A £100m tunnel could link Britain to the Orkney islands (Image: Getty) Everyone has heard of the Channel Tunnel , perhaps the UK's largest infrastructure project of the 20th century. But that's not the only major tunnel linking Britain's mainland underwater. There are now plans for a £100million undersea road tunnel between Orkney and Caithness, which would be about nine to 10 miles in length and solve transport link issues which have frustrated residents for many years.
Although the tunnel has not been discussed in great detail since around 2005, Scottish Office Minister Iain Stewart took a trip to the Faroe Islands in 2022 and the idea of a connecting tunnel resurfaced once again. The Faroe Islands’ use of tunnels has been extremely successful, particularly Eysturoyartunnilin, which not only connects the capital Torshavn with the second largest city but also acts as a tourist attraction due to it having the world’s first underwater roundabout. function loadOvpScript(){let el=document.
