Railway Bridge across the Aller river near Verden

Verden, Germany, 2015

In the course of the DB-railroad line Wunstorf-Bremerhaven, an innovative new bridge replaces the existing bridge across the Aller, integrating itself harmoniously into the surrounding country side. The continuous, slender trough bridge convinces through its appropriate material application and moment-diagram formed webs. These connect on both sides with the orthotropic steel deck. The stiffeners of the web in the region of the main span across the Aller are arranged in a fan-shape, following the flow of forces. To harmonize the alignment of the approach ramp, the height of the outer steel girders remains constant and the web stiffeners arranged to be purely vertical. The bridge superstructure is supported by bearings on the slender pier walls and abutments, where the fixed point in the longitudinal axis is located on the northern pier. The bridge is built in eight sections in incremental launching method.
