This evening, an accident closed a lane anticlockwise near Junction 2 at the Darenth interchange but as of 8pm it had been cleared.
At the peak of the hold-ups, there were hour-long delays this afternoon with motorists stuck in stop-start traffic.
It was causing significant congestion on surrounding roads, particularly in Dartford and Greenhithe, as drivers prepared to leave the county for the school holidays.
