The days of the tallest and longest bridge in Schleswig-Holstein are about to be numbered. The Rader Hochbrücke is a multiple span cantilever deck plate girder viaduct that spans the Baltic-North Sea Canal, carrying the Motorway 7 between Flensburg and Kiel. It’s also known as the Europabrücke because the motorway, which is the longest in Germany, connects Denmark (and subsequentially, Scandanavia) with Austria (and other parts of southern and eastern Europe) and also is one of the most heavily-travelled bridges in the state. The 1491-meter long bridge is so heavily travelled that cracks, rust and other ailments are showing on the almost half-century old viaduct, which has a main span of 271 meters and a height of nearly 60 meters. The viaduct has only four lanes of traffic, which makes it functionally obsolete due to high traffic congestion on the bridge. Smoke and other ailments from the ships passing underneath have added to the misery to the bridge.
Therefore, planning is underway to replace the entire viaduct with a brand new one. Beginning in 2022, crews will construct one half of the bridge which will be used temporarily for motorway traffic upon ist completion. Once traffic is diverted onto that span, the old viaduct will be demolished and in its place, the second half of the new bridge will be built. When the new bridge is completed by 2027, the structure will carry six lanes of traffic in total- three in each direction.
Unique about the new bridge, as you will see in the illustration below, is that the piers will be V-shaped and the cantilever design will be similar to that of the 1972 structure. In other words, the newer bridge will be fancier than the structure at present. It’s a win-win situation for the region of Rendsburg, which prides itself of its beloved High Bridge and Rail Loop, for two reasons:
There will be relief in terms of traffic in and around the city, reducing congestion and diverting unnecessary travel away from the city and
The city will be greeted with a unique bridge that will be appealing to tourists and bridgehunters alike. It will be not only modern but also unique.
And with that, a film on this project, courtesy of DEGES:
Even though the Motorway will remain open to traffic, construction will hinder traffic due to the machinery at the site. As a shortcut, you can take the Motorway 215 to Kiel, then follow Highway B76 to Schleswig via Eckernförde, crossing the Prince Heinrich Bridge that spans the Canal. Another alternative would feature taking the Motorway 23 along the North Sea coast from Hamburg. This changes to Highway B 5 after Heide. At Husum, follow Highway B 200 to Flensburg.
The Chronicles will keep you posted on the latest on this project.
And now, before we announce the winners of the 2020 Bridgehunter Awards, I have a few favorites that I hand-picked that deserve international recognition. 2020 was a year like no other. Apart from head-scratcher stories of bridges being torn down, we had an innummeral number of natural disasters that were impossible to follow, especially when it came to bridge casualties. We had some bonehead stories of people downing bridges with their weight that was 10 times as much as what the limit was and therefore they were given the Timmy for that (click on the link that will lead you to the picture and the reason behind it.) But despite this we also had a wide selection of success stories in connection with historic bridge preservation. This include two rare historic bridges that had long since disappeared but have now reappeared with bright futures ahead of them. It also include the in-kind reconstruction of historic bridges, yet most importantly, they also include historic bridges that were discovered and we had never heard of before- until last year.
And so with that in mind, I have some personal favorites that deserve international recognition- both in the US as well as international- awarded in six categories, beginning with the first one:
Best example of reused bridge:
The Castlewood Thacher Truss Bridge in South Dakota:
One of three hybrid Thacher through truss bridges left in the US, the bridge used to span the Big Sioux River near Castlewood until it disappeared from the radar after 1990. Many pontists, including myself, looked for it for three decades until my cousin, Jennifer Heath, found it at the Threshing Grounds in Twin Brooks. Apparently the product of the King Bridge Company, built in 1894, was relocated to this site in 1998 and restored for car use, in-kind. Still being used but we’re still scratching our heads as to how it managed to disappear from our radar for a very long time…..
Built in 1866, this bridge was unique for its arch design. It was destroyed by floods in 2015 but it took five years of painstaking efforts to put the bridge back together again, finding and matching each stone and reinforcing it with concrete to restore it like it was before the tragedy. Putting it back together again like a puzzle will definitely make for a puzzle game using this unique bridge as an example. Stay tuned.
While it has not been opened yet for the construction of the South Park Gardens is progressing, this four-span arch bridge connecting the Park with the Castle Complex was completely restored after 2.5 years of rebuilding the 17th Century structure which had been abandoned for four decades. Keeping the outer arches, the bridge was rebuilt using a skeletal structure that was later covered with concrete. The stones from the original bridge was used as a façade. When open to the public in the spring, one will see the bridge that looks like the original but has a function where people can cross it. And with the skeleton, it will be around for a very long time.
