M4 Motorway remains closed following serious collision

The M4 is currently closed from J1 to J3 with delays of at least 60 minutes covering several miles of the westbound carriageway. This closure is due to a road traffic collision and Highways England has resources deployed and are working hard to restore normal conditions as soon as possible. Officers from the Met Police are also in attendance at the incident that happened during rush hour. The London air ambulance has also landed on the westbound carriageway. For traffic approaching the closure locally, you are advised to expect disruption with extra journey time and may potentially have to re-route your journey. If travelling towards this area from much farther afield, you may wish to change your strategic route, allow extra travel time and follow guidance from our on-road variable message signs and media.
