Dover TAP is now in place at Aycliffe.

The restriction, called the Traffic Access Protocol, has been put on the section of the coastbound stretch A20 because of a large volume of lorries.

Kent County Council highway officials announced this at 1.25pm today.

A council spokesman said the measure was implemented "to prevent Portbound traffic from disrupting the local road network and the A20 through Dover town."

Dover TAP is a temporary traffic management system which queues port-bound lorries on the nearside to prevent congestion in the town.

Traffic lights hold back lorries until space at the Port of Dover becomes available.

It also means a 40mph speed restriction for all vehicles approaching the port and town.
