Further underground work for Stockholm bypass 07 Dec 2017

Strabag has been awarded a further road tunnel contract on the Stockholm E4 highway bypass calling for drill+blast construction of twin 1.23km long tunnels.

Swedish Transport Authority Trafikverket awarded the €45 million contract to the Strabag Svierge AB division of the Austrian contractor for the tunnelling works on the Akalla section of the project. Contract award in late November will see a start of construction in January 2018 and towards a completion date by mid-2021.

The contract is in the same section of the 21km long, €3.1 billion project as an earlier contract secured by Strabag almost two years ago in early 2016. The works, including a 120m long cut-and-cover tunnel, have been undertaken by Zublin Scandinavia AB, a unit of the Strabag Ed Zublin AG subsidiary.

The 21km long bypass includes 18km of twin tunnel alignment for three lanes in each direction as well as a further 14km of entry and exit ramps and 4km of intermediate access tunnels, for a total excavated length of 54km. The Akalla section of the project is to be completed in 2021 and the entire project opened to traffic in 2025.
