M5 Motorway Closed: Police Incident and Diversion Route in Bristol (2026)

A critical situation has unfolded on the M5 motorway near Bristol, prompting a full closure and a diversion route. But here's the catch: it's not just any incident.

Emergency services are on the scene, and Avon and Somerset Police have revealed it's a welfare concern. The southbound side of the M5 is closed between junctions 18 and 19, but the northbound side remains open.

National Highways has confirmed a diversion route is active. Here's the full route for those travelling southbound: exit at J18A onto the Avonmouth Spur road, take the slip road to Portway roundabout, then the A4 south (through the clean air zone, which has been temporarily switched off), to Gurney roundabout. From there, take the A4174 South Bristol Link road to Lime Kiln roundabout, then the A38 south to East Brent. At East Brent roundabout, take Bristol Road, and at the next roundabout, rejoin the M5 at J22.

This incident has sparked curiosity and concern among locals. And this is the part most people miss: it's not just about the closure, but the potential impact on the community and the environment. With the clean air zone temporarily disabled, what are the implications for air quality?

What are your thoughts on this situation? Do you think the authorities handled it well, or could there have been a better approach? We'd love to hear your opinions in the comments below!
