Road users are advised that the coastbound M20 is currently closed between junctions 9 and 10 near Ashford following an earlier serious incident involving four HGVs.
The closure is expected to remain throughout the morning peak period and drivers heading for Dover are advised to use the A2 and M2.
Due to refurbishment of the Stockbury Viaduct, there is a contraflow system and temporary 40mph speed limit in operation at junction 5 of the M2, near Sittingbourne.
The operation to remove the HGVs from the carriageway has begun. Due to the size of the vehicles this is expected to take some time.
As a result of the incident there was a large diesel spillage across the carriageway which may have damaged the road surface.
Once the vehicles have been removed the condition of the carriageway will be assessed and any necessary resurfacing will be carried out, which again could take several hours
