Overnight closures are planned on the M4 this weekend for smart motorway works.

National Highways said the motorway will be shut in both directions between Junction 6 (Slough/Windsor) and Junction 5 (Langley) overnight on Friday (Dec17), Saturday and Sunday.

The closures will be in place from 8pm until 6am the following morning.

The conversion of the M4 to a smart motorway has been completed between Junction 8/9 (Maidenhead) and Junction 12 (Calcot Interchange).

Construction is continuing on the £848 million project between Junction 3 (Hayes & Harlington) and Junction 8/9 (Maidenhead).
