1980s era bridge to be torn down because of fire damage despite having been rehabilitated. Fire under investigation.

bhc newsflyer new

FLÖHA (SAXONY), GERMANY- Approximately 13 kilometers east of Chemnitz in the district of Mittelsachsen is the town of Flöha. With a population of 10,130 inhabitants, the city is located at the junction of the River Zschopau and the River Flöha and is loaded with dozens of historic bridges within the radius of 5 kilometers. This includes the Hetzdorf Viaduct, which is to the south and east of the city and used to carry the Dresden-Zwickau-Hof-Nuremberg Magistral Railroad.

One of the bridges that used to serve Flöha was the Apfelsinebrücke. Literally translated as the Orange Bridge because of its original color, the bridge was built in 1983, spanning the River Zschopau at Baumwolle Park and having served pedestrians for three decades. The bridge was recently rehabilitated at the cost of 223,000 Euros (ca. $260,000) as it was one of the last structures to have been damaged by floodwaters in 2013.

Sadly though, the steel deck plate girder is coming down- victim of a fire, which has caused anger among the city council members in Flöha and has gotten police and criminal investigators involved as to finding out what happened to the bridge. According to information by the Chemnitz Free Press and supported by German public channel MDR,  the fire broke out on the bridge on Friday at around 3:00pm, sending smoke up to 500 meters high, making it visible to as far west as Chemnitz. Because of its thickness and wind, residents were ordered to keep all windows and forms of ventilation closed until the fire was under control. Fire crews from Flöha and nearby Falkenau battled the blaze for over an hour, which caused telephone lines to go dead as well as power outage to houses nearby due to wiring going across the bridge. When the fire was finally put out, the spans had partially collapsed. “The fire has bent the steel to a point that the bridge cannot be saved,” says  Volker Holuscha , the mayor of Flöha during an interview with the Free Press. Given the extensive damage of the fire, especially because of high temperature caused by the flame, the incident is being investigated. In the meantime, the city is seeking a plan to replace the structure as soon as possible and will be removing the bridge once the investigation is finished. The fire spells a tragic end to a structure that was loved by many locals in Flöha, especially as the city had spent money to keep it in place for generations to come. Now the fire has burned the project up in smoke. It can only be hoped that a newer bridge that will come will be sturdier and better secured to ensure such a fire will never happen again……

U-BAHN Bridge over the River Danube.

A post shared by bridgehunters_chronicles2010 (@bridgehunters_chronicles17) on

I just visited Vienna recently with my family and was very impressed with the city, its clean living conditions, the people there, the architecture, the history and in particular, the bridges. Over 200 bridges can be found in the capital of Austria, some spanning smaller rivers and streams, others spanning railroads, and especially those that span the Danube River, the longest river in Europe which cuts through the metropolis of 2 million inhabitants. While a short guide on the bridges will come soon. Here’s a sneak preview of one of the spans ober the Danube. This cable-stayed suspension bridge was built in 1997 and carries the subway route 2, going alongside a railroad bridge located only 200 meters away. This was taken while on the boat tour along the Danube.

There will be more of these to come here, but you can check out the pics that were posted on the BHC’s Instagram page. Just click here and enjoy!

Have a good one, People! 🙂

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! 🙂

The Rehab of the Hirschgrundbrücke in Glauchau: A Wine Glass Half-full or Half-Empty?

GLAUCHAU (SAXONY), GERMANY- The construction projects in and around the Castle Complex in Glauchau, which has been in motion since April (as a whole), is like eating in an exclusive restaurant: No matter what the menu offers, including drinks, there’s a lot to eat and a lot to discuss at the table.   The main course, which features lamb chops, is the front yard that leads to the gates of the castle. This is the meat of the project which one will find to the south of the city center, just a three minute walk from Market Square. This was once filled with lucious trees and bushes but also home to the ice skating rink that had occupied the area; it is being torn up in favor of a multi-complex featuring picnic areas, a pavilion and bike racks. This despite opposition from those who preferred to keep the area all green and in its natural form. A comment by one of the opponents, an architect, during a conversation on facebook recently, says it all.

