The new Bleichinselbrücke across the Alt-Neckar is a four-lane integral road bridge with cycle and pedestrian paths. Due to its particular location in a flat meadow it was decided to design a composite construction with concrete deck and steel box girders acting as main girders. The concrete deck consists of precast slabs that are based on steel girders, and in-place concrete. It is thus possible to avoid temporary scaffolds and to minimise the impact on landscape and shipping traffic during the construction phases. The superstructure is based on inclined V-shaped abutments that are made from welded steel box girders. The abutments are monolithically connected with the superstructure. The foundation is carried out with pile caps and large-diameter piles.