This one definitely deserves a whole box of tomatoes. Instead of rehabilitating the truss bridge and repurposing it for bike and public transportation use, designers unveiled a new bridge that tries to mimic the old span but is too futuristic. Watch the video and see for yourself. My take: Better to build a futuristic span, scrap the historic icon and get it over with.
Demolishing the Pilchowicki Bridge in Poland for a Motion Picture Film-
Paramount Pictures and Tom Cruz should both be ashamed of themselves. As part of a scene in the film, Mission Impossible, this historic bridge, spanning a lake, was supposed to be blown up, then rebuilt mimicking the original structure. The bridge had served a railroad and spans a lake. The plan was tabled after a huge international cry to save the structure. Nevertheless, the thwarted plan shows that America has long been famous for: Using historic places for their purpose then redo it without thinking about the historic value that was lost in the process.
A one of a kind Thacher pony truss, this bridge went from being a swing bridge crossing connecting East and West Lake Okoboji, to a Little Sioux River crossing that was eventually washed out by flooding in 2011, to the storage bin, and now, to its new home- Parks Marina on East Lake Okoboji. The owner had one big heart to salvage it. Plus it was in pristine condition when it was relocated to its now fourth home. A real winner.
Dömitz Railroad Bridge between Lower Saxony and Mecklenburg-Pommerania in Germany-
World War II had a lasting after-effect on Germany’s infrastructure as hundreds of thousands of historic bridges were destroyed, either through bombs or through Hitler’s policies of destroying every single crossing to slow the advancement of the Allied Troops. Yet the Dömitz Railroad Bridge, spanning the River Elbe, represents a rare example of a bridge that survived not only the effects of WWII, but also the East-West division that followed, as the Mecklenburg side was completely removed to keep people from fleeing to Lower Saxony. All that remains are the structures on the Lower Saxony side- preserved as a monument symbolizing the two wars and the division that was lasting for almost a half century before 1990.
Forest Fires along the West Coast- 2020 was the year of disasters in a literal sense of the word. Apart from the Covid-19 pandemic, which brought the world to a near standstill, 2020 was the year where records were smashed for natural disasters, including hurricanes and in particular- forest fires. While 20% of the US battled one hurricane after another, 70% of the western half of the country, ranging from the West Coast all the way to Montana, Colorado, Wyoming and the Dakotas dealt with record-setting forest fires, caused by drought, record-setting heatwaves and high winds. Hardest hit area was in California, Washington and even Oregon. Covered bridges and other historic structures took a massive hit, though some survived the blazes miraculously. And even some that did survive, presented some frightening photo scenes that symbolizes the dire need to act on climate change and global warming before our Earth becomes the next Genesis in Star Trek.
Demolition of the Historic Millbrook Bridge in Illinois-
Inaction has consequences. Indifference has even more painful consequences. Instead of fixing a crumbling pier that could have left the 123-year old, three-span through truss bridge in tact, Kendall County and the Village of Millbrook saw dollar signs in their eyes and went ahead with demolishing the entire structure for $476,000, coming out of- you guessed it- our taxpayer money. Cheapest way but at our expense anyway- duh!
Planned Demolition of the Bridges of Westchester County, New York-
While Kendall County succeeded in senselessly tearing down the last truss bridge in the county, Westchester County is planning on tearing down its remaining through truss bridges, even though the contract has not been let out just yet. The bridges have been abandoned for quite some time but they are all in great shape and would make for pedestrian and bike crossings if money was spent to rehabilitate and repurpose them. Refer to the examples of the Calhoun and Saginaw County historic bridges in Michigan, as well as those restored in Winneshiek, Fayette, Madison, Johnson, Jones and Linn Counties in Iowa. Calling Julie Bowers and Nels Raynor!
Collapse of Westphalia Bridge due to overweight truck-
To the truck driver who drove a load over the bridge whose weight was four times the weight limit, let alone bring down the 128-year old product of the Kansas City Bridge Company: It’s Timmy time! “One, …. two,….. three! DUH!!!!” The incident happened on August 17th 2020 and the beauty of this is, upon suggesting headache bars for protecting the bridge, county engineers claimed they were a liability. LAME excuse!
