Bridge view of the Sulzbachtal bridge near Denkendorf

The Sulzbachtalbrücke is located in the district of Denkendorf in Baden-Württemberg . The bridge carries the traffic of the federal motorway 8 between the junction of Wendlingen and Esslingen over a valley basin with the Sulzbach that gives it its name .

The prestressed concrete structure consists of a three-lane girder bridge with seven openings for each lane. It is 365.4 meters long and a maximum of 42 meters high. The spans are between 40.6 meters in the two end fields and 63.8 meters in the middle field.

history

The first motorway bridge was built between 1934 and 1936. Karl Schaechterle and Fritz Leonhardt, with architectural advice from Paul Bonatz, designed the roughly 20-meter-wide structure as a steel girder bridge supported by slender steel frames. The frames had a strong crossbar at the top and were hinged at the top and bottom. On April 18, 1945, the Wehrmacht blew up the building. The remnants of the old steel bridge were the construction of the Main Bridge Wertheim reused

In the years 1952 to 1954, the girder bridge was rebuilt in the same geometry as a steel composite construction with a pre-stressed deck according to plans by Hellmut Homberg . An ankle joint of a support frame is set up on site.

From 1978 to 1980, as part of the six-lane expansion of the motorway, a parallel prestressed concrete structure was first built for the Ulm roadway. Then the old bridge from 1954 was blown up and the second prestressed concrete bridge for the other carriageway, which was completed in 1984, was built on the old foundations at the same point. The box girder bridges were built using the incremental launching method .
