The Sakhalin Tunnel (Russian: Сахалинский тоннель) is an incomplete and currently postponed construction project, which after completion would connect the island of Sakhalin with mainland Russia via a tunnel of approximately 10 kilometers (6.2 mi) under the Nevelskoy Strait (the narrowest part of the Strait of Tartary). On January 16, 2009, it was suggested by the Russian government the link could be completed with a bridge, rather than tunnel.
