Ring Road

Norconsult has secured a €2.8 million contract to design a 10 km section of the city's ring road including three double-tube tunnels (1.6 km, 2.6 km, and 3.5 km), cross sections 2 x 55 sq metres, to be built in hard rock, probably using drill/blast. Work may start in 2004-2005. Norconsult is also responsible for the geological studies. Project cost around €250 million. Financing by the Norwegian public roads administration and toll. Visit www.norconsult.no 42/02.Three double-tube tunnels are planned on the west ring road in Bergen with connection to Flesland airport. From south to north, they are Birkelandsvatnet-Dolvik (1,640 m), which is partly a subsea tunnel, Dolvik-Sandeidet (2,600 m) with branch to existing road at Straume, and Sandeidet-Liavatnet (3,670 m). In Sandeidet, there is a second alternative with an underground connection. In that case, there will be one continuous tunnel from Dolvik to Liavatnet. Distance between tubes is about 10 m. Connections between the tubes every 250 m. Cross sections 2 x 53.5 sq m. Geology consisting of mostly of gneiss and amphibolite in the northern section, granite and gabbro in the south. Drill/blast method. In case of a continuous tunnel in Sandeidet, there may be a short cut-and-cover section. Support with rockbolts and shotcrete. Permanent lining of 4.5 m high concrete elements at the tunnel walls. Type of lining in the tunnel roof has not been decided yet. Project awaiting final approval of the plans and financing. Estimated work start in 2005. The project may be divided in several stages depending on financing. Geology studies by the University in Bergen. Experts from Statens Vegvesen - the Norwegian public roads administration - have investigated the risk for water leakages in the subsea sections. Risk analysis by Safetec Risk Management. Cost approx. NOK2.2 billion. Toll financing.
