Lechtal Bridge Schongau

The Lechtalbrücke Schongau is a road bridge in the municipality of Schongau, about 2.5 km south of the Schongau city centre. The structure spans the Lech reservoir of Lech barrage level 6 with two lanes and a 2.5 m wide footpath and cycle path on the northern side of the bridge and a footpath on the southern side. The federal highway 17 and the federal highway 472 run over the bridge.
The bridge was built as part of a bypass of Schongau and Peiting in the years 1988 to 1991 in order to relieve the local thoroughfares with over 30,000 vehicles a day. As the most important structure on this line, it has a rising gradient of no more than 3.4 % in the longitudinal direction from west to east and is designed in the elevation in the shape of a trough with a radius of 20 km. In the ground plan, the road route runs straight in the construction area. At the western abutment, the structure, which is up to 45 m high, first spans the valley floor over a length of about 150 m and then the Lech reservoir, which is up to 14 m deep. The eastern abutment lies behind a high steep slope with an inclination of up to 50°. The construction costs amounted to around 21 million DM, the construction period was three years.
