Work begins later this month
We plan to start work on Monday 29 July. It will take us up to four months to complete.
To minimise disruption, this work will take place weeknights, when there is less traffic, with closures between 8pm and 6am, unless stated.
During the day, the motorway will be open as usual.
Closure information: Monday 29 July to Tuesday 6 August
There will be overnight lane closures on the M4 between junctions 17 and 18 between 8pm and 6am, at least one lane will remain open in each direction.
We’ll then work our way along the carriageway and slips roads using full and lane closures.
Our first full closure will be the westbound carriageway between junction 17 and 18 on Tuesday 6 August, 9pm to 6am. A diversion will be in place via the A350, A420 and A46.
Check back for details of upcoming closures as our work progresses.
