The lifting of lockdown restrictions from 19 July has triggered the next deployment of the moveable barrier system on the M20 in Kent in preparation for increased traffic numbers, Highways England has confirmed.

Operation Brock is part of a series of measures to improve Kent’s resilience in the event of disruption to services across the English Channel.

As with previous deployments, Operation Brock will keep the M20 open in both directions by using a contraflow road layout on the M20 London-bound carriageway between junctions 9 and 8 (from Ashford to Maidstone) and directing lorries heading for mainland Europe onto the coastbound carriageway, where they can be queued if necessary.

Nicola Bell, Highways England Regional Director, said: “The lifting of the lockdown restrictions will inevitably mean more travel across to France from 19 July and, we, along with our Kent Resilience Forum partners, have taken the decision to reinstall the moveable barrier on the M20 to prepare for this.”

While some people will not be happy with the return of Operation Brock, she went on, it is necessary to prepare for an increase in HGVs and passenger traffic. Ms Bell concluded that the deployment of the barrier on the M20 will be kept under constant review and will be removed as soon as possible.
