A woman in her 70s has died following a tragic crash on the M5 in Somerset, prompting a major motorway closure and a police appeal for witnesses.

The fatal collision, involving a lorry and a pedestrian, occurred shortly before 3am on Sunday morning between junctions 23 (Dunball) and 24 (Bridgwater) on the northbound carriageway.

Emergency services, including police, ambulance and fire crews, rushed to the scene after the crash was reported at 2.48am. Despite their efforts, the woman was pronounced dead at the scene. Her next of kin have been informed and are being supported by specially trained officers.

In a statement, Avon and Somerset Police confirmed: “A woman has died after a collision on the M5 near Bridgwater this morning. The incident, involving a pedestrian and a lorry, was reported at 2.48am on the northbound carriageway between junctions 24 and 23. Officers, along with the ambulance and fire services, attended, but sadly the woman, aged in her 70s, was pronounced deceased at the scene. Our thoughts are with her family at this difficult time.”

The motorway was closed in both directions following the incident to allow for a full forensic investigation. The southbound carriageway reopened earlier this morning, but the northbound side remains shut and is expected to stay closed for several more hours.

National Highways said: “The road will be closed this morning to allow for Police collision investigation works to take place.” A diversion route has been established, with drivers urged to follow the solid triangle diversion symbols on signs.

Police are now appealing for any witnesses or drivers with dashcam footage from the area around the time of the crash to come forward.

Anyone with information is asked to contact Avon and Somerset Police via 101, quoting log 132 of March 23.
