• Operation Brock

  • 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.

  • Drivers of cars, coaches and non-HGV vehicles

    Phase 1 - Use any available major route. If you 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.

    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

    Phase 4 - You won’t be able to use the M26. Follow the same procedure as for Phase 2 & 3.
