As part of the expansion of the ICE high-speed link between Munich and Nuremberg a new railway-track became necessary, running directly next to the existing twin-track railway bridge. In three sweeping waves the bridge responds eloquently with its simple but novel structure to the beautiful truss girder bridge dating from 1869. Slender steel sails form the webs of the multi-span trough bridge with its two main spans of 55 meters, their shape corresponding to the bending moment diagram of a continuous girder. The lower chord, an inverted T-beam, is compressed like the deck of a self-anchored suspension bridge and likewise made of the appropriate material concrete. Beyond the Danube, the bridge spans streets and shoreline paths and, supported by pendulum columns, gradually phases out.
