Incident Halts Traffic on M4 Prince of Wales Bridge in Both Directions

Officials expect to clear the route by late morning.

Overview

  • Traffic on the key Severn crossing was held in both directions Sunday morning, causing queues and lane closures between J22 for the M49 and the M48.
  • Inrix first cited debris on the road, then listed barrier repairs, while National Highways referred to a crash in the area, leaving the exact cause unclear.
  • Traffic Wales called the disruption moderate and urged drivers to avoid the bridge, with lane three reported closed on both carriageways as queues formed.
  • National Highways’ live map gave an estimated clearance window between 11:45am and 12:00pm, matching updates that pointed to ongoing barrier work.
  • The Prince of Wales Bridge carries heavy cross‑border commuter and freight traffic, so even brief holds can ripple across routes in southwest England and South Wales.
