Motorists are being advised the westbound slip road at Junction 16 of the M4 will be closed to allow contractors to resurface the road.
The closure will take place from 20:00 and 06:00 tonight (Monday 21st August) and will also close on Tuesday and Wednesday this week.
There will be a diversion in place which will see drivers travel along to Junction 17 (Chippenham) and double back to the eastbound exit at Junction 16.
The slip road will also be closed early September to allow for the remaining lanes to be resurfaced.
