They will be the longest railway tunnels in Scandinavia, part of the Follo Line project, the biggest transport infrastructure ever built in Norway.
Twin tunnels, each 19.5 km long with an internal diameter of 8.8 meters, will connect the cities of Oslo and Ski, establishing the central axis of the intercity development to the south of the Norwegian capital.
Delvalle, after identifying the necessities of the engineering, developed painted stainless steel enclosures that were special designed for tunnels. This enclosure can provide the tightness against water and a high corrosion resistance.
