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 are 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 includes repairs to the concrete road surface, repainting white lining and replacing 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 started 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.
As our concrete road surface repairs to the southbound carriageway are progressing well, we will now be moving to the northbound carriageway to continue our repairs. This work will now be done in October 2021 instead of November 2021.
Read our latest newsletter for an update on our progress.
To do the repairs safely we will need to have overnight road closures on week nights.
The main carriageway is closed from 9pm. For the safety of the public and our workforce we will need to close the slip roads that join the A12 from 8pm before we close the main carriageway.
- Southbound from Monday 19 July 2021 until 15 October 2021: 9pm until 5am on Mondays to Thursdays and 9pm on Fridays until 6am on Saturdays.
- Northbound from 18 October 2021 until December 2021: 9pm until 5am on Mondays to Thursdays and 9.30pm on Fridays until 6am on Saturdays.
Note: We monitor the traffic flow and may close the A12 at 8pm to start our work earlier if there are low levels of traffic using the road. This will help us complete our road repairs more quickly.
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.
Noise Survey monitoring
We need to monitor noise levels for upcoming work on the A12 to ensure we are not creating any excessive noise levels during our construction work. The surveys are non-intrusive, and will take place week commencing 13 September. Monitors will be in place for at least 24 hours to collect the required data.
Survey work on the A12, junctions 25 to 26
Prior to work starting next year on reconstructing this stretch of the A12 carriageway, we need to carry out some survey work on road. For the safety of our workers and motorists we will be using lane closures.
Starting from 20 September 2021, there will be overnight lane closures from 8pm until 6am each Monday to Friday. We expect this survey work to have minimal impact on residents or motorists.
Please do follow the road signs and speed restrictions for your own safety and the safety of our workforce.
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.
