Nothing unplanned in the National Highways feed for this road right now. Roadworks and planned closures are listed separately.
This page lists unplanned incidents only: collisions, breakdowns and obstructions reported on the M4. For the full picture including roadworks see M4 traffic, and for what’s shut this weekend see M4 closures.
The M4 runs west out of London past Heathrow, Reading and Swindon, over the Prince of Wales Bridge and into South Wales as far as Pont Abraham. The smart-motorway section between J3 and J12 and the Brynglas Tunnels at Newport are its two best-known bottlenecks. Welsh-side incidents come from Traffic Wales; English-side from National Highways. Everything refreshes every 5 minutes.
