At midday, there are 30 minute delays on the coastbound M20 junction 11a (Euro Tunnel) exit slip road and 15 minute delays on the coastbound A20 between Folkestone and Dover.
As a result of the congestion on the coastbound A20, the coastbound entry slip road at junction 13 has been closed to prevent queuing traffic forming in the Roundhill Tunnel. A diversion is in place via local roads.
Drivers are advised to check conditions before setting out and plan their journeys to allow extra time if required.
