Delays have eased after an earlier crash near the Dartford Tunnel - after all lanes reopened.

At its height, traffic was tailed back to J4 for Orpington, which added around 40 minutes to drivers' journeys.

The crash, between J1A for Swanscombe and J31 for West Thurrock meant the left-hand tunnel was closed just after 6am for an hour, following the two lorry crash.

Traffic ealrier queued back for six miles on the clockwise carriageway at the QEII bridge.