Located near the Göhren Viaduct in the vicinity of Burgstädt and Mittweida, this open-spandrel stone arch bridge used to span the Zwickau Mulde and was a key accessory to the fourth tallest viaduct in Saxony. Yet it was not valuable enough to be demolished and replaced during the year. The 124-year old bridge was in good shape and had another 30 years of use left. This one has gotten heads scratching.
Collapse of Bridge in Nova Scotia due to overweight truck-
It is unknown which is more embarrassing: Driving a truck across a 60+ year old truss bridge that is scheduled to be torn down or doing the same and being filmed at the same time. In any case, the driver got the biggest embarrassment in addition to getting the Timmy in French: “Un,…. deux,…… toi! DUH!!!” The incident happened on July 8th.
Consisting of vine bridges dating back hundreds of years, this area has become a celebrity since its discovery early last year. People in different fields of work from engineers to natural scientists are working to figure out how these vined bridges were created and how they have maintained themselves without having been altered by mankind. This region is one of the World’s Top Wonders that should be visited, regardless whether you are a pontist or a natural scientist.
This structure deserves special recognition not only because it turned 125 years old in 2020. The bridge is the longest of its kind on the South American continent and it took eight years to build. There’s an interesting story behind this bridge that is worth the read…..
For bridge tours on the international front, I would recommend the bridges of Schwerin. It features seven iron bridges, three unique modern bridges, a wooden truss span, a former swing span and a multiple span arch bridge that is as old as the castle itself, Schwerin’s centerpiece and also home of the state parliament. This was a big steal for the author as the day trip was worth it.
Geoff Hobbs brought the bridge to the attention of the pontist community in July 2020, only to find that the bridge belonged to a mansion that has a unique history. As a bonus, the structure is still standing as with the now derelict mansion.
The Bridges of Jefferson Proving Grounds in Indiana-
The Proving Grounds used to be a military base that covered sections of four counties in Indiana. The place is loaded with history, as not only many buildings have remained largely in tact but also the Grounds’ dozen bridges or so. Satolli Glassmeyer provided us with a tour of the area and you can find it in this film.
Now that the favorites have been announced and awarded, it is now the voter’s turn to select their winners, featured in nine categories of the 2020 Bridgehunter Awards. And for that, we will go right, this way…… =>
GLENCOE, MINNESOTA- When visiting McLeod County in 2011, rumors had it that the county had no more truss bridges. The last one had been taken down near Lester Prairie three years earlier. SInce my visit, two more truss bridge spans were discovered by local highway officials, including this one, the Koniska Bridge. The five-panel Pratt through truss bridge spans the South Branch Crow River and can be seen from the County Highway 11 bridge, a half mile away. Built in 1904 by William S. Hewett, one of the members of the Minneapolis School of Bridge Building, the bridge is 90 feet long, has A-frame portal bracings and is pin-connected. The bridge was once part of the village of Koniska, which had been abandoned before the bridge was replaced and left abandoned in the 1960s. Since then, it has sat quietly in the wilderness.
That is until now. Crews are planning to remove the bridge sometime in the fall or winter for safety reasons. The bridge’s decking is wooden but it’s rotting. The structure is rusting but there is no word on how bad. Bottom line is the avoidance of liability issues. It is unknown whether the bridge will be scrapped altogether or will be in storage for possible reuse. But as records indicate it was a Hewett truss, there is a chance to take the structure and relocate it for reuse. Furthermore, like another Hewett truss bridge in Mazeppa, it has the potential to be listed on the National Register.
If interested in the truss bridge, contact the McLeod County Highway Department in Glencoe. The contact details are here.
123-year old through truss bridge sent to the scrap yard.
Millbrook, Illinois- The bridge was the last of its kind in the county. It was a perfect fit as a hiking trail, a centerpiece for the village of Millbrook. Now the historic Millbrook Truss Bridge is no more.
Crews demolished the three-span through truss bridge on Monday, thus putting an end to all the talk of saving the structure. At the time of this post, crews are removing the truss parts and the stone piers that had held the structure in place for 123 years. The cost for the bridge removal is expected to be at $476,000 with the county and the forest preserve, where the bridge is located, expected to share the expense.
The Millbrook Bridge was built in 1897. One of the truss spans was replaced in 1910. It had served traffic until its closure to vehicles in 1984 and finally to pedestrians in 2015, following an inspection that deemed the bridge was unsafe for use. Talks of trying to save the bridge by handing over ownership and sharing the costs for rehabilitation failed to bear fruit due to liability concerns, something neither Kendall County, the forest preserve nor the Village of Millbrook were able to afford.
