Highway Tunnel Extension Creates New District

In Stockholm, Sweden, the new Norra Länken (“Northern Link”) tunnel is a 13km highway connecting an important freight harbour and ferry terminals that will relieve congestion in the city centre by tunnelling the E20 and directing traffic underneath.

The Norra Station/Over Decking project involves extending the Norra Länken to create Hagastaden, a new district uniting the cities of Stockholm and Solna. In contrast to the rest of the Norra Länken, the new tunnel under Hagastaden constitutes a complex and multi-storey over decking connecting to the existing E4/E20 highway, which hereby “heals” the former no man’s land between the city of Stockholm and Solna.

Two Projects in One

Increasing the capacity through the Norra Station area (which will be known as ‘Hagastaden’) was a strategic objective for the Roads Authority. Including two new bridges and several broadening of existing bridges, the length of highway with boosted capacity is about 2km.

The Hagastaden district will provide 4,000 much-needed homes and offices for up to 10,000 people on a new deck above, stretching for almost 1km. The office blocks will have a strong emphasis on research facilities and ‘Life Science’, strategically located next to the Karolinska Hospital and the Nobel Institute.

Proud to Contribute to a Strategic Initiative

WSP is the sole consultant for the Norra Station project, working for both the Swedish Transport Administration and the City of Stockholm since 2008, planning the construction of the roads, masterplanning the new district, and carrying out a comprehensive environmental impact assessment for both.

We are producing tender documents for about 20 separate contracts, and have undertaken a great deal of consultation with a wide variety of stakeholders. We have been able to add significant value by being involved in both projects, avoiding duplication.
