M4 westbound closed between Junction 11 and Junction 12 due to serious traffic collision

A serious road traffic collision on the M4 between junctions 11 and 12 has caused severe delays that are expected to last for several hours.

The road between J11 (Reading) and J12 (Theale) is closed westbound, although eastbound has now reopened apart from the outside lane.

Thames Valley Police, Fire, Ambulance Services and National Highways Traffic Officers are on scene dealing with an incident involving a car and a van that occurred shortly before 8.45am today. As a result of the collision one car caught fire.

Drivers travelling westbound on the M4 are advised to follow the hollow square diversion signs which will take them off the motorway at J11 to join the A33, before getting on the A4 and re-joining the M4 at J12.

Eastbound drivers should follow the hollow circle diversion signs and follow the above route in reverse.

Highways England are stating that the M4 eastbound should return to normal between 12.30pm and 12.45pm, and westbound between 4pm and 4.15pm.
