The contract is part of the extension of the Blue Line and includes the construction of two line tunnels and a service tunnel with a total length of 3,100 m, as well as a new 300 m long subway station at a depth of almost 70 metres below the existing Gullmarsplan transport interchange.
Works also include the construction of a high-speed elevator shaft connecting the existing transport interchange with the new station, ensuring passenger transit between it and the existing metro stops of the Green Line, Tram Line and bus station. The project is scheduled for completion in 2025.
Opened in 1950, Gullmarsplan is Sweden’s third largest station and a major connection point for buses and the metro. It connects the city centre and the southern part of Stockholm, with a daily traffic flow of over 84,000 people.
