All emergency services are on the scene, National Highways said.
Driver of one of the vehicles sustained a leg injury, Kent Police said.
The force told Metro: ‘Patrols and highways officers are currently at the scene where one of the vehicles has overturned and the driver is reporting a leg injury.’
Traffic is queueing in both directions, causing long delays stretching towards Rochester and Dartford in the west.
Traffic analyst Inrix warned: ‘Congestion to Pepper Hill back past Gravesend, and over two miles of onlookers back to the M2 at Strood.
‘Also heavy on the A226 diversion into Higham.’
