E6 Nordnes Tunnel - Bergli portal
Norway
The Nordnes Tunnel reduces the risk of traffic disruption due to avalanches and landslides and it also lops some 8 km off this part of the E6 trunk road. A tunnel formwork carriage made up from standard materials was used on the portal, and after only minor modifications it was then also used for the trumpet-shaped broadening zone.
