Tunnels, service gallery and caverns

The two 2’900 m long tunnels and the two caverns with a cross-section of 130 m2 will be excavated by drill and blast method. In total, the tunnel builders will remove approx. 500,000 m3 of excavated material.

New tram connection

The new tunnel connects the towns of Fyllingsdalen and Kristianborg. One tube serves as a tram connection and the second tube, the safety tunnel, serves as a footpath and cycle path. The two caverns will be used as underground tram depots.

With its 2’900 m the tunnel will be the longest bike/pedestrian tunnel of Europe and the second longest of the world.
