M4 westbound closure planned for overnight repair work in Wiltshire

Summarised from 3 outlets · Updated 5 Nov, 12:25 · Archive

The M4 westbound between junctions 16 and 17 in Wiltshire will close overnight from 12 to 13 November for a £20 million improvement scheme.

The M4 westbound carriageway between junctions 16 and 17 in Wiltshire will fully close overnight from Tuesday, November 12, to Wednesday, November 13. National Highways will use this closure to install a new 50mph speed limit and establish two-lane running as part of ongoing repair work following a landslide.

The improvement scheme, which began on 5 October, is budgeted at £20 million and is expected to continue until February. During the overnight closure, westbound traffic will be diverted through Royal Wootton Bassett via the A3102, then onto the A4 to Chippenham, and the A350 to the junction 17 roundabout. Heavy goods vehicles will follow a separate route via Cirencester and Malmesbury.

Once the closure is complete, the M4 westbound will remain reduced to two lanes under a contraflow system, with lane one and the hard shoulder closed. A 50mph speed limit will be in place from 13 November to 17 February to protect both drivers and workers involved in the repairs.

National Highways has advised drivers to allow extra time for their journeys, particularly during peak hours, as minor delays are expected during the work period.
