A120 eastbound and westbound between Stansted Junction and Dunmow West Interchange – maintenance work
Dear Customer
I’m writing to let you know that we plan to carry out maintenance work on the A120 in both directions between Stansted junction and Dunmow West Interchange.
This work includes resurfacing the road, refreshing road markings, replacing worn road studs, also known as cat’s eyes, and upgrading roadside technology.
Once complete, drivers will benefit from a safer, smoother and more clearly marked road. The upgraded technology will also help us monitor our network, manage traffic flows and keep drivers informed so they can travel safely.
We plan to complete this work over two weeks from Monday 8 June 2026. We’ll work overnight between 9pm and 5am on weeknights only, weather permitting.
Closures and diversions
To carry out the work safely, we will need to close the A120 in both directions between Stansted Junction and Takeley and divert traffic as detailed in the table below.
