The traffic scheme, which was in place to manage the flow of freight and tourist passengers heading across the Channel via Eurotunnel and the Port of Dover over the Spring Bank Holiday, has been in place since 21 May.
The contraflow was initially activated following data from the Department of Transport and booking information showing peak periods of travel at the beginning of the school half term.
National Highways will remove the Brock contraflow between Junctions 9 and 8 overnight on Sunday 4th June, which means diversions will be in place for both carriageways during that time.
When Operation Brock is removed, the 50mph speed limit and traffic management will remain London-bound for the time being to allow work on the M20 by National Highways to resume.
Simon Jones, Strategic Lead of the KRF said: “Last weekend saw very high tourist numbers heading to the Port of Dover and Eurotunnel, as anticipated by the cross-channel providers and the Department for Transport.
“Operation Brock did the job we needed it to do in holding back freight from the A20 into Dover, allowing local traffic to continue to flow, and avoiding delays on the local road network and, indeed, the main routes to the port.
“As always, we thank everyone for their patience and for understanding that, by using the contraflow, we were able to keep Kent moving during the half-term getaway. Our aim is always to keep the county’s roads safe and to help residents, road users and businesses reach their destinations as quickly as possible.”
