German highway tunnel project

The project to build the Riederwaldtunnel highway tunnel in Germany is now likely to cost €477 million. The project was originally expected to cost €322 million. The tunnel will stretch 1.1km and will provide a connection between the A66 and A661 routes. Construction work on the tunnel, located near the city of Frankfurt, is expected to commence in 2020.

Construction work for a new tunnel stretch for the A44 route in Germany is now starting. The Boyneburg Tunnel section will measure 1.7km and forms part of the new A44 Autobahn, connecting the city of Kassel in central Germany with Herleshausen, where it links with the existing A4 route. The new tunnel section lies close to Wichsmannhausen while building the 70km stretch of the A44 is costing €1.7 billion.
