Rv. 13 – Ryfast
The Rv. 13 Ryfast project is the undersea tunnels which will connect the city of
Stavanger to the region of Ryfylke, when completed the tunnels will replace the
existing vehicle ferries which operate between Stavanger and Tau, and between
Lauvvik and Oanes. Currently the combined daily traffic volume for both ferry
routes is 4000 vehicles (AADT). Ryfast consists of two dual tube subsea tunnels,
The Hundvåg tunnel, from the new E39 Eiganes tunnel to the Island of Hundvåg,
and the Solbakk tunnel, which extends from the Hundvåg tunnel to Strand in
Ryfylke. Construction time will be 5.5 – 6 years with expected opening in 2019.
E 39 – Eiganes Tunnel
Today’s E39 bottlenecks in Stavanger, with traffic routed along heavily congested
local streets. The E39 Eiganes tunnel will be the new ”North / South” trunk route
through Stavanger, extending the existing motorway beyond the Stavanger central
business district, and significantly reducing local traffic above. The primary route
for the project is 5 km long, comprised of dual tunnels 3.7 km long, and 1.3 km of
ground level, two lane dual carriageway. In addition to the primary North and South
Bound tunnels, the project will also include tunnelled on and off ramps, and the
connection to the Ryfast Hundvåg tunnels. As a result of geometric constraints, and the existing topography a significant portion of the Eiganes tunnel will have
15-25 m of rock cover to the surface.
As the south western connection to the Ryfast project, theE39 Eiganes tunnel will
be constructed and managed jointly with the Ryfast project. Together the Ryfast
and Eiganes tunnel projects will produce 3.8 million m3 of rock, and finding a suitable
use for this material has been a challenge, the solution has been to utilise this
material for land reclamation at a number of sites adjacent to the project.
