A12 junction 25 Marks Tey to junction 26 Stanway - concrete roads reconstruction
We're rebuilding the A12 between junction 25 at Marks Tey and junction 26 at Stanway. This will improve the safety, create a smoother quieter journey, and extend the life of the road to make it fit for the future.
We'll be reconstructing the A12 between Marks Tey and Stanway (between junctions 25 and 26) with work starting on 17 October 2022. 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, A11 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 innovative 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.
This video explains the process we go through to rebuild concrete roads:
There is more reconstruction, resurfacing and other maintenance work scheduled for 2023 on other stretches of this road. Read about how we're rebuilding and replacing some of the old concrete road surface on the A12
We started our work to reconstruct the road in Autumn 2022, and we expect to finish by late 2023/early 2024, subject to weather conditions.
We are using a ‘contraflow’ system to keep everyone safe and the road open whilst we’re working. A contraflow is when the road is shut in one direction and traffic is then moved over to drive on the other side of the road to share the remaining road space. This provides us with a clear working area, which means we can work more quickly and safely.
By using a contraflow, we’ll be able to keep two lanes of traffic in each direction whilst we do our work. Full road closures are only be needed when we set up and take down our roadworks.
We'll be doing the work in a few phases:
Phase one: will start at junction 25 northbound and head up to junction 26. Our construction workers will be in lanes one and two, with traffic in a contraflow.
Phase two: junction 25 northbound heading up to junction 26. Our construction workers will be in lanes two and three with traffic in a contraflow.
Phase three: junction 26 southbound heading to junction 25. Our construction workers will be in lanes one and two with traffic in a contraflow.
Phase four: junction 26 southbound heading to junction 25. Our construction workers will be in lanes two and three.
Due to the nature of the work, some noise and light disturbance is expected, but we’ll aim to keep this to a minimum. Thank you for your patience whilst we do this important road work.
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
We’ve set up a free SMS alerts service to warn road users, via text message, of any incidents that occur within our roadworks on the A12 during peak travel times.
You can sign up for this service by sending your mobile number to: ConcreteRoadsEssex@nationalhighways.co.uk. Please reference the ‘A12 Marks Tey to Stanway SMS service’ in the subject line of your email, so it's clear which scheme updates you'd like to register for.
Please note that you can opt out at any time by contacting us at the same email address.
