Werra Viaduct, Hedemünden, Railway and road bridge in Hedemünden, Germany.

The Werra Viaducts near Hedemünden are two parallel bridges, 33 metres apart, crossing the Werra valley at a maximum height of 59 metres. The older carries the A 7 motorway, the newer the Hanover–Würzburg high-speed rail line. Both are composite bridges with similar design, and the railway bridge links the Münden Tunnel to the Rauheberg Tunnel.

The first motorway bridge was begun in October 1935 and opened with the Göttingen–Kassel autobahn on 20 June 1937. Destroyed near the end of World War II, it was replaced by a temporary crossing until 1952. As the A 7 was widened to six lanes, the bridge was rebuilt between 1987 and 1993. The parallel railway bridge was built from 1986 to 1989 for the Hanover–Würzburg high-speed line.

The viaduct serves as a connection point between northern and southern Germany, integrating the Hanover-Würzburg railway line with the A7 motorway system.

The bridge experiences strong winds, particularly on the approach from Kassel, which is why speed restrictions are in place. Monitoring cameras on the northbound lanes help ensure safety and track traffic conditions.

The structure connects two tunnels on the high-speed rail line: the Münden Tunnel and the Rauheberg Tunnel, while crossing multiple transport routes below.
