location

The Sinzing Danube Bridge is a 930 m long bridge on the Federal Motorway 3 near Regensburg .

The structure spans the Danube with nine fields between the Sinzing junction and the Regensburg motorway junction , the Regensburg – Ingolstadt railway line on the left bank of the Danube and two municipal roads, as well as the historic Max-Schultze-Steig nature reserve on the right bank of the Danube . The plan of the motorway is straight along the bridge.

The bridge is designed as a girder bridge with two separate superstructures for the directional lanes. The first work on a motorway in the Regensburg area took place at the end of the 1930s. At that time, among other things, the construction of the substructure of a Danube bridge began. The bridge was finally erected between 1961 and 1966, at a construction cost of DM 27 million. The planning, construction and assembly were in the hands of the MAN plant in Gustavsburg . The Sinzing bridge was the first bridge of its kind whose structural analysis was calculated entirely electronically.

Foundation and substructures

The western abutment has a deep foundation over bored piles, the piers and the eastern abutment are flat on limestone rock . The massive, approximately 40 m high pillars have a massive rectangular cross-section made of unreinforced concrete and a granite wall. The support banks are made of reinforced concrete.

superstructure

The bridge has two separate steel superstructures with the continuous beam as a structural system. The total span of the nine-span bridge is 930.1 m, with spans of 3 × 90.0 m - 95.0 m - 100.0 m - 105.0 m - 115.2 m - 129.9 m - 115.0 m . The construction height is variable and with 3.5 m to 5.1 m adapted to the span. In the transverse direction, each superstructure is designed as a welded plate beam construction with two full-walled main girders and an orthotropic deck . The main girders are arranged at a distance of 7.5 m, and are connected to each other at a distance of 8.75 m by means of frameworks. The deck is 14.25 m wide.
