Project information

Main carriageway between junction 22 and junction 24-6 November to December

We are resurfacing and repairing potholes and cracks in the concrete road surface on the A12 main carriageway between junction 22 and junction 24 in both the northbound and southbound directions. This project is part of the Highways England Concrete Roads Programme in the East region.

We have changed our initial approach so that we will work from Thursday to Tuesdays through to 2 December, rather than weekends through to 20 December. This is due to reduced traffic as a result of Covid 19 lockdown restrictions. We aim to complete the work earlier to avoid disruption in December when we expect lockdown to have finished, supporting people with Christmas shopping and other journeys, and to help fuel the economy. 

For safety and to minimise disruption to motorists, we need to close the road for the following periods to do our repairs:

A12 northbound closures:

  • 8pm Thursday 12 November until 6am Tuesday 17 November

A12 southbound closures:

  • 8pm Thursday 19 November until 6am Tuesday 24 November
  • 8pm Thursday 26 November until 6am Tuesday 1 December


Diversions: See map below

During A12 northbound road closures, traffic will exit the A12 at junction 19 onto the A130; then follow the A130; onto the A131; then follow the A131; then take the A120; follow the A120 to re-join the A12 at junction 25. 

During A12 southbound closures, traffic will follow the same diversion route roads.
