Sandoyartunnilin is a planned undersea road tunnel in the Faroe Islands. It will connect the main island of Streymoy with Sandoy to the south. The length of the tunnel will be 10.7 kilometres. The estimated cost is 860 million DKK. Construction will begin in 2018. The tunnel is expected to be ready for traffic in 2021, after which the ferry Teistin will cease its route between Gamlarætt and Traðardalur (between Skopun and Sandur), near the Inni í Dal stadium.
