Norconsult is the consultant for the design of tunnels, roads and construction. NPRA awarded a Nkr183m ($22.1m) contract to NCC Norway in December 2017 for the design and construction of a 2km-long cross-cut or side tunnel for the transportation of construction materials.Īmberg Group was contracted to carry out seismic investigations in the tunnel while Volvo provided the required construction equipment. Contractors involved in E39 Rogfast tunnel project Toll charges will be collected for 20 years, with the initial charge for light vehicles expected to be Nkr350 ($39) per passage. The state government is providing Nkr5.1bn ($569m) towards the project, which includes Nkr1.6bn ($178m) to be provided through the government’s scheme to lower the tolls. ![]() The E39 Rogfast tunnel project is estimated to cost Nkr16.8bn ($1.9bn). Up to 8.5 million cubic metres of rock will be excavated during the construction of the tunnel. The seismic prediction method is being used in the tunnel to obtain the rock mass quality. The first tunnel run was completed in January 2019 while the second passage was completed in June 2019, marking E39 Rogfast’s first breakthrough. After construction, it will function as a ventilation shaft. ![]() Construction detailsĪ 2km-long crosscut tunnel is built in two passages for transporting the excavation materials during the project’s construction. The tunnels will be operated from three locations and monitored from a road traffic control centre (VTS) equipped with full surveillance cameras. “Upon completion, it will become one of the world’s longest and deepest subsea road tunnels.”Ī 3.7km spiral-shaped tunnel will run 250m above the twin tunnels, up to Kvitsøy.Ī complex ventilation system with a pair of 10m-long ventilation shafts and four fans will be built under the Kvitsøy junction. The entry and exit ramps of the junction will lead to two roundabouts above the tunnel ceiling. The tunnel will feature a junction in the middle to provide road access to the island of Kvitsøy. It will have six longitudinal ventilation shafts, which comprise three that will be used for fresh air and three for polluted air. The tunnel will have two lanes on each side, with passages at every 250m to provide easy exits during emergencies. The twin tunnels will have a diameter of 10.5m and a maximum depth of 392m below sea level. E39 Rogfast tunnel detailsĮ39 Rogfast will be a twin-tube road tunnel, which will cross Boknafjorden and Kvitsøyfjorden north of Stavanger, replacing the current ferry over Boknafjorden. It will also improve business opportunities in the region by expanding the housing and labour segments. It will reduce the journey time between Stavanger and Bergen to approximately 40 minutes, including waiting time at the ferry terminal. The tunnel will have the capacity to carry up to 13,000 vehicles a year. Construction work started in January 2018 and is scheduled for completion in 2026. The Norwegian Parliament granted approval for the tunnel in May 2017. Upon completion, it will become one of the world’s longest and deepest subsea road tunnels.ĭeveloped by Norwegian Public Roads Administration (NPRA), E39 Rogfast tunnel is the first project under the ferry-free E39 highway concept along Norway’s West Coast. Credit: Volvo.Į39 Rogfast tunnel is a 27km-long subsea road tunnel currently under construction between Harestad, Randaberg and Laupland, Bokn in Rogaland County, Norway. The tunnel will have a maximum depth of 392m below sea level. The E39 Rogfast tunnel achieved its first breakthrough in June 2019. E39 Rogfast tunnel will be a 27km-long two-lane subsea road tunnel.
