The 130th Mystery Bridge takes us to the south of Germany to one of what Germans would call a “Soda-Brücke”. These are bridges that were built as part of the plan to construct a major road or highway only to have the project be abandoned with these structures considered in English to be “The Bridge to Nowhere.” The State of Bavaria has dozens of Soda Bridges that exist as they were part of Adolf Hitler’s grand project to build and expand the German Autobahn (Motorway) system to be used for the war efforts. Known as the Reichsautobahn, most of the total original length of 3900 kilometers are being used today, which include the three most traveled Motorways: the A4 Cologne-Dresden-Görlitz, A9 Berlin-Nuremberg-Munich and the A7 Flensburg-Hamburg-Ulm-Füssen (Bavaria). At almost 1000 kilometers, the A 7 remains to be the longest in Germany.
This Soda Bridge is located along what was supposed to be the Reichsautobahn nr. 87. This stretch of highway was constructed between 1938 and 1940, the same time as this bridge was built. This is located near Straubing in southeastern Bavaria and when it was built, it has a total span of 40 meters and a length of about 80 meters. Like most Autobahn-Bridges built during the Third Reich, the span was made of concrete, whereas the abutments and wingwalls were built using brick. Like with the rest of the stretch of Autobahn, it was never completed as the war halted the completion of the route and this bridge became expendable. As a result, you see the bridge like it is in this film clip:
This was found by chance, which makes researching more fun to do. 🙂
After the war, talks of finishing the motorway were in motion until the 1960s when the plan was abandoned for good. Why? Much of the stretch going towards the River Danube had an average grade of 5-6%, making it potentially dangerous for trucks to travel on the stretch. Henceforth, much of this stretch was either abandoned or converted into local highway use- this bridge was one that belonged to the former. The motorway was finished but relocated 6-8 kilometers away from the original route and was renamed Motorway 3, which is being used today, connecting Deggendorf with Cologne via Würzburg and Frankfurt. Another Motorway A 87 was in the planning but for the Stuttgart area. That plan was never realized.
Yet this still does not solve the mystery of how many other Soda Bridges that existed along the original Reichsautobahn 87, let alone how the route was followed exactly, and lastly, who was behind the design? This is where we open the page for discussion. Feel free to comment here or in the Chronicles’ facebook page or group page German History and Nostalgia.
