Köhlbrand Bridge

The Köhlbrand Bridge is a cable-stayed bridge in Hamburg, which connects the harbor area on the island of Wilhelmsburg between the Norderelbe and Süderelbe branches of the Elbe river with motorway 7. The bridge was opened on 9 September 1974 and spans the 325 m wide Köhlbrand. The cable-stayed bridge was designed by civil engineer Paul Boué and architect Egon Jux. According to a report in April 2018, the bridge could, according to alternative plans, be replaced by a double-storey tunnel, which on the lower level provides a lane for autonomously moving container transporters. Although a tunnel would be more expensive in construction than a new bridge, the maintenance costs would be much lower in the long term.
