Stockholm County Council awarded China Railway Tunnel Group a contract for the construction of three working tunnels for the Blue Line to Nacka.
According to the council, the Chinese company meets all the requirements and provided the lowest bid.
For the metro extension to Nacka and Stockholm southern suburbs, the construction work will take around 6 years for the line to Barkarby and Arenastaden, and 7-8 years for the line to Nacka and the southern suburbs.
The Blue Metro line will be extended southwards from Kungsträdgården to Nacka and the southern suburbs. This entire section will be below ground. Sofia, Hammarby Kanal, Sickla and Järla are the metro stations to be built along the line towards central Nacka.
The branch towards the southern suburbs will run from Sofia to Gullmarsplan and on via the Slakthus area to Sockenplan. There it will connect with the existing Hagsätra branch, which will become part of the Blue line.
In 2014, an agreement was signed by the government, Stockholm County Council, the city of Stockholm and the municipalities of Nacka, Solna and Järfälla. The 2013 Stockholm Negotiation on Housing and Infrastructure means that the Metro would be extended to Nacka, Arenastaden in Solna and Barkarby in Järfälla, and that the Blue line would be extended and connected to the Hagsätra branch.
In total, the authorities will extend the metro system by 11.5 km.
