The Dover TAP on the A20 has been introduced, just hours after measures were eased on the M20.

The traffic management system was implemented just before 8am today (Friday) due to heavy freight volumes.

Kent Highways management centre says it is to prevent Port-bound traffic from disrupting the local road network and the A20 through Dover town.

It comes as 'Brock Zero' was scaled back on the M20 with Junction 10a for Ashford and 11 for Hythe re-opened, though the contraflow system remains.

The coastbound section had been shut for more than a week from Junction 8 (Maidstone services and Leeds) to allow lorries to be stacked on the motorway while they awaited clearance to Channel crossings.

Operation Brock contraflow returned last night, following an announcement from National Highways, allowing M20 road access for tourists, local traffic and non-EU bound freight.

Dover TAP (Traffic Assessment Project) 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.

The A20 Roundhill Tunnel was closed coastbound at around 10.30am to prevent stationary queues inside the tunnel from M20 J13 (Folkestone) to A260 Canterbury Road (Hawkinge/Alkham).

It comes as waiting times of up to one hour are reported for freight at Eurotunnel in Folkestone because of high demand.
