Tunnelling and coverage of the road network

Illustration: WSP

A prerequisite for the construction of Hagastaden is that parts of the road network are tunnelled and reinforced, so that the new city district can be built on top. Work on the E4/E20 motorway tunnels is complete, and in 2018 the Värtabanan railway tunnel was opened. The tunnel system covers some 14 hectares, about 28 football pitches. Above the tunnels, which extend 800 metres between Norrtull and just west of Solnavägen, housing, office buildings and parts of Norra Stationsparken will be built.
