Norway is to build the world's first full-scale ship tunnel in the Stadhavet Sea, a hazardous region of coastline that Is difficult to navigate. At an estimated cost of £245m, the 1,700m-long Stad Ship Tunnel will take approximately three-to-four years to build and will require the removal of three million cubic metres of rock. The project will be delivered by the Norwegian Coastal Administration (NCA) with construction expected to begin in 2019. Once complete, the tunnel will have a ground-to-ceiling height of 49m, a cross-sectional area of 1,625m~2 and have a width of 36m between tunnel walls.
