The growing residential areas in the eastern suburbs of Ravensburg are to be attractively connected to the city center. A new bridge over Wangener Straße is planned to enable this link while respecting the surrounding natural environment.
The superstructure is designed as a three-span continuous beam. The supports consist of abutments at either end and a central Y-shaped pier. The superstructure is formed by a slender steel box girder with a haunched cross-section that increases in depth toward the pier node. This torsionally stiff steel box girder is well suited to absorb the eccentric loads resulting from the curved plan geometry.
The Y-shaped pier is constructed using high-strength precast concrete elements, allowing it to carry high compressive loads while ensuring durability and robustness. The bearings are designed as low-maintenance stainless-steel rocker plates, providing reliable performance with minimal upkeep.
The selected alignment and structural design of the bridge integrate sensitively into the ecologically valuable natural surroundings, which are of high importance for local biodiversity due to their structural richness. Construction within the forested hillside presents particular challenges. Special care is taken to minimize intervention in soil, topography, and vegetation to help protect the local fauna.
