Commuters across Gloucestershire and Somerset are facing severe disruption this morning after a serious road traffic collision involving a motorbike and a car.
Crash Details and Road Closures
The incident occurred on the A46 near Cold Ashton in Gloucestershire during the early hours of Friday, November 28, 2025. The collision has led to the closure of the A46 in both directions between the M4 junction 18 and the A420.
Avon and Somerset Police are leading the response to the incident, with officers from National Highways present at the scene to manage traffic. The closure is expected to remain in place throughout the morning rush hour, causing significant backlogs.
Widespread Travel Disruption
The closure of this key commuter route has had a knock-on effect across the local road network. Heavy traffic is now being reported on the M4 in both directions near junction 18 for Bath.
While official diversions are in operation, these alternative routes are also becoming heavily congested. Drivers are experiencing long delays on local roads throughout Gloucestershire and Somerset as traffic seeks a way around the closure.
Ongoing Situation and Advice
With peak travel times underway, traffic queues are anticipated to worsen. Motorists are being strongly advised to avoid the area if possible and to allow for considerable extra journey time if travel is essential.
The authorities have not yet indicated when the A46 is expected to reopen. Commuters and other road users should seek alternative travel plans and monitor live traffic reports for the latest information on this developing situation.
