Operation Brock Deployed - Likely to impact Brenley Corner

The Operation Brock contraflow system on the M20 in Kent will be deployed overnight tonight – Tuesday 13 December – ahead of the Christmas period.

The contraflow arrangement – originally planned to be deployed overnight on Sunday but postponed due to heavy snow in the area – will be in operation when the M20 reopens at 6am on Wednesday morning (14 December).

Operation Brock is part of a series of measures to improve Kent’s resilience and ensure the smooth flow of traffic through the region in the event of disruption to services across the English Channel.

To set up the contraflow system, the M20 will be closed from 9pm tonight until 6am tomorrow morning (14 December) London bound M20 between junctions 9-8 and coastbound M20 between junctions 7-9.

A fully signed diversion route will be place while the M20 is closed overnight.

When the M20 reopens with the Brock contraflow in place all signs and signals should be followed.
