It will involve the overnight closures, in various phases, of the eastbound M4 between junctions 4 and 3, the westbound carriageway between the exit and entry slip roads at junction 4b, the westbound entry slip road at junction 4 and the westbound exit slip road at junction 5.

The work will be carried out overnight between the following times:

  • Monday to Thursday 10pm to 5.30am
  • Friday 11pm to 6am
  • Saturday 10pm to 6am
  • Sunday 10.30pm to 5.30am

Clearly signed diversion routes will be in place during the closures.

Details of each closure will be publicised in advance.
