The Langfjord Tunnel is a proposed subsea road tunnel which would cross Langfjorden between Molde and Rauma in Norway. It may also be built with a branch to the island of Sekken. As part of County Road 64, the tunnel would replace the Åfarnes–Sølsnes Ferry, and allow Romsdal ferry-free access to Eastern Norway, as well as connect Molde and Rauma. If the branch is built, it would replace the Molde–Sekken Ferry, giving the island a fixed link. The main tunnel would be between 10 and 11 kilometers (6.2 and 6.8 mi) long, which the branch would be slightly shorter than 5 kilometers (3.1 mi) long. The tunnel would reach 330 meters (1,080 ft) below mean sea level, making it the deepest subsea tunnel in the world.
