A serious rush-hour crash involving a lorry and a road-sweeper on the M25 is causing eight-mile tailbacks at the Dartford crossing this morning.
Part of the Kent section of the M25 is closed anti-clockwise following the crash between junction five for the M26 and junction four for Orpington - adding hours to rush hour journeys this morning.
The road has been closed anti-clockwise since 5.25am while emergency services work at the scene.
It will be closed for the 'foreseeable future', say Highways England, who have promised to release the trapped traffic.
Vehicles were originally held on the clockwise carriageway from 6.20am, but it has since been reopened with a lane three closure.
