Today’s disruption on the M4 follows the closure of the Severn Bridge on the M48 last night, which is the other major route over water into England.
In a statement at midnight, Traffic Wales confirmed the Severn Bridge remained closed in both directions due to high wind speeds.
“We will continue to monitor this throughout the morning. Traffic will be diverted via the #M4 #PrinceofWalesBridge,” it said.
Traffic Wales confirmed the bridge reopened this morning, responding to frustrated drivers.
One motorist had asked the organisation on X: “Hi, is there an update on this? The detour makes a 8 mile journey a 31 mile journey, the price of petrol its nearly unaffordable.”
