M4 Roadwork update - w/c Sep 20th


There are the following overnight carriageway closures scheduled this week:

  • The M4 is due to be closed in both directions only overnight next weekend between junctions 6 (Slough) and 8/9 (Maidenhead) from 8pm until 6am each day from Friday 24 until the following Monday. Normal access will resume from 6am on Monday 27 September.


In the event of poor weather conditions or other issues out of our control, planned work may be postponed at short notice. Contingency bookings are also in place, but these are only used if previously planned work is delayed and there is no clash with other closures. If work completes on an earlier day the motorway may not close, or if work completes ahead of schedule the motorway may reopen early. Signage will be in place on the network to notify of closures and diversions.


Best regards
