M4 motorway shut down due to high winds in south Wales

Severe weather conditions have resulted in the closure of the M4 motorway in south Wales, affecting traffic significantly.

Severe winds have led to the closure of part of the M4 motorway in south Wales. The Kenfig Viaduct is shut in both directions from Junction 37 at Pyle/Porthcawl to Junction 38 at Margam. This decision follows a broader weather warning affecting the entire region, with wind speeds reaching up to 70 mph.

Impact on Traffic

Traffic is currently being diverted off the motorway, resulting in long queues in both directions. The closure was implemented by Traffic Wales South at 12 PM today, citing expected high winds as the primary reason. Authorities have indicated that the closure will remain in effect “until further notice,” creating uncertainty for commuters and travelers.

As motorists navigate the diversions, congestion is expected to worsen, particularly during peak travel hours. Local police are advising drivers to plan ahead and consider alternative routes to avoid delays. The situation remains dynamic, and updates will be provided as more information becomes available.

Wider Weather Conditions

The high winds have not only impacted the M4 but have also resulted in the closure of the M48 Severn Bridge due to safety concerns. This closure adds another layer of complexity to travel in and out of Wales, as the bridge serves as a critical link between England and Wales.

With the weather warning in place, residents are urged to stay indoors if possible and avoid unnecessary travel. Emergency services are on high alert to respond to any incidents caused by the adverse weather conditions.

Live Updates

As of now, the motorway remains closed, and traffic is being diverted. Long queues have formed as motorists adjust to the road closures. Emergency teams are monitoring the situation continuously, and further updates will be provided as they come in.

UPDATE AT 12:45: The road is confirmed closed in both directions due to high winds. Traffic is being diverted.

Our reporters on scene confirm: Authorities are actively managing the situation and will continue to update the public as conditions evolve.
