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).
The Government has announced the results of the smart motorways safety audit. The programme will continue and there is an 18 point plan to improve safety.

NEXT WEEKEND FULL CLOSURE 24-27 APRIL 2020: The M4 between junctions 6 and 8/9 will be closed in both directions from approximately 8pm Friday 24 April until 6am on Monday 27 April 2020 for the installation of a new bridge deck at Marsh Lane. Traffic will be diverted to the A308M, A308, A332 and the A355. Strategic diversions will also be in place in the wider region using the M25, M3 and M40.
There is only one overnight full closure this week:
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.
