Ryfast is an underwater tunnel system in Norway . It is part of the Norwegian National Road 13 and runs under the Horgefjord between the city of Stavanger and the municipality of Strand in Rogaland .

With a length of 14.3 km until the completion of the Rogfast project, the tunnel is the longest underwater road tunnel in the world - before the Tōkyō-wan-Aqua-Line , which runs under the Bay of Tokyo , Japan (9583 m), and the tunnel under the Yangtze (8950 m).

The project was approved by the Norwegian Parliament on June 12, 2012 and construction began in spring 2013. The cost of Ryfast is estimated at 5.22 billion kroner. The tunnel system replaces the ferry route between Stavanger and Tau and the ferry from Oanes to Lauvvik across the Høgsfjord .

The project consists of three underwater tunnels:

  • The Eiganes Tunnel is a 3700 meter long tunnel that runs below Stavanger - between the districts of Våland and Tasta. It consists of two tubes with a total of four lanes; construction began in February 2014.
  • The Hundvåg Tunnel is 5,500 meters long and runs under the Byfjord between Stavanger and Hundvåg (with a connection to the smaller island Buøy ).
  • The Ryfylke Tunnel (formerly known as the Solbakktunnel) is 14,300 meters long and runs from Hundvåg Island to Tau in Strand Municipality on the other side of the fjord. This reduces travel time between the districts of Nordjæren and Ryfylke in Rogaland .

The Ryfylketunnel, the longest underwater road tunnel in the world, opened on December 30, 2019 after almost seven years of construction. The two other tunnels of the Ryfast project, the Eiganes tunnel and the Hundvåg tunnel, should be opened in early February 2020. The opening was postponed, however, because the acceptance of the safety devices took longer than planned. But the scheduled date at the beginning of April could not be kept due to the COVID-19 pandemic . The opening took place online on April 22, 2020 without an audience on site, when Minister Knut Arild Hareide cut a tape in his office.
