearly 2 km bypass to alleviate traffic going into and through Markersbach. The plan: To construct a tall viaduct which would not only “fly” over the community crossing the Mitweida Valley, but it would also make travel between Annaberg and Schwarzenberg much smoother, especially for trucks. Furthermore, it would provide passers-by with a splendid view of Markersbach, its prized viaduct and much of the mountain while driving “in the air.” 😉  The project was not easy as erosion, causing mudslides hindered consturction, the worst having occurred on the eastern slope in October 2006. The next problem was establishing a firm foundation for the pylons, which was discovered the following July.  When the bridge finally opened in November 2011, it was four years behind schedule. However, the delay was worth it for the jeans-blue steel deck girder with cantilever features now hovers the community and its valley, narrowly surpassing the railroad viaduct by only 7.5 meters. The Flyover is 317 meters long and has two lanes totalling 25 meters. The cost for the project: 25 million Euros, twice as much as previously planned. Yet the Flyover is still most travelled today giving residents a piece of mind without having to worry about their children running across the street and risk getting hit by trucks and racing cars.

Mitweidathal Viaduct:

When entering Markersbach by turning off at the Flyover, one will be driving down the hill along the winding stretch of what was Highway 101 (German: B101), flanked by trees on both sides. Yet at at the loop where one crosses the Mitweida Creek, one enters the community, greeted by houses on both sides of the street and this bridge. One should not be fooled by its appearance. It is definitely not the Markersbach Viaduct because of its height. One can even see the difference from a distance- either at the observation point at the Flyover or even along the former highway on the left entering town. The Mittweidathal Viaduct is shorter in length but it is not just simply a bridge, whose characteristics are its curve towards the Markersbach Viaduct as well as its brick piers. When looking closely at the 86 meter long and 10 meter high viaduct, it features brick piers with quarzite-like stripes and six spans, each one featuring a deck plate girder supported by polygonal Vierendeel trusses. Because of the absence of diagonal beams they are not Parker trusses, yet they have an appearance of a lenticular truss. So to categorize the truss style, it is considered a half-lenticular polygonal Vierendeel truss with welded connections. The bridge has existed as long as the rail line itself. Yet because of its seldom use, age caused by weather extremities has taken its toll. Should the line be used again, either as train service or as a bike trail, some repairs will be needed to ensure the bridge continues to function in its original form.

St. Barbara/ Annaberg Street Viaduct:

About 400 meters away from the Mitweida Viaduct and following the former highway through Markersbach is this viaduct. The St. Barbara Viaduct was named after the nearby church- the oldest one in Markersbach- which is located on the same street as the viaduct crosses: Annaberg Street. The 70-meter long viaduct features four spans of deck plate girders, the longest is 30 meters and features a Camelback girder design which hovers over a side street that is opposite Abrahamsbach Creek) and runs pararell to Annaberg Street. Where that span crosses is near houses that line up along two sharp curves, which is dangerous for all vehicles.  The viaduct looks like one of the newer spans that had replaced a previous bridge, but it is unknown when the replacement date was. We know that the bridge is 200 meters away from the Markersbach Viaduct and is located near some key points in the community: the afreoemntioned church, a Methodist Church, a park and the Jenaplan School. Even though the viaduct is seldomly used today, a curious question I have is how people tolerated living right next to the viaduct, especially during Sunday mass at church? 😉

Raschau Viaduct:

The last bridge on the tour takes us one kilometer west to neighboring Raschau and this bridge, the Raschau Viaduct. Like the Markersbach Viaduct, the Raschau Viaduct is the most original of the bridges profiled here, as the bridge dates back to the construction of the rail line. This is especially noticeable as the seven-span viaduct, built on stone piers, features Town Lattice deck trusses, built using welded connections and a thick network of diagonal beams both in the inner and outer portions of the spans. The bridge has a total length of 112 meters, making it the second longest crossing along the Schwarzenberg-Annaberg rail line. The width is 12 meters. The height above the streets is four meters, making it the lowest crossing above ground level along the line as well. Height restrictions have been enforced to discourage truck drivers from using the streets. With the Flyover, combined with access on both ends of Markersbach and Raschau, the bridge has not sustained any damage, even though German laws have also played a role in forbidding overweight and oversized vehicles from using the road. Had this bridge been located in the States, with its lack of laws forbidding such vehicles, the Raschau Viaduct would not have survived such careless driving, and the driver would most likely have been forced to pay for a new bridge. However, because of its conformity to the landscape and its beauty, this viaduct will most likely remain for a long time.

