Neckar Viaduct, Weitingen, Steel bridge in Horb am Neckar, Germany
The Neckar Viaduct in Weitingen is a steel bridge crossing the valley as a major section of the A81 motorway. The structure features a box girder design supported by distinctive octagonal central towers and columns anchored on the surrounding slopes.
Construction of this bridge was completed in 1978 as a major advancement for regional infrastructure. The project was part of developing the A81 motorway, which created important transportation links between major cities.
The bridge structure represents German engineering precision through its octagonal central towers and framed double columns on supporting slopes.
The bridge is part of the continuous A81 motorway, enabling traffic flow between Stuttgart and Singen. Visitors can view the structure from the valley below or from the motorway itself, with both perspectives revealing the scale of the engineering.
The bridge uses special pre-stressed cables at both ends that distribute weight and stabilize the structure. These cables are designed in a particular way to ensure durability and safety across decades of use.
