What is Operation Brock?
Operation Brock is a set of measures to keep the M20 open in both directions between junctions 8 and 9 in the event of disruption to services across the English Channel, by using different holding areas.
The queuing system only applies to lorries heading to mainland Europe from Kent. All other drivers should check conditions before setting out and, if they’re crossing the channel, check with their service operator for updates.
Phase 1 – In the event of excessive disruption to services across the English Channel, improved holding capacity in the Port of Dover and Eurotunnel, as well as on the A20 approach to the port (Dover TAP), would be used.
Phase 2 – If phase 1 capacity is reached, we will start queuing Europe bound lorries that are 7.5 tonnes and over on the coast bound section of the M20 between junction 8 and 9 with cars and other vehicles using a contraflow on the London-bound carriageway.
Phase 3 – If phase 2 becomes full, lorries heading for Port of Dover will be directed to Manston Airfield, while the M20 is used to hold traffic for Eurotunnel. Traffic lights on the A256 after Manston Airfield will help to manage traffic arriving at the port.
Phase 4 – If the M20 holding area and Manston becomes full, the M26 could be used to hold additional lorries heading for Eurotunnel.
