About the M4 motorway
The M4 is one of the UK’s busiest and most important motorways, running around 189 miles from London west through Reading, Swindon and Bristol, across the Severn into South Wales to Newport, Cardiff, Swansea and Pont Abraham. It connects with the M25 (J4b), M32 (J19), M5 (J20) and the M48 Severn route (J21/J23). With heavy commuter and freight traffic, roadworks and incidents are common — so it pays to check the latest M4 traffic news before you set off.
M4 Traffic gathers the newest M4 traffic reports and updates in one simple, mobile-friendly place, refreshed throughout the day, so you can plan your route and avoid the worst of the queues.
