Police officers and emergency services workers were deployed on a stretch of the M4 westbound on Friday morning, bringing traffic to a complete standstill. All lanes were closed between junction 42 (Earlswood) and junction 43 (Llandarcy) following an incident.
One Lane Reopened, Delays Persist
One lane was later reopened, but Traffic Wales warned drivers to plan accordingly and expect significant delays. A spokesperson for the organisation said: "M4 between J42 Earlswood and J43 Llandarcy travelling Westbound. Traffic is currently on stop. There are long delays in the area. Allow extra time for your journey."
Police and traffic officers were seen in the area live, as reported by Catherine Mackinlay and Holly Morgan. The incident occurred on Friday, June 26, 2026, with updates provided throughout the morning.
Impact on Drivers
Drivers were urged to avoid the area if possible and to allow extra time for their journeys. The closure caused long queues and delays for motorists travelling westbound on the M4. Traffic Wales continued to monitor the situation and provide updates as lanes reopened.
