The M25 is closed near Heathrow Airport following a collision on Tuesday morning.
The closure is clockwise between junction 14 (Stanwell Moor/Heathrow Airport) and junction 16 (M40).
National Highways say a serious collision investigation is being carried out and that the closure “is expected to be protracted and in place for a considerable time today”.
A diversion is now in place allowing drivers to exit the M25 at junction 14 before rejoining after a stint on the M40. Motorists planning on commuting in the coming hours have been warned to avoid the area and plan an alternative route, as CCTV footage shows gridlocked traffic.
Little is known about the incident at this time, but National Highways has confirmed it was a “serious collision involving two cars and a lorry.”
Photographs from the scene seemingly show that a passenger vehicle smashed into the rear of the truck. The car appears to have suffered significant damage.
A National Highways spokesperson said: “Our East Regional Operations Centre were notified of the collision just before midnight yesterday evening. Metropolitan Police and National Highways Traffic Officers remain on scene.
“London Fire Brigade and London Ambulance Service attended. A collision investigation is being carried out, the closure is expected to be protracted and in place for a considerable time today.”
Metropolitan Police and National Highways Traffic Officers currently remain on scene as the collision investigation is carried out.
