The Stockholm urban road tunnels

The lack of peripheral connections in the Stockholm region has created congestion and environmental problems in the radial road network. With respect to environmental constraints, tunnels present the only possible alternative for creating new accessibility for motor vehicle traffic. This is further enhanced by the favourable geological conditions for rock tunnelling in the region. Two major urban road tunnel systems, Norra and Sedra Lanken (the Northern and Southern Links), are in different stages of implementation. Construction works for Sodra Lanken have started while the time for the construction start-up for the Norra Lanken depends on further legal decisions.
