The Sandoy tunnel will be the fourth subsea tunnel in the Faroe Islands and will connect the island of Sandoy to the greater part of Faroese infrastructure. The tunnel will be 10.6 kilometres long. The lowest point is 147 metres below the water surface and just like the Eysturoy tunnel, the steepest inclination will be 5 percent. According to schedule, the work of constructing the Sandoy tunnel will begin in 2018. The work is expected to take 5 years, which means that the Sandoy tunnel is expected to be finished in 2023.
