Operation Stack

What is Operation Stack?

Operation Stack is a procedure that uses parts of the M20 to queue up to 3,000 heavy goods vehicles (HGVs), travelling towards the Continent, to avoid causing gridlock on Kent's roads. It is implemented whenever there is an urgent need to inhibit the flow of freight traffic to Eurotunnel Le Shuttle and the Port of Dover due to capacity restrictions.

  • Stage 1: Coastbound junctions 8 to 9
  • Stage 2: Coastbound junctions 8 to 11
  • Stage 3: London bound junctions 9 and 8
  • Stage 4: London bound junctions 11 and 8

Passenger vehicle traffic is normally diverted onto the A20 and other smaller roads. To help make your journey go smoother and for the latest Operation Stack status update, please visit kent.gov.uk.
