Operation Brock is a set of measures implemented by Highways England 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.

Phase 2 & 3 - Use the M20. Between junctions 8 and 9 you’ll use the two-way contraflow system on the London-bound carriageway. A 50mph limit will be in place.
