M4 set to stay closed throughout rush hour with huge queues after serious collision

Motorists are being warned of long delays and to avoid the M4 following a serious crash which is expected to stay closed for some time and well into rush hour. The motorway is closed in both directions between junction 18 for Bath[1] and junction 19 for Bristol[2] with delays of 45 minutes above usual journey times in both directions approaching the closure points. There is congestion to halfway to J17 (Chippenham) on the eastbound side, and just past J20 (Almondsbury Interchange) on the westbound side.

The motorway is expected to remain closed for some time with police, fire, and the air ambulance all on the scene. Officers from Avon & Somerset Police, Gloucestershire Fire and Rescue Service, South West Ambulance Service and Great Western Air Ambulance Charity are all in attendance. National Highways Traffic Officers are also at scene assisting the emergency services with traffic management.

Avon and Somerset Police have warned motorists to avoid the area. They added the motorway is expected to remain closed for some time. National Highways added: “Due to the serious nature of this incident police collision investigations will be taking place, once these are complete National Highways service providers will complete clear up work.

There is currently no estimate for when the road will re-open.” Arrangements are being made to release traffic caught within both closures via the rear of the queue. Due to the volume of traffic this may take some time, National Highways added.
