Operation Stack activated on coast bound M20 between junctions 8 and 9 in Kent

The strike started at 7am this morning, and is expected to last for 24 hours.

Operation Stack has been activated between junctions 8 for Maidstone East and 9 for Ashford and is expected to be in place until the backlog clears.

Operation Stack is where parts of the M20 are closed to queue lorries that are travelling towards the continent, to avoid causing gridlock across Kent’s road network.

All Europe-bound freight traffic should head towards Dover on the M20 to join the queue at junction 8. Local and non-freight traffic must leave the M20 at junction 8.

It is expected that the M20/A20 and M2/A2 approaches will be busy for tourist, freight and local traffic for the rest of the day. The diversions for non-freight traffic are:

  • If you’re heading to Eurotunnel, use the M20 and A20 and follow the hollow circle diversion symbol
  • If you’re heading to the Port of Dover, use the A2, M2, A2 towards Dover.

Drivers are advised to:

  • Plan their journeys and allow extra time if required
  • Check travel conditions before setting out and, where it is safe to do so, during journeys
  • Make sure you have some supplies for your journey, such as food and water
