A section of the M4 will remain closed this morning following a serious crash overnight. 

Wiltshire Air Ambulance was called after a car and a light goods vehicle crashed on the westbound carriageway between Hungerford (J14) and Swindon (J15) at around 1am.

National Highways provided an update on Friday morning to say that both carriageways were closed at the time to allow the air ambulance to land on the road.

The organisation added that while the eastbound carriageway was reopened at 3am the westbound carriageway is still closed while Wiltshire Police carry out an investigation.

Assessments are being made of the road surface and if any significant resurfacing is necessary, the westbound carriageway is expected to remain closed throughout the morning commute.

A signed diversion remains in place and motorists are being advised to allow extra time for their journeys and follow the hollow square diversion symbol:

  • Leave the M4 at J14.

  • At the roundabout, take the first exit and join the A338. Follow for approx 3 miles

  • At the A4 mini roundabout turn right onto the A4 towards Hungerford avoiding Hungerford town centre.

  • After a short distance to the next roundabout take the 2nd exit into Charnham Park.

  • Turn right onto the B4192 and follow for approx 13 miles through Aldbourne to the A419 roundabout

  • Take the first exit and join the A419, continue to rejoin the M4 westbound at Jct 15
