Norway's long tunnel

摘要

Norway looks set to retain its position as a leader in tunnelling with the project moving forward to build a new link connecting the city of Stavanger with Bokn. This 27km road tunnel is being designed to carry four lanes of traffic, which would make it the world's longest underwater road tunnel. It will also be the world's longest four lane tunnel as well as the world's deepest road tunnel, dropping around 385-390m below sea level. The Rogaland Fixed Link will form part of the E39 route, connecting Kristiansand, Stavanger, Haugesund and Bergen in the south of Norway.
