M4 junction 4b to M25 link road full weekend closure - Friday 13 to Monday 16 September 2024
We need to close the link road connecting the M4 eastbound to the M25 southbound (anticlockwise towards the M3, M23 and M20) from Friday 13 September 11pm to Monday 16 September 5.30am.
For safety reasons, we will also close the eastbound entry slip road at the M4 junction 5 Langley Interchange over the same weekend.
The link road which connects the M4 eastbound to the M25 northbound (clockwise towards the M40, M1 and M11), will remain open over the weekend.
Our work has been scheduled over a weekend to avoid peak midweek traffic demand.
However, we’re expecting the M4 between junctions 5, 4b, and 4 to be busier than usual at times over the weekend.
Please plan ahead and allow more time for travel.

Project information
The expansion joint runs across the width of the bridge and weighs approximately 4.5 tonnes. It is reaching the end of its serviceable life. We need to replace the bearing in a single, extended shift before the bridge can be safely reopened.
We've co-ordinated this closure with the major upgrades already underway on the M25.
Replacing the expansion joint will make the bridge structure safe and extend its lifespan.
Our work will also reduce the need for disruptive emergency repairs in the future.
