A National Highways spokesperson confirmed the westbound closure was necessary because of the vehicle fire. The cause of the incident and whether anyone was injured had not been confirmed in the reports reviewed.
Drivers Warned of Disruption
The closure affected a busy motorway interchange serving Bristol and surrounding communities. Drivers travelling towards South Wales were advised to allow additional time for their journeys and monitor official traffic updates.
The M4 and M5 connect with the A4174, which serves as a key route around Bristol. Disruption at the motorway interchange can therefore affect traffic on nearby roads, although a separate accident on the A4174 was not confirmed in the available reports.
Motorists should follow diversion signs and instructions from emergency services while the incident is managed.
