On March 18, 2026, the M5 motorway is closed in both directions between junctions 18 (Avonmouth) and 19 (Portbury) due to a welfare-related incident. This closure has led to significant congestion in the area, prompting authorities to advise motorists to seek alternative routes.
Avon and Somerset Police confirmed the closure, stating, “The M5 is closed in both directions between junctions 18 (Avonmouth) and 19 (Portbury) due to a welfare-related incident.” As traffic builds up, drivers are experiencing delays and are encouraged to find other routes to avoid the affected section.
In response to the closure, Bristol City Council has switched off the Clean Air Zone to facilitate diversions. This means that cameras monitoring the Clean Air Zone will be suspended during the closure, allowing drivers to navigate without incurring charges.
For those whose vehicles are diverted into the Clean Air Zone due to planned roadworks, Bristol City Council has stated, “If your vehicle is diverted due to planned roadworks into the Clean Air Zone and you follow the signed diversion route, you will not have to pay the zone charge.” This provision aims to alleviate the financial burden on drivers forced to change their routes.
Additionally, drivers who have already paid a zone charge due to road diversions can apply for a refund. Those who received a Penalty Charge Notice as a result of the diversion can appeal the fine, providing some relief amid the ongoing disruption.
National Highways has issued guidance for drivers navigating the area. Southbound drivers are advised to follow the hollow circle symbol on road signs, while northbound drivers should look for the solid triangle symbol. This signage is crucial for ensuring that motorists can safely and efficiently reroute around the closure.
As of now, the M5 remains closed, and traffic conditions continue to evolve as authorities manage the situation. The closure is significant not only for local commuters but also for those traveling longer distances, as it impacts major routes in the region.
The sequence of events surrounding the M5 closure is critical for all involved, particularly for local residents and businesses that rely on the motorway for access and transportation. The ongoing incident highlights the importance of effective communication and contingency planning in managing traffic disruptions.
