The Ryfylke Tunnel (Norwegian: Ryfylketunnelen) is an undersea road tunnel in Rogaland county, Norway. It is part of the Norwegian National Road 13 running between Stavanger and Ryfylke (district) under the Horgefjord (part of the Boknafjord). The tunnel is part of the Ryfast project. It is 14.4 kilometres (9 mi) long and is currently the world's longest subsea road tunnel, and the deepest tunnel of any kind. Both records are expected to be surpassed by Rogfast, which is projected to open in 2033.
The tunnel is designed for 10,000 vehicles per day and is built with one tube for each traffic-direction, and two vehicular lanes in each tube. The entrance on the Ryfylke side is located about one kilometre (one-half mile) north of Solbakk in Strand municipality (just south of Tau). The entrance on the "city side" is on Hundvåg island in Stavanger municipality. Construction began in 2013, and the tunnel opened on 30 December 2019. A half marathon was held in the tunnel on 5 October 2019.
