Contractor 945 STRABAG will construct an additional section of road tunnel for Stockholm’s new bypass project. The contract is worth around €45 million and involves building two parallel bores with a total length of 2.5km for the Akalla tunnel section. The Stockholm bypass runs around the Swedish capital and is currently the largest road construction and tunnelling project in the country. The parallel tunnel bores will both be around 1.23km long and will be driven using conventional drilling and blasting techniques. Injection systems will be used to help stabilise the rock. The contract will also include installing the necessary facilities for electricity, water and waste water. Construction is to begin in January 2018 and is scheduled for completion in June 2021.

The Stockholm Bypass is being built in the north-western part of the city as the 21km, six-lane E4 highway ring. The entire €3.1 billion project is to be completed in 2025.
