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 these schemes
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. We're about to make 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.
Look below or Read our latest newsletter to find out more about our resurfacing work on the A12.
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.
We will be carrying out repairs to the existing north and south bound concrete road surface along the A12 from junction 15 Webb Farm Interchange to junction 19 Boreham Interchange. The work will include repairs to the concrete road surface, repainting of white lining and replacement of road studs (cat’s eyes.) Once complete, there will be a smoother and safer road surface.
Whilst the road is closed, alongside the road surface repairs we'll also take the opportunity to do routine maintenance jobs, such as tidying the verges, emptying the drains, road sweeping and checking and tightening the central reservation safety barriers.
Work will start on Monday 19 July 2021 and will be completed early 2022. To do the repairs, we will need overnight road closures on weekday nights, with a signed diversion route in place. Initially we will be closing the southbound carriageway, with work moving to northbound in November.
- Southbound from Monday 19 July 2021 until November 2021: Monday to Thursday from 9pm until 5am. Friday to Saturday from 9pm until 6am.
- Northbound from November 2021 until December 2021: Monday to Thursday from 9pm until 5am. Friday – Saturday from 9.30pm until 6am.
Depending on weather, additional road closures may be required.
Please use the diversion routes below.
Southbound Diversion Route
Drivers heading south should leave the A12 at junction 19 Boreham Interchange and join the A130.
Follow the A130 and then join the A1016.
Follow the A1016 and then join the A414.
Follow the A414 to re-join the A12 at junction 15. A signed diversion route will be in place.
Northbound Diversion Route
Drivers heading north should leave the A12 at junction 15 and join the A414.
Follow the A414 and then join the A1016 (Westway).
Follow the A1016 and then join the A130 to re-join the A12 at J19 Boreham Interchange. A signed diversion route will be in place.
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.
Starting in 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.
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 resurfaced and repaired 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.
