The new Wertach bridge is a single-span structure made of reinforced concrete. The span is 18.5 m, the width - 5.30 m. Because the road runs in a curve, the bridge also had to have the curved shape. The crossing angle of the arch is 100 degrees. Due to the curves, the superstructure slab also had to have a transverse inclination of 2.5% on one side. In such complex geometric conditions, 3D modeling helped to create the formwork plans. A deep foundation with bored piles 88 cm in diameter is planned for the abutments. A drilling template made of unreinforced concrete is used to ensure that the bored piles are inserted precisely into the ground. The box-shaped abutments are made of reinforced concrete walls with a uniform thickness of 1.50m. The superstructure consists of a reinforced concrete slab with a constant construction height of 1.15m. The lateral tapering of the superstructure slab thickness to a dimension of 25 cm at the end of the cantilever arm is planned as a “fish belly” in order to be able to provide an ideal streamlined construction in the event of flooding. Concrete hinge joints transfer the loads from the superstructure to the substructure. The structure is planned with reinforced concrete caps on both sides, which have a width of 0.75 m to accommodate the railings.
