Highways England teams will be carrying out maintenance on trunk roads across the region over the next week.

Drivers should be ready for potential delays on main roads on the following routes:

A12 and A120, Essex: An ongoing programme of work to repair damaged safety barriers along the A12 and A120 in various locations continues this week, with working hours of 8pm to 6am, weeknights only. Single lane closures will be in place past the area being worked on.

A clearly signed diversion route will be in place via the A138, A130, A131, and A120 to Marks Tey and along the B1408, Cymbeline Way and the A134. Surface repairs will also take place within these closures.

A14 Cambridge to Huntingdon: Construction work on the new A14 Cambridge to Huntingdon scheme is underway. Highways England is currently carrying out a variety of tasks for which we need to close lanes or carriageways on the A1, A14 and some local roads at times, usually overnight between 8pm and 6am, unless otherwise stated. A clearly signed diversion route will always be in place for closures.
