Norway is studying the idea of building a mile-long tunnel to help ships navigate more safely through the exposed Stadhavet Sea on the western edge of Norway.
The Stad Ship Tunnel will be 1.7 km long, 37m high and 26.5m wide. The feasibility study has been funded and is under way. Construction could begin after 2018 and is expected to take about four years at a cost of about NOK 2.3 billion or $267 million.
Stad Ship Tunnel will be the world’s first full-scale ship tunnel of this size. It is part of the Norwegian national transportation plan that contains plans on large infrastructure investments to take place for the next 12 years (2018 – 2030) and is fully funded, according to Norwegian Coastal Administration, which is responsible for the project.
