The Wörth Danube Bridge is located near the city of Wörth an der Donau in the Upper Palatinate . The 404 m long bridge the BAB 3 spans between the connection points Rosenhof and Worth on the Danube with three fields in an angle of 85 Gon the Danube .
The plan of the motorway is straight along the bridge. The elevation shows a rounded dome with a longitudinal inclination of 2.1% and an outward transverse incline of 2.5%. The girder bridge was built with two separate superstructures for the one-way carriageways between 1977 and 1979.
Foundation and substructures
The abutments and pillars are built flat on gravel and gravel layers . The river piers have external dimensions of 26 m × 4.9 m and are inclined at 15 gons to the bridge axis.
superstructure
The prestressed concrete bridge has three fields with spans of 108.0 m - 168.0 m - 128.00 m and consists of two superstructures. These have a single-cell hollow cross-section with a width of 15 m, a construction height of 7.25 to 7.35 m (in the middle of the bridge) and a width of 6.0 m of floor slabs. The vertical webs are up to 1.2 m thick above the pillars, and the base plate is also reinforced there.
Construction work
The bridge was constructed using the incremental launching method with auxiliary supports with a maximum span of 62.5 m in section lengths of 17.5 m. The superstructure for the Regensburg carriageway was first concreted in the axis of the opposite lane in 25 cycles and then moved transversely into its final position. This was followed by the production of the superstructure for the Passau carriageway.
