M4 weekend closure for smart motorway works

The M4 will be shut in both directions between Junctions 6 and 8/9 this weekend while planned works are carried out on the smart motorway.

National Highways has said the closure between between Junctions 6 (Slough-Windsor) and 8/9 (Maidenhead) will start after 8pm Friday, February 4 February and the motorway will reopen by 6am on Monday 7 February.

The upgrade of the M4 motorway between junctions 8/9 and 12 is finished and all temporary restrictions have now been removed.

National Highways has said the key changes motorists will see are as follows:

• You will be able to drive between junctions 8/9 and 12 at the national speed limit.
• There will be variable speed limits at certain times to smooth out traffic and tackle frustrating stop-start congestion.
• The hard shoulder has been converted to a new fourth traffic lane in each direction, boosting capacity by a third on this vital route between London, the south west and Wales.
• If you get into difficulty, you are able to use one of 29 places to stop in an emergency which include emergency areas.
