The M4 westbound between Junctions 16 and 17 near Swindon will close overnight on November 14 and 15 for improvement works.

National Highways has rescheduled an overnight closure of the M4 westbound between Junctions 16 and 17 near Swindon. The closure, originally planned for November 12 to 13, will now take place from 9pm to 6am on November 14 and 15, followed by further overnight closures on November 21 and 22. The work is part of a £20m improvement scheme for the motorway.

Mottorists will be diverted via Chippenham and advised to follow signs rather than sat-nav. Following the closures, two westbound lanes will remain open under a 50mph speed limit from November 15 until February 17. Eastbound traffic will continue to run on three lanes as normal during this period.

The improvement scheme includes repairing a ground stability issue caused by a landslide earlier this year that made part of the eastbound hard shoulder unusable. National Highways will stabilise 600 metres of embankment to restore the shoulder. The work also involves renewing four bridges and upgrading 1.3 miles of safety barrier.

Contractors will move around 25,000 tonnes of earth and other material before backfilling with 19,500 tonnes of stone sourced from a nearby quarry. National Highways said the improvements are expected to add no more than two minutes to journey times and will help 'maintain the long-term safety, resilience and reliability' of this important route. The embankment stabilisation must be completed before bridge repairs begin in autumn 2027.
