The Swedish Transport Administration has selected Skanska to construct the southern connection of Stockholm Bypass tunnel. The contract is worth about $153.8 million. The project covers about 350 meters of tunnel with two lanes in each direction, southbound connections and a new interchange.
Construction work will start in the spring of 2016, with expected completion in 2021. About 150 people will work in the project carried out as a turnkey contract. Construction of the overall project is expected to last about 10 years.
The Stockholm Bypass is a new route taking the E4 European highway past the Swedish capital. It will connect the southern and northern parts of Stockholm County, relieving arterial roads and the inner city of traffic. A new link west of Stockholm has been under investigation for several decades and many alternatives have been studied. To reduce the impact, just over 18km of the total 21km of the link are in tunnels.
