Traffic on the M5 motorway near Bristol has been severely affected as police have closed the road in both directions due to a welfare-related incident. This closure spans from Junction 18 (Avonmouth) to Junction 19 (Portbury) and is prompting significant delays for motorists. Emergency services are currently on-site, addressing the situation, while congestion has built up for several miles in both the southbound and northbound lanes.

In response to the closure, National Highways has put in place a diversion route for drivers heading northbound. The recommended route instructs drivers starting at Junction 21 to head east on the A370 and then continue north on the A4, which has been confirmed by the Bristol Council to have the clean air zone temporarily suspended during this incident. Traffic monitoring services have reported that delays and congestion persist, with the situation developing as emergency services continue their work.

As the incident is considered welfare-related, and not a vehicular accident, police have not provided specific details about the individual involved. However, the significant operational response from emergency services indicates the seriousness of the situation. Motorists are advised to avoid the area where possible, and updates will continue to be released regarding the status of the motorway as more information becomes available.
