Drivers heading towards London on the A40 are facing delays this morning after a crash.

All lanes have reopened but there are still tailbacks on the eastbound carriageway follwing the incident.

The crash occurred at about 7.30am at the traffic lights outside Thornhill Park and Ride.

Thames Valley Police spokeswoman Connie Primmer said it was a damage-only collision but the road remained blocked while police waited for the vehicles to be removed.
