RV 13 Ryfast / E02 Solbakk tunnel

The Solbakk Tunnel located in Stavanger, Norway, stretching 14 km, is currently one of the longest under­water road tunnels. The con­struc­tion was an in­tegral part of the Ryfast project, a com­pre­hensive ex­pansion program of the E39 coastal road. The two direct­ionally separated two-lane tubes under the seabed were installed at a maximum depth of 290 m below sea level. This makes this structure the deepest under­water road tunnel in the world today.
