Kier Highways has reached major project milestones on M20 near Maidstone in Kent and the M23 in Surrey and Sussex with the opening of a new lane.

The firm, which is working on the behalf of Highways England, has opened a fourth lane in each direction to provide additional capacity for drivers.

To increase the road space an extra lane on the 10.5km stretch M20 between junction 3 at West Malling and junction 5 at Aylesford and 18km stretch M23 near Gatwick Airport, between junction 8 near Merstham and junction 10 at Copthorne has been added.

As Kier Highways will continue to install, test and commission new technology along the new lanes, a 50mph speed limit will be placed for both the roads over the coming weeks.

Both roads will also have CCTV monitoring and free recovery services.

Main works on both the projects began in 2018 and are expected to be completed on the M20 in spring and on the M23 in summer.

Kier Highways said that both the motorways required upgrade with additional lanes to reduce congestion, facilitate economic growth in the region and maximise motorway capacity while maintaining safety.

Kier Highways acting group managing director Joe Incutti said: “I am hugely proud of our teams on both the M20 and M23 smart motorway projects for achieving this key milestone.

“They have shown exemplary enthusiasm and commitment throughout the entire duration of these projects and have worked collaboratively with Highways England and supply chain partners to drive innovation, customer orientation, and above all safe delivery.

“This is an extraordinary achievement, and we look forward to completing both projects to provide much-needed motorway capacity in the coming months.”
