Project information


We'll be reconstructing the A12 between Marks Tey and Stanway (between junctions 25 and 26) later this summer. Reconstruction will involve completely removing the concrete road surface and some of the foundations, before rebuilding the road and resurfacing it with asphalt.

The East region has the highest concentration of concrete roads on our road network, including the A14, A12, A120 and M11.

Around half of the old-style concrete roads will either have repairs or will be replaced during the next five years.

We’ll be using new ways of working and new technology to provide a modern road that will last for decades to come. This will also make it easier and quicker for us to carry out repairs in the future.

Why we need the scheme

The surface of concrete roads that were designed between the 1950s and 1970s have an average life span of 50 years. Their surfaces are now reaching the stage where they will need to be repaired or replaced for safety reasons, and to help them be less noisy and better to drive on.

In late 2020, we made repairs to the A12 road surface between junction 22 and junction 24 in both directions. During early 2021, we resurfaced the A12 southbound main carriageway between junctions 27 to 26 and also repaired the road surface at the slip roads at junction 27. And in late 2021, we completed repairs to the A12 between junctions 15 and 19, and there is more resurfacing and other maintenance work scheduled for during 2022 on other stretches of this road.

When complete, the scheme will:

  • improve safety and provide a smoother rider for road users
  • reduce noise levels
  • create a new modern road with a 40 to 50-year lifespan that’ll be easier and quicker for us to repair in future
