COWI part of joint venture developing preliminary design on behalf of Highways England

The government has announced a tunnel under the Thames east of Gravesend and Tilbury as the preferred route for the new Lower Thames Crossing.

The Lower Thames Crossing Joint Venture – comprising COWI, CH2M and Arcadis – is acting as Technical Partner to develop the preliminary design for the project, working on behalf of Highways England.

Executive Director Tunnels Andy Sloan commented: "I am delighted the government has announced the preferred route. This will enable the project to move forward to the next phase of development. We are proud to be working for Highways England on one of the biggest infrastructure projects in the UK."

The crossing will create a new link between the A2 and the M25 and reduce the burden on the busy Dartford Crossing. The planned route will run from the M25 near North Ockendon, cross the A13 at Orsett before crossing under the Thames east of Tilbury and Gravesend. A new link road will then take traffic to the A2 near Shorne, close to where the route becomes the M2.

This route was identified by the majority of nearly 47,000 respondents to a consultation on a new Lower Thames Crossing as the best solution for reducing traffic and congestion at the Dartford Crossing and for boosting the economy by improving links to London and the Channel ports.
