Herrenknecht The big moment: breakthrough for Herrenknecht TBM ‘Chessie’ for the Parallel Thimble Shoal Tunnel, USA The Chesapeake Bay Bridge-Tunnel is a 37-kilometre-long structure of bridges and tunnels for motor traffic. Near the city of Norfolk and the adjacent naval base in the US state of Virginia, it connects the Hampton Roads region with the Delmarva Peninsula (part of Delaware, Maryland, Virginia). A previous bottleneck is now to be eliminated. At the end of January, a tunnel boring machine from Herrenknecht achieved a breakthrough for a tunnel that will contribute to this in the future.