With the Millbrook Bridge gone, there are no more truss bridges in Kendall County and only a handful of historic bridges dating back to the 1920s remain in the county. Yet with the progress on its infrastructure with new roads and fewer railroads in operation, it is expected that the remaining historic bridges will be gone within a decade, thus making the county an HB-free state, one of an ongoing, increasing number of US counties that are following the trend. Sadly though, the new structures in place will be due for rehabilitation in 10-15 years, resulting in the question of whether this senseless progress of modernization was worth the price. It may be the case with the fall of the Millbrook Bridge in the short term. In the long term, one will be asking whether it was necessary.

Over 115-year old crossing over the Zwickau Mulde will be torn down beginning June 6. Replacement Bridge to be completed by End of November
LUNZENAU (SAXONY), GERMANY- One can see the bridge from the Göhren Railway Viaduct. The structure and the viaduct itself were once a photographer’s dream, especially because of its unique setting along the River Zwickau Mulde. Now the historic Waldcafé Bridge will become a memory.
The Waldcafé Bridge is a single span stone arch bridge with open spandrels resembling mini-arches. It was built in 1904 and has a total length of 60 meters and a width of 7 meters. The bridge carries State Highway 242. The bridge was recognized in the book Steinbrücken in Deutschland (Stone Bridges in Germany), which has a short summary on the historic structure. It was also listed as a technical monument by the Saxony Ministry for the Protection of Historic and Cultural Places (Denkmalschutz).
Workers are prepping for the removal of the historic bridge and replacing it with a more modern structure. After installing a temporary footbridge over the river, the bridge will fall victim to the diggers. The project to replace the span will last from now until the end of November, pending on the situation with the weather and the Corona Virus. The footbridge will provide direct access to the Waldcafé from the parking area on the southern end of the bridge, which will be a relief for business owners who had already taken a hit from the loss of customers because of Covid-19 but also the cyclists who otherwise would have been forced to detour via Lunzenau or Wechselberg. The cost for the whole project is estimated to be at approximately 220,000 Euros.
When work on the new bridge is finished, tourists and commuters will see a modern bridge that is wider and safer for use. Yet its historic flavor will be missed, Especially if one sees the new structure from the viaduct.
Located in the southern part of the district of Stendal, the city of Tangermünde is located on the River Elbe in the northern part of the German state of Saxony Anhalt. The city has over 10,400 inhabitants and is famous for its historic architecture dating back to the Medieval period. It’s one of only a handful of walled cities left in Germany that is in tact and one can find many historic places within the walls of the city, such as the towers, St. Stephan’s Church, Elbe Gate, and the historic city hall. The hanseatic city survived almost unscathed during World War II, for only a few trussed houses (Fachwerkhäuser) were destroyed.
Yet one of the city’s prized historic works, the Elbe River Crossing, was destroyed, leaving a scar on the city.
The Tangermünde Bridge was built in 1933, after taking two years of construction. The 833-meter long bridge features a steel through arch main span (at 115 meters) with a height of 15 meters and a vertical clearance of 9 meters. There were a total of 24 spans featuring many forms of steel girders, through and pony alike. The bridge remained in service for only 12 years. On 12 April, 1945, in an attempt to hinder the advancing American army, Nazi soldiers blew up the crossing while retreating towards Berlin. Nevertheless, to avoid being sent to Soviet camps, sections of the 9th and 12th Wehrmacht armies (Germany) surrendered to the Americans. They had used the destroyed spans to help residents fleeing the advancing Soviet army. A temporary crossing was constructed afterwards.
Here are some videos of the Tangermünde Crossing after it was destroyed by explosives. This was filmed after the Nazis surrendered to American troops. The gravity of the destruction of the bridge was huge and was a symbol of the destruction that would be bestowed upon in all of Germany.
The Tangermünde Crossing was rebuilt by the Soviets and the East Germans after Tangermünde became part of East Germany in 1950. They recycled the bridge parts and rebuilt a multiple-span crossing that featured as a main span a curved Pratt through truss with welded connections. Ist portal was I-beam with 45° angle heels. The remaining spans featured Bailey trusses, both pony as well as through truss. A tunnel view oft he Bailey through truss can be found in a blog which you can read here.
The structure lasted through the Fall of the Wall before it was replaced with the current structure, a steel through arch that mimicks that of the 1933 span. The bridge itself is almost twice as long as the original span, having a total length of nearly 1.5 km. It was built nearly two kilometers to the north of the old span, which remained in use until it was closed to all traffic in 2001 when the new bridge opened to traffic. The old structure was removed two years later. At the same time, the main highway, B-188, was rerouted, thus bypassing much of the city and having only local traffic going through town.
Today, the Tangermünde Crossing still serves local traffic. Its design has fit into the rest of the city’s historic landscape, much of which has been restored since 1990. Yet as we celebrate the end of World War II, many people remember how their prized work was destroyed towards the end of the war in a cowardly attempt to prevent the inevitable. And because the city was for the most part spared, Tangermünde has continued to become a tourist attraction. People can go back to the Medieval times and enjoy the architecture, before heading to the River Elbe to see the structural beauty. Despite being one of the youngest crossings along the Elbe, it is one with a story to tell to children and grandchildren alike.
189-year old arch viaduct from the British era imploded.
LONAVALA, INDIA- A piece of history from the British era in India has fallen. Crews of the Maharashtra State Road Development Corporation (MSRDC) brought down the Amrutanjan Bridge on April 7th, using explosives.It took no more than 10 seconds for the eight arches to come down in sequential order, as seen in the video above. Construction of the brick arch bridge started in 1829 and was completed less than a year later in November 1830. It is unknown who had directed the construction of the viaduct. The bridge was over 300 meters long and 20 meters high. The viaduct was integrated into the Mumbai-Pune Expressway in 2002, but was put out of service a decade later.
The Raigad District Collector provided the MSRDC the green light to proceed with the demolition, taking advantage of the Indian government’s Corona Virus lockdown order that is currently in place through May 3rd. It had been slated on the condemnation list since 2017 because of its deteriorating state. Nevertheless, there are still countless of ancient structures left belonging to the former British colony that had ruled India until its independence in 1948.
Communist-style old bridge to be torn down, road to be realigned to new span. Cable-stayed bridge to open to traffic by the end of May.
SCHLUNZIG/ GLAUCHAU/ ZWICKAU, GERMANY- Commuters driving between Glauchau and Zwickau will have one less route to take for the next quarter of the year. The Schlunzig Bridge, spanning the River Zwickau Mulde, along with the road connecting Schlunzig and the Volkswagen Company in Mosel will be closed down beginning Monday. The 1954 bridge will be torn down, while the road and the approaches will be realigned to the new cable-stayed bridge. The electrical and water mains will also be rerouted to the cable-stayed bridge prior to the old bridge’s removal. According to the Chemnitz Free Press, the demolition and road realignment project is expected to last through May.
Construction on the new bridge began in 2017 and it came in response to the inspection report on the (now) 66-year old bridge that revealed grave deficiencies that made rehabilitating the bridge impracticle. The bridge sustained severe damage in the 2013 floods resulting in the limitation of the speed limit to 30 km/h. Originally scheduled to open last spring, the construction on the cable-stayed bridge was slowed due to weather as well as the delay in the shipment of cables originating from Spain. The cables were spun and the stayed cables were completed in December.
The old bridge was built in response to the Great Flood of 1954, where 80% of the crossings along the Zwickau Mulde were destroyed. Its predecessor was one of them- a polygonal Warren through truss bridge with curved lattice strut and portal bracings, plus deck truss approach spans. It had originally carried a 6-gauge railroad connecting Mosel with Thum, located 3 km east of Schlunzig. The structure was a pre-fabricated concrete slab bridge whose piers had a semi-triangular shape, typical of Communist-era bridges built prior to 1989.
During the time of the bridge’s demolition and the preparation for the opening of the cable-stayed bridge, commuters will have the choice of using the Motorway 4 to Meerane and then Highway B93 to Zwickau or the B175 from Glauchau to Mosel via Niederschindmaas before joining the B93 at the Volkswagen Company exit.
Come time of the grand opening of the Schlunzig Cable-Stayed Bridge at the end of May, weather permitting, the Zwickau Mulde will have another suspension bridge added to the list of bridges of its type. The river in known to have over a dozen suspension and cantilever bridges- both past and present between Zwickau and Wurzen, including the Paradiesbrücke, the suspension bridge at Rochsburg, two suspension bridges at Rochlitz, the cantilever pedestrian span at Lunzenau and the suspension bridge in Grimma. With the new cable-stayed bridge at Schlunzig, it will attract more tourists, photographers and bridge enthusiasts to not only the village itself, but also to the region Glauchau-Zwickau as well as the along the river. A big plus for the region.