Then we have the natural bridge, crossing the deep ravine connecting the castle’s south side and its adjacent park, sitting idle for many years, closed to all because of safety reasons and now blocked off to the castle park. This stone arch crossing is no more except for the pylons and the outer arches!

32722985_1888042357893071_8512619425415823360_o

The Hirschgrundbrücke has been the “vegetarian” main dish for dinner and conversation for many years for many reasons: 1. How to renovate the bridge after sitting idle for 40 years, 2. What is the real name of the bridge: Hirschgrund or Hirschgraben, and now this: Is this bridge a complete renovation/ rehabilitation or a complete tear-down and rebuild?

There are many ways of describing how the bridge is being put under the knife. Yet to better understand how this project is being carried out, I had a chance to talk to the city engineer who showed me the plans of rebuilding the structure during my frequent visits to the City Administration Building. He was also the engineer in charge of overseeing the design and construction of The Wave near Wernsdorf in 2017.  During my interview in March, he mentioned that the bridge was going to be stripped down to the bare bones, leaving the outer arches and the stem of the pylon that used to hold the center arches. The plan to leave them in place was based on an agreement with the Ministry of Cultural Heritage of Saxony (Dt.: Denkmalschutz) in order to keep the bridge listed in the Cultural Heritage Book (Denkmalschutzbuch), similar to what Americans have with the National Register of Historic Places. The old materials would (for the most part) be discarded, while some will be reused together with new materials made of sandstone and other rock-based materials to rebuild the structure to make it resemble its original form, when it was built in the 1700s. The project was announced in the Free Press in April and it is expected to be completed by November 2019.

During my most recent visit in Glauchau, I decided to have a look at the progress of the bridge and found some observations worth noting:

Film and commentary on this bridge:

This was filmed from the castle side with my newly-acquired Motorola moto 6 out of Pittsburgh. Incredible phone/camera and Glauchau was an incredible place for “target practice.” 😉

My observations of this project is best compared to a glass of wine that is half-full; half-empty. One can technically consider this project a total rehabilitation, where the bridge is stripped down to its arches, the original materials reused for the rebuilding process. This has been done on thousands of bridges of this kind throughout Germany, including the bridges in Erfurt, Dresden, Magdeburg, and Berlin, just to name some examples. It is similar to the coined-term “in-kind” restoration but with arch bridges, not truss structures.  However one could call this a total replacement because 90% of the original structure is completely gone; the materials used for the structure recycled and being replaced with similar materials that are used for other arch bridges. From an American modernist’s point of view, when a superstructure is replaced but the approach spans or even the original piers remain, it is a complete replacement, regardless of how you look at it.  Leaving the outer arches and the pylon stems in place kept the bridge from being completely destroyed and replaced, something that had been considered given its condition of being on the verge of collapsing, as you can see in Glauchau’s bridge tour guide.

So to sum up, this rehabilitation  project is one that is considered a wine glass that is half-full and half- empty. It is half-full because some of the important historic elements are being left in place, to be used as a foundation for the new materials that will come on top of it to retain its historic appeal. It is however half-empty because much of the original materials are not being used for the rebuild. Nonetheless, the bridge will retain its historic status in the books, yet my question I have, which will be answered through photos and commentary  during the course of this project, will be whether the bridge- the vegetarian main dish- will be the same as before? Or if it will be totally different, just like with the new multi-complex at the entrance to the Castle Complex- the main course dinner with lamb chops?

In simpler languages: will the architect be right about the changes not conforming to the castle surroundings, or will the people embrace the new form of history which features a cosmetic makeover but keeping its original historic form?

