Our highly experienced teams are working collaboratively and in joint venture to support delivery of HS2. The new high speed railway will improve connections across the UK, add increased capacity and help the UK to reach net-zero carbon emissions by 2050.

Skanska, as part of the Skanska Costain STRABAG joint venture, is delivering full detailed design and construction of Phase One of the UK's new high-speed railway in the southern section of the overall High Speed Two (HS2) project.

The southern, London tunnels section, comprises construction of 26 miles of tunnels between Euston and West Ruislip, as well as numerous viaducts, bridges and embankments.

We’re using six giant tunnel boring machines (TBMs) to excavate the 21km route, while a seventh TBM will excavate a logistics tunnel, to be used to bring construction materials into the tunnels and remove muck. The twin-bore tunnels we’re constructing are 13 miles long and up to 50 metres deep.

Our teams are working on 23 main sites at Euston, Old Oak Common and West Ruislip – employing around 5,000 people, including supply chain. This includes people from local communities, 600 of whom who were previously unemployed. We have also trained some 160 apprentices and helped those who were previously homeless, long-term unemployed or vulnerable for other reasons.

Building for a sustainable future

It’s not just what we build, but how. We’re finding ways to cut carbon and costs through trialling and implementing new techniques.
