M4 smart motorway work closure update for the week commencing 6th May 2019

M4 junctions 10 at Wokingham to Junction 12 at Theale, Berkshire: upgrade to smart motorway

Work to improve journeys by converting the M4 into a smart motorway between Junctions 3 at Hayes and 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 closed overnight between approximately 10pm and 5am (traffic management will usually be rolled out from 9pm and taken off by 6am).

There are no full closures booked for the week commencing 6th May 2019, but there are M4 entry and exit slip road closures this week as follows, with signed diversions in place. Keep an eye out for updates on the network:

  • Junction 10 - Slip 6 (westbound entry from the A329M southbound) will be closed overnight on 7th, 8th, 9th, 10th and 13th May.
  • Junction 12 - the eastbound exit slip will be closed overnight on 8th and 9th May.
  • 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. 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.
