Sammendrag
The Norwegian coastline is characterized by deep fjords cutting into the land mass, creating infrastructure barriers, and small, scattered population. The barriers traditionally have been overcome with ferry connections and in Norway there is an extensive network of ferries representing vital elements in the public service. However, such ferry connections are sensitive to harsh weather, expensive in operation and slow. The modern society has demands on quicker and more reliable services, particularly to allow new enterprises to grow at these remote places. In this context sub sea tunnels have played an important role in providing and establishing consistent fixed links between remote areas and the main land infrastructure network.
