A section of the M4 westbound remains closed this morning while investigations continue into a serious crash between a car and a lorry.

Traffic was stopped on the carriageway between Hungerford (Junction 14) and Swindon (Junction 15) in the early hours of this morning.

Wiltshire Police and air ambulance are both believed to remain in attendance at the scene.

Cars at the back of the queue in Wiltshire began to be turned around just before 4am, National Highways said.

The agency has outlined a diversion route for drivers on its website.

  • Use the first exit and join the A4155 Little Marlow Road.
  • Continue over the next roundabout and follow to the A404 Marlow Interchange.
  • At the roundabout, use the third exit to rejoin the A404 southbound.

Around three miles of congestion is expected, with 30 minutes of delays for drivers.
