The Ryfylket tunnel will be completed in 2019 and will provide connection between small communities and the large city municipality of Stavanger, Norway. A large population travel daily by ferry, and will in the future travel through this 50 km long tunnel project.
The Ryfylke tunnel is a 14.3 kilometer long subsea tunnel between Solbakk in Strand and Hundvåg in Stavanger. When the tunnel is finished, it will be the longest subsea road tunnel in the world. Part of the tunnel has a incline of 7 %. At the deepest, the tunnel is 292 meters below sea level. There are two main engineering contractors and one main contractor for the electric technical work.
The tunnel consists of two tubes, one for each direction, four lanes in total. For safety reasons, lay-bys and cross-connections is installed every 250 meters, and the tunnel can handle closures and divert traffic into the second tube. A feature that require more signs and security systems, and give us one of the most complex road tunnels in the world.
In October 2019, before opening for traffic, a half marathon race will be arranged. 5000 competitors will participate in this special underground hill-climb race.
