Stortinget vedtok prosjektet 23. mai 2017. At present the route is bridged by way of a lengthy ferry journey. More significantly, it confronts major obstacles along the route where it has to traverse many of the great fjords for which the country is famous. The road tunnel will be long. Both were well advanced this autumn and the excavations should be complete by the New Year. Credit: NCC. Learn more. Here is the tunnel project at a glance: 23th of May 2017 At this point the tunnel line passes and connects to a small group of islands, the Kvitsøy where there is a small community of around 500 people, which will be linked into the road with a 4km-long access connection. Four solutions are proposed, each stretching the technology. There is already a highway along the coast but it is not yet a major motorway for much of the length though some southern sections are being improved. The twin tunnels will have a diameter of 10.5m and a maximum depth of 392m below sea level. But there will be some tunnel wall insulation at the tunnel mouths, and water heating pipes installed in the final road surface in the tunnels, close to the portals. We use them to give you the best experience. It will open next year. The E39 Rogfast tunnel project is estimated to cost Nkr16.8bn ($1.9bn). The Rogfast tunnel will become the worldâs longest and deepest subsea road tunnel. The subsea fixed link will pass up to 390m below sea level in the Bokna Fjord and the twin tunnels will be linked with cross passages every 250m. The EUR1.73 billion project includes the longest (26.7 km) and deepest (392 m) underwater tunnel in the world. Ryfast has a space halfway along which widens slightly and features changed lighting. Small diagonal side tunnels would criss-cross between the two main tubes to stabilise them and to provide emergency escape routes. A tender was called off last year because the bids were much higher than anticipated. 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. Bjørn Fjord: Just north of Rogfast, is 5km across and 600m deep which begins to stretch engineering imagination. It subcontracted Powel for supplying the Gemini Terreng software for the project’s design. "We are expecting worldwide bidding as well as from Norway," said Brude "and there has been interest expressed from as far away as China." The contract letting is involved, he says, because of the engineering challenges of the project, and contractors' bids need to assessed on engineering competence and experience as well as price. THE ROGFAST PROJECT Tor Geir Espedal, Project Manager at the Norwegian Public Roads Administration, Western Region ABSTRACT Rogfast is the name of a 25-26 km long subsea tunnel being planned to pass under Boknafjord in Rogaland. Close. These are slightly smaller at 7m and 8m in diameter for intake and exhaust. Piers would be founded on the shore. The finished tunnel will feature video monitoring throughout combined with the latest radar detection systems to spot slowdowns and incidents in the tunnels. If you continue to use this site we will assume that you are happy with it. The E39 Rogfast project involves crossing the Boknafjord and Kvitsøyfjorden north of Stavanger with subsea tunnel. For a small country, with less than 5 million people, Norway has bold ambitions for its highways. This will be formed from precast concrete panels bolted to the rock walls. Both portals are in relatively unpopulated areas, the southern one at the small Harestad community, just north of Stavanger and the other at Arsvågen, a small community around the point where the existing ferry link makes landfall on the northern side. “Upon completion, it will become one of the worldâs longest and deepest subsea road tunnels.”, NCC Norway, Amberg Group, Volvo, Atkins, and Norconsult. So far, the first tender indicates a significant increase in cost in this huge mega project on the west-coast of Norway. Currently, this means drivers must use multi-kilometre ferry crossings at seven points along the whole route. 1. Upon completion, it will become one of the worldâs longest and deepest subsea road tunnels. Once the access tunnel and the two shafts are in place on the central contract there are further complications involving some 1.5km of connecting tunnels for the ramps and two roundabouts in the rock above the main tunnels. E39 Rogfast is the name given to the crossing of Boknafjorden and Kvitsøyfjorden north of Stavanger in the southwestern part of Norway with a sub-sea road-tunnel.
