The Norwegian Public Road Authority recently awarded two contracts, together worth $900 million, for the world's longest subsea road tunnel. The 16.5-mile long Rogfast tunnel, under Boknafjord north of Stavanger, would form the southern end of the planned 690-mile E39 coastal highway.
A joint venture led by Switzerland-based Implenia A.G. with Norway's Stangeland Maskin A.S. started the New Year announcing its $400-million contract for the fjord's southern 5.3 miles of twin rock tunnels, due for completion in 2030. Implenia’s global tunneling chief, Erwin Scherer, described the contract as "large and complex."
