There are large queues on Kent's roads once again as lorries line up for a fourth day of delays.
Temporary signals are in place due to the bulk of transport traffic seen heading to the Eurotunnel at Folkestone and the Port of Dover.
Dover TAP, short for Traffic Assessment Project, has been implemented on the coastbound A20 at Aycliffe due to the high volumes of freight.
It was put in place for the fourth time in two weeks on Tuesday, and has been activated each day since, including today.
Kent County Council, which made the announcement from its highways control desk shortly before 7am, says this is to prevent port-bound traffic from affecting the local road network and the A20 through Dover town.
It means a 40mph speed restriction will apply to all vehicles approaching Dover from the west via the A20.
The larger volumes than usual have been attributed to the pre-Christmas rush, stockpiling and coronavirus vaccine delivery.
When traffic reaches high volumes vehicles will be held at temporary traffic lights until space becomes available.
Lorry drivers heading coastbound should remain in the left lane of the A20, from the Roundhill Tunnel all the way to the Port.
According to the Port around 9500 vehicles are travelling through each day.
Motorists are being asked to plan ahead and allow extra time for journeys.
Dover TAP is the first of five stages comprising Operation Brock, designed to maintain traffic flow in the county during busy freight periods.
In the full Operation Brock, Dover TAP will be succeeded by the M20 J8-9 contraflow system - in which lorries would use the eastbound carriageway as a holding station.
From four days from later today the M20 will shut to allow for Operation Brock preparation works.
