A12 concrete surface repairs and maintenance
We'll be carrying out repairs and maintenance on stretches of concrete surface on the A12. The work will include repair to the concrete road main carriageway, clearing drains, repainting road markings and new reflective studs (cat's eyes).
The East region has the highest concentration of concrete roads on our road network, including the A14, A12, A120 and A11.
Around half of the old-style concrete will either receive holding repairs or will be replaced during next 5 years.
We’ll be using innovative techniques and new technology to provide a modern road that will last for decades to come, and which is easier and quicker for us to repair in future.
Why we need this 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 are resurfacing the A12 southbound main carriageway between junctions 27 to 26 and also repairing the road surface at the slip roads at junction 27.

Our road repairs will help improve the safety of the road surface. It is essential that we complete repairs to the potholes and cracking to ensure a smoother and safer ride on the A12. Once complete, we expect the life of the road surface to be extended by up to 10 more years.
In 2022, we will be reconstructing the A12 carriageway between junction 13 Ingatestone and junction 15 Margaretting to replace the concrete road with a flexible asphalt lower-noise road surface.
As preparation for this work, from Monday 17 May 2021 we will be carrying out ground investigations and carriageway surveys and lighting maintenance for three weeks on the A12 between junction 13 and junction 15. To minimise the impact on local communities and motorists, the work will be done overnight between 9pm and 5am. We will only divert traffic from the A11 onto local roads where absolutely necessary.
To do the work, we’ll need to put the following closures in place:
- Full closure of the A12 northbound between junction 12 to junction 15 and a lane closure on the A12 southbound between junction 12 and junction 15 from Monday 17 May to Friday 21 May and from Sunday 23 May to Monday 24 May between 9pm and 5am each night.
- Full closure of the A12 southbound between junction 15 and junction 12 from Tuesday 25 May up to and including Thursday 27 May and from Tuesday 1 June up to and including Friday 4 June between 9pm and 5am each night.
Take a look at the diversion maps below.
A12 NB Diversion
To continue along the A12 northbound exit at junction 12 and take the diversion by following the B1002 through Mountessing, Heybridge, Ingatestone and Margaretting, before re-joining the A12 northbound at junction 15. We expect this diversion to add approximately 5 to 10 minutes to the usual journey.
A12 SB Diversion
To continue along the A12 southbound exit at junction 15 and take the diversion by following the B1002 through Margaretting, Ingatestone, Heybridge and Mountessing, before re-joining the A12 southbound at junction 12. We expect this diversion to add approximately 5 to 10 minutes to the usual journey.
Starting early summer 2021, we will be carrying out repairs and maintenance to the concrete road surface of the A12 from junction 15 (Webb Farm Interchange/Chelmsford bypass) to 19 (Boreham interchange) in both directions. The work will include repairs to the concrete road surface, clearing drains, repainting road markings and inserting new reflective road studs (cat’s eyes).
Towards the end of this year and during early 2022, we will be reconstructing the A12 carriageway between Marks Tey Interchange (junction 25) and Stanway (junction 26) to replace the concrete road with a flexible asphalt lower-noise road surface. Work includes renewing surface water drainage, replacing barriers and replacing old or damage signs.
As preparation for this work, from Monday 22 March we will be carrying out concrete and ground investigation surveys for three weeks on the A12 between junction 25 and junction 26. To minimise the impact on local communities and motorists, the survey work will be done overnight between 8pm and 6am. We will only divert traffic from the A12 onto local roads where absolutely necessary.
To do the work, we will need to close the road on the following dates:
- A12 northbound between junction 25 and junction 26 from Monday 22 March to Sunday 28 March between 8pm and 6am each night.
- A12 southbound between junction 26 and junction 25 from Monday 29 March to Wednesday 31 March, and Tuesday 6 April to Friday 9 April between 8pm and 6am each night.
From Wednesday 17 February 2021, we made repairs to the concrete surface on the A12 at junction 27 Spring Lane.
The work took around four weeks, and we also cleared drains, repainted road markings, and inserted new reflective road studs (cat’s eyes). At the same time, we resurfaced the A12 southbound carriageway between junction 27 and 26. You can read about this project in our March A12 newsletter.
During November and December 2020, we have been 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. You can read about the work we did in our two newsletters:
We changed our initial approach to take advantage of the reduced traffic as a result of Covid 19 lockdown restrictions. We were able to complete the work earlier to avoid disruption in December, supporting people with Christmas shopping and other journeys, and to help fuel the economy.
