Map with all coordinates: The Bjørvikatunnel ( Norwegian Bjørvikatunnelen ) is a six-lane road tunnel in the center of the Norwegian capital Oslo , which, together with the Festningstunnel , the Ekeberg tunnel and the Svartdaltunnel, forms the tunnel system of the Opera tunnel . The tunnel leads under the Bjørvika , a bay of the Oslofjord in the inner harbor of the city, and extends from the Bjørvika district of the same name to the old town of Oslo.
Location and scope
The tunnel connects the Festning tunnel at Havnelageret at one end with the Ekeberg tunnel and the Mossevei at Sørenga at the other end. It is 1100 meters long, 675 meters of which were built as an immersed tunnel with prefabricated sections (each 112 meters long, 27 meters wide and 10 meters high). Including all feeder roads and access ramps, the tunnel has a length of 8,000 meters. The tunnel ceiling is eight to eleven meters below the average water surface of the port.
Ventilation is provided in the east by four 40 meter high ventilation towers at Sørenga, one pair near the Østfoldbanen and the other near the sea. In the west, the tunnel is ventilated through the Festningstunnel, which has its own ventilation towers in Filipstad .
construction
Construction of the Bjørvikatunnel started on August 15, 2005. The tunnel leading to the east was opened on April 26, 2010 and the tunnel leading to the west was opened on September 20, 2010. The official opening by King Harald took place on September 17th, 2010. The tunnel is financed by the Norwegian state, the city of Oslo and toll revenues from the municipal operating company Fjellinjen . The construction costs for the project were estimated at 4.5 billion Norwegian kroner in 2004 , but amounted to 5.9 billion kroner in the end.
criticism
The constant expansion of an ever closer network of tunnels under Oslo has been criticized by road safety experts, who see an increase in the risk of fire as a result.
Awards
The tunnel was awarded the Norwegian architecture prize Betongtavlen in September 2011 .
