M4 smart motorway work closure update for the week commencing 22 June 2020

Work to improve journeys by converting the M4 into a smart motorway between Junctions 3 at Hayes to Junction 12 at Theale continues this week. 24 hour narrow lanes and a 50mph speed restriction are in place for sections of this stretch of the M4. Carriageway and slip road closures are planned as follows, all fully closed overnight (traffic management will usually be rolled out from 9pm and taken off by 6am).

  • NEXT WEEKEND FULL CLOSURE, JUNCTIONS 4B TO 5: The next scheduled weekend closure is between junctions 4b and 5 over the weekend of 26-29 June 2020. The closure will begin on Friday 26 after 8pm and complete by 6am on Monday 29 June 2020. Traffic will be diverted to the local highway network over the weekend.
  • Our June news bulletin is out with details of our weekend closures up to the end of September, read it here.....

    There are the following overnight closures next week:

  • The M4 eastbound will be closed overnight between junctions 11 (Reading) and 10 (Wokingham) on Thursday 25 June 2020. Clearly signed diversions will be in place utilising the B3270, A3290 and the A329M.
  • The M4 eastbound will be closed overnight between junctions 12 (Theale) and 11 (Reading) on Wednesday 24 June 2020. Clearly signed diversions will be in place utilising the A4 and A33.
  • The M4 westbound will be closed overnight between junctions 11 (Reading) and 12 (Theale) on Tuesday 23, Wednesday 24, Thursday 25, Friday 26 June 2020. Clearly signed diversions will be in place utilising the A33 and A4.

  • Slip road / junction closures for next week are as follows:

  • Junction 4 - the westbound carriageway will be closed overnight between the entry and exit slip roads on 26 June.
  • Junction 4b - the westbound link road from the M25 will be closed overnight on 23 June.
  • Junction 8/9 - the westbound entry slip road will be closed overnight on 24 June.
  • 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. The project is continuing but all our work is under careful review in response to the Covid-19 outbreak and safety measures are in place on site to protect workers, their families and the public.
