Vehicles travelling northbound over the Dartford Crossing are currently experiencing delays of over 90 minutes.

This is due to a crash, involving a lorry and up to three cars, which closed the anti-clockwise carriageway of the M25, between junctions 30, Thurrock, and 29, Upminster earlier today.

The road has now reopened.

Essex Police and other emergency services attended the scene.