There are a few single-span arch bridges but with the exception of a railroad overpass, these structures are only short spans and are difficult to photograph. A couple points of interest are worth photgraphing, which are noted in the Google Map. The bridges presented in this tour guide are examples of structures that represent a small community, whose history play a role in establishing the community and bringing it together. And while all but one are seldomly used today, the bridges at Markersbach are indeed diamonds in the rough, which is worth a couple hours of visiting and taking some photos. Even more so if the community has bridge festivals and other local celebrations throughout the year. 🙂

2017 Ammann Award Results: Part 1

New Olympic-Style Medal System to the Top Six Finishers

Record Number of Voter Participation

SCHNEEBERG (SAXONY), GERMANY- 2018 is here, and with it, the revealing of the winners of the 2017 Othmar H. Ammann Awards. This year’s awards ceremony is far different than in years’ past. For instance, instead of announcing the winners in nummerical order from top to bottom, the top six winners receive a medal in a combination of Olympics and Ore Mountain form. That means the top three finishers receive the typical Olympic medals, whereas 4th to 6th place finishers receive medals typical of the Ore Mountain region in Saxony in eastern Germany, the new home for this column (specifically, in Schneeberg). That means tourquoise, copper and iron ore to those respective finishers. To view the total number of candidates please click here for details, including how they finished.

This year’s awards set some impressive records that can only be bested by more participation and more awareness of the historic bridges that we have left in general. For instance, we had records smashed for the highest number of voter turnout in each of the nine categories. Furthermore, there were at least seven lead changes in each category, which was also a first. In four of the categories, there were lead changes with at least four of the candidates. In another category, each of the candidates took a shot at first place and stayed at the top for at least a week before it was dethroned in favor of another one. In summary, no leader was safe regardless of margin that was built with its second place competitor. 🙂

And with that we will take a look at the winners of the 2017 Ammann Awards, divided up into two parts so that the readers are not overwhelmed with the content. The winners of the 2017 Author’s Choice, where the author himself picks his favorites, will follow. But for now, let’s see what the voters have chosen for bridge favorites beginning with…..

 

BEST PHOTO:

This year’s Best Photo Category brought in not only double the number of candidates as last year (12 entries) but also double as many candidates that vied for first place as last year- there was a battle among three candidates for the top spot for the 2016 Awards. All six candidates finished in the top six with Chauncy Neumann bringing home the gold for his night photo of the Rock Island Railroad Bridge in Little Rock, AR., a fine example of a rail-to-trail crossing that still has its use in its second life today. His photo can be seen in the Chronicles’ facebook page as well as an avatar for the Chronicles’ twitter page. The silver medal went to Esko Räntilla for his stone arch bridge, built in the 1700s spanning a small creek in Finnland. That photo can be seen in the Chronicles’ wordpress page. Third place finisher receiving the bronze was Kevin Skow for his shot of the pony truss bridge Mill Creek in Kansas. His photo can be seen on the Chronicles’ twitter page. All of them will remain to be seen until mid-July before they become part of the header rotating page for the Chronicles’ wordpress page. The rest of the results:

Draschwitz Bridge north of Zeitz in the German state of Saxony-Anhalt: Winner of the Best Kept Secret International Award

BEST KEPT SECRET INDIVIDUAL BRIDGE:

This category is divided up into American and International Bridges and focuses on historic and unique bridges that receive little to no attention compared to other historic bridges, like the Golden Gate and Brooklyn Bridges in the States. In the international part of the category, we had 14 entries from three continents with four vying for the top spot. In the end, the winner of award goes to a small village north of Zeitz in Germany and this unusual bridge, the Draschwitz Truss Bridge over the White Elster River. This bridge is unique because of its v-laced top chord. The story behind it can be found here. Silver goes to the suspension bridge at Betsiboka in Madagascar, whereas Bronze goes to another unique arch bridge in Greece nominated by Inge Kanakaris-Wirtl, the Plakidas Bridge. The rest of the top six include:

In the States, we had ten entries, featuring bridges from all over the country. This included a “dead bridge”- one that has been extant for many years, yet one decided to nominate it post humously. As in the international portion, four of the ten vied for the top spot, but in the end, the Sarto Bridge, spanning the Bayou des Glaises at Big BendAvoyelles Parish, Louisiana came out the winner by a slim margin, outlasting the Johnson Bridge in Stillwater County (Montana) by five votes. That “dead bridge” mentioned earlier, was Sugar Island Bridge in Kankakee Illinois, came in third with 88 votes- a bronze medal well earned a century after it was converted into a pile of scrap metal. The bridge was destroyed by a tornado in 1916 and was replaced afterwards.  The rest of the top six include:

MYSTERY BRIDGE:

Twelve bridges were entered in this category, of which three came from the States and the rest from Germany. Still, the winners of both the international and American competition were clearly decisive with the American bridge winning the all around by a wide margin. That was with the Geneva Creek Bridge in Muscatine, Iowa, a Bedstead Howe pony truss that features two spans and was relocated at an unknown time. Information on that is enclosed here. The ancient arch bridge in Erfurt won the international division but came in second in the all around. That bridge spans a small waterfall that empties into the Diversion Channel on the south end of the city in Thuringia. It may be the oldest extant structure in the city’s history. For more, click here. Not far behind was another competitor from the German state of Schleswig-Holstein, a thatched-roof covered truss bridge in St. Peter-Ording, whose unique story can be found here. The rest of the standings include:
