It has been a few months since writing a review on a bridge book due to many commitments. But this first book review fits nicely with the topic on the Bridges of Lübeck in northern Germany, for it focuses on a landmark that should have been standing, but is no longer extant.
Located 6 kilometers north of the city in the suburb of Kucknitz, the Herrenbrücke has a history that is unique for the region and Europe. Located over the Trave and once hailed as the last bridge over this river before it empties into the Baltic Sea in Travemünde, only ten kilometers away, the Herrenbrücke was the only bridge in Germany that featured two single-leaf bascule bridges per roadway- four single leaf bascule spans all in all! Each span was 70 meters long. The height of the span over the Trave is over 50 meters tall. If one adds the approach spans, the total length of the bridge was over two kilometers. All in all, the Herrenbrücke was the largest bridge in Europe when it was bult in 1963 and opened to traffic at the beginning of 1964. Yet the 1964 span was the second crossing it this site. The very first crossing dates back to 1902 when a two-span swing deck truss bridge, using a Pratt design, was built. It was partially destroyed in a collision with the Swedish ship in 1909 and was rebuilt afterwards. In 1916, the bridge was electrified, allowing streetcars to cross the bridge providing a key connection between Siems and Kucknitz. The service was discontinued in 1958 and three years later, the suburbs and the City of Lübeck signed off on a contract to build the Herrenbrücke. Shortly after the new bridge was open to traffic, the steel truss swing bridge was removed.
But why did the bridge last for such a short time and had to be removed? Rainer Wiedemann, who lived near the bridge, documented the entire history of the bridge in his book, “Die Letzte Klappe: Abschied von der Herrenbrücke” (German for: The Last Word/Span: Farewell to the Herren-Bridge), which was published in 2011 and is available for ordering here. Mr. Wiedemann, who was born and raised in Lübeck and was a school teacher, documented the entire bridge prior to and during the removal process in 2005-06, which included detailed photos of the bridge, research into the bridge’s history (which included records of the bridge construction, old photos and postcards) and interviews with locals, city council members, and people who designed and built the Herren-Tunnel, the replacement of the Herrenbrücke which has been in service since 2005. Through this research, Wiedemann was able to look at the Herrenbrücke from all angles, including the reason why the Herrenbrücke had to be replaced after a short period in operation. The book is comparable with other books that were written about giant, popular crossings, such as the Sydney Harbor Bridge (75th anniversary book published in 2007), the Verrazano-Narrows and Brooklyn Bridges in New York City (former published in 2003, latter in 2013) and the Firth of Tay and Firth of Forth Bridges in the United Kingdom (published in 1991), where several aspects were combined into one- technical, sociological and historical- and formulated in a way where there is an equal balance of photos and text that is simple to understand, and even the reader who is a non-native speaker of German can follow the progress on the bridge’s history from start to finish.
This explains the reason behind the decision of the City of Lübeck and the suburbs to replace the Herrenbrücke with the Herrentunnel, which Wiedemann found substantial amounts of information on the bridge’s problems which dated back to shortly after the opening in 1964. In a nutshell, despite its popularity among its residents within a 20-km radius and beyond, the bridge was nothing but trouble for the city council. Technical problems resulted in a bascule span to not work resulting in a complicated detour. Traffic jams being 5-10 km long. But what doomed the bridge were the amount of cracks and corrosion on the bascule spans as a result of gas emitted from passing ships, weather extremities and salt used on the roadways. Despite undergoing rehabilitation on the bridge in 1981 to strengthen the concrete approaches and sandblast the bascule spans, it only delayed the inevitable, which was decided in 2001 in favor of a tunnel, financed solely by the private sector. Yet the process came at a price: many residents were displaced as their houses at the site of the tunnel were razed. Businesses were bought out, including the ship-builder Flender-Wirft, which was in business for over a century until it was bought by private investors in 2002. Almost immediately after the purchase, diggers and wrecking balls brought down the almost 400 square facility, reducing the warehouses and manufacturing buildings to a pile of rubble. This company was near the site where the 1902 swing bridge was located.
After the Herrentunnel was completed in July 2005, the Herrenbrücke was given its last hurrah on 26 August, 2005 the same time as the opening of the tunnel. Afterwards, it was demolished starting with the removal of the basule spans, then the approach viaduct spans and lastly the abutments and control tower- a process that took over two years to complete. There is almost nothing left of the bridge except for a pair of green cranes that have been placed there.
The author’s title is the subject for debate, depending on how the reader looks at the information. The Letzte Klappe could mean the last span, meaning the bridge stood the test of time, despite all the problems it had, and it stood to the very end, although its life was cut too short. Yet it could mean the last word, meaning the decision was final to get rid of the bridge, even if it was at the expense of more houses and businesses. But from the author’s standpoint, it could also mean the last word in terms of memories of the bridge and the area that is all but a ghost town. Siems and Kucknitz were affected by the bridge in a way that it became a key point that was replaced by the tunnel. But the tunnel came at the price of memories of the bridge and the businesses that once served the communities. As Wiedemann mentioned, Siems is almost non-existent, whereas Kucknitz has not fared better because of the tunnel. But progress can also bring its advantages, and perhaps the tunnel was for the best for commuters and tourists alike. Still to this day, people are trying to cope with the change, which will take getting used to.
And eventually people will adapt to the change, but the memories of the bridge and the region that once existed will remain, even through this book, which has become a must-buy for locals and pontists wanting to know about the Herrenbrücke, its rise and fall, and its legacy that will forever be part of Lübeck’s history as well as that of Schleswig-Holstein’s and Germany’s.
Grade: A+ (1,0)- for a well-detailed work on an iconic landmark that is comparable to other key bridges in Europe and the US. For engineers in Germany, a head-start for learning German!