Stay tuned! 🙂

Spectacular Bridge Falls- The Top 10 and Film

207680-l

In connection with the collapse of the Morandi Bridge in Genoa, Italy, a couple of videos came to mind that I came across recently. Prior to the disaster, there has been a debate as to determining which bridge disasters should be in the top 10, for there are several sources that have their own set- be it in terms of history, natural disasters or even structural failures. Here are a couple examples of bridge disasters that feature the top 10 prior to the Genoa disaster. The first one focuses on disasters in terms of structural failure combined with history.

 

This video focuses on natural disasters and bridge failures, originating from Russia…..

Now here is the homework assignment for you: How would you rank your top 10 bridge disasters? What criteria would you set before finding your ten best examples? Would your focus be on the international stage or would you prefer local examples? And would you agree that your top 10 would be based on natural disasters, structural failures, both or neither of them?

Have a look at the videos and then look for your top ten bridge collapses. You may comment here or on the Chronicles’ facebook page.

Good luck! 🙂

Morandi Viaduct to be Replaced

ponte_morandi_crollato

1967 Cable-stayed Suspension Bridge to be replaced in response to the collapse. World-renowned architect to design new bridge.

bhc newsflyer new

GENOA, ITALY- Once one of the darlings of the city’s architectural landscape, Genoa is looking at seeing a new bridge being built soon. The Morandi Viaduct had spanned the valley with railways, streets and a small river going through the city, carrying the Autoroute 10 and E80 for 51 years until the tragedy of 14 August, 2018. There, one of the three towers of the concrete cable-stayed suepension bridge- which was a gap of 210 meters out of the total length of 1,180 meters- gave way during a severe storm, killing 43 people.

Two weeks after the collapse, plans are in the making to tear down the entire structure and replace it with a brand new one. According to information from multiple sources, the Five-Star Government will oversee the construction of a new bridge, to be built at the cost of the previous owner of the Morandi Bridge, the Autostrada Company, which had owned the cable-stayed suspension bridge for over a decade. The cost for rebuilding the bridge is unknown but it is estimated to be in the billions including the cost for removing the old structure.  The reason for the plan is, according to transportation minister Danilo Toninelli, the company owning the bridge had neglected the structure by ignoring the problems involving the concrete stayed cables and the roadway and by financing for the new bridge it would be the best possible way to compensate for the loss of people involved.

The bridge was built by Ricardo Morandi, who was known to have built several concrete cable-stayed suspension bridges during his days as a bridge engineer. One of them, the General Rafael Urdaneta Bridge in Venezuela that was built in 1964, is the longest bridge of his type in the world. The collapse of the bridge in Genoa. Like the bridge disasters in Minneapolis in 2007 and Seattle in 2015, the collapse of the Genoa Bridge is producing backlash as countries are scrutinizing his works carefully because of concerns involving the concrete cables that are supposed to hold the bridge in place, but failed in Genoa. Yet, like in the two previous disasters, despite all attempts to present the problems involving the bridge in the past decade, they were ignored until it was too late. The problems were ranged from a lack of maintenance to the lack of adaptation to the increase in the volume and weight of traffic in general.  The question is whether Italy will repeat the same mistake made by the US Government in trying to condem certain bridge types but failing due to the high numbers built and rehabbed combined with costs for replacing them. This is Italy’s third bridge failure this year, regardless of bridge type, and its 11th in five years.

The engineer behind the design and construction of Genoa’s replacement is a world-renowned architect Renzo Piano. For almost 50 years, the 81-year old Italian architect, who originates from Genoa, has built several masterpieces, including the Pompidou Centre in Paris, the Paul Klee Center in Berne, the Shard Tower in London and was the master planner of Potsdamer Platz in Berlin. He designed two bridges- one in Chicago and another in Amasuka, Japan. The Genoa Bridge project will be his fourth for his hometown and his third official for the bridge. How he bridge wil be designed and built remains in the air has the plans have been presented by the government. The Chronicles will keep you up to date on the latest stories there.
