Sauer Valley Bridge

About

The Sauer Valley Bridge is a motorway (Autobahn) bridge high above the Sauer River which at this point marks the frontier between Luxembourg and Germany. It was constructed between 1984 and 1987. The bridge is 1,195 m (3, 920.6 ft) long and, at the lowest point of the valley, 98 m (321.5 ft) above the valley floor. Viewed from above it is formed as a curve with a radius of 2,000 m (6, 561.7 ft). Additionally, the road surface has a constant 1% gradient. The girder bridge was built with a single superstructure for both carriage ways, and is positioned approximately a kilometer to the north of Wasserbillig in Luxembourg.
