There were long delays for drivers on the M25 after a crash near the Dartford Tunnel.
Traffic was held up getting into Essex following the accident earlier this afternoon, with queues of about eight miles at one stage.
Two lanes were closed following the smash, along with the right-hand tunnel. They have all been reopened but the gridlock remained into the evening.
At its worst, congestion stretched back past Junction 3 at the Swanley interchange to Junction 4 at Orpington.
Traffic through Dartford and along the A2 between Dartford Heath and the Ebbsfleet interchange was also affected, as drivers attempted to join the M25 at Darenth.
