Ryfast


Ryfast is a sub-sea tunnel system in Norway. The tunnel system is part of the Norwegian National Road 13 and it runs between the city of Stavanger, under a large fjord, and to the municipality of Strand in Rogaland county.
When the last section was drilled on 26 October 2017, Ryfast became the longest undersea road tunnel in the world, with its 14.3 km length greater than the Eysturoyartunnilin in the Faroe Islands Tokyo Bay Tunnel in Japan and the Shanghai Yangtze River Tunnel in China. It is also currently the world's deepest subsea tunnel, reaching a maximum depth of 292 meters.
The project was approved by the Norwegian Parliament on 12 June 2012 and construction began in the spring of 2013. The cost of Ryfast is estimated to . The tunnel system will replace today's ferry route between Stavanger and Tau as well as the ferry from Oanes to Lauvik across the Høgsfjorden.
The tunnel system consists of two subsea tunnels:
The Ryfast tunnel system joins another tunnel project under construction at the same time. The Eiganes Tunnel will run under the western part of the city of Stavanger.
The first phase of the tunnel system to open was the Ryfylke Tunnel, which officially opened to traffic at noon on December 30, 2019. The Hundvåg tunnel and the related Eiganes Tunnel are scheduled to open in February 2020, which will mark the completion of both construction projects.
