Operation Brock

Last updated: 15 April 2019

Operation Brock is currently: Inactive

Operation Brock will remain inactive until further notice, but the situation will be kept under review. Operation Brock remains available for use as an alternative to the older Operation Stack, and offers significant improvements by keeping the M20 open to traffic in both directions.

As Brock is inactive, the road will be operational as follows:

  • All traffic heading coast-bound will be able to use the three-lane coast-bound carriageway. The national speed limit will apply, except for two short sections of 50mph close to junctions 8 and 9 where work areas for the cross-overs have to be retained.
  • All London-bound traffic will use the hard shoulder and lane 1 on the London-bound carriageway. The speed limit will be 50mph. Average speed cameras will remain in operation.

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. All other drivers should check conditions before setting out and, if they’re crossing the channel, check with their service operator for updates.

Phase 1 – In the event of excessive disruption to services across the English Channel, improved holding capacity in the Port of Dover and Eurotunnel, as well as on the A20 approach to the port (Dover TAP), would be used.

Phase 2 – If phase 1 capacity is reached, we will start queuing Europe bound lorries that are 7.5 tonnes and over on the coast bound section of the M20 between junction 8 and 9 with cars and other vehicles using a contraflow on the London-bound carriageway.

Phase 3 – If phase 2 becomes full, lorries heading for Port of Dover will be directed to Manston Airfield, while the M20 is used to hold traffic for Eurotunnel. Traffic lights on the A256 after Manston Airfield will help to manage traffic arriving at the port.

Phase 4 – If the M20 holding area and Manston becomes full, the M26 could be used to hold additional lorries heading for Eurotunnel.


Drivers of goods vehicles over 7.5 tonnes

Drivers of vehicles of 7.5 tonnes or more heading towards mainland Europe via Port of Dover or Eurotunnel need to follow queuing arrangements. Regardless of your end destination, check conditions before setting out and follow all signs and signals.

Instructions for lorry drivers and other goods vehicles over 7.5 tonnes will be clearly signed, actively managed and monitored at every step. If you don’t follow the instructions you may be stopped and will be delayed.

The holding areas are all temporary and will be stood down as soon as they are no longer needed. All will be safe and have access for emergency services. Manston Airfield will be secure and have water, toilets, showers and rubbish bins.


Phase 1
Use any available major route. Maidstone Roadchef services at junction 8 are open as normal.
Phase 2
Use the left-hand lane of the M20 between junctions 8 and 9. You’ll be held at lights until space at the Eurotunnel becomes available. The speed limit will be 30mph. Maidstone Roadchef services at junction 8 are open as normal.
Phase 3
Junction 8 of the M20 will be closed. Operation Brock officials will confirm you’re travelling to Eurotunnel and guide you to enter the M20 junction 8-9 goods vehicle area on the coastbound carriageway. You’ll be held at lights until space at the Eurotunnel becomes available.
Phase 4
You’ll be guided by signs to a goods vehicle area on the M26. You’ll be held at lights on the M26 until space on the M20 junction 8-9 becomes available. You’ll then be guided by Operation Brock officials into the M20 junction 8-9 goods vehicle area. You’ll be held at lights until space at the Eurotunnel becomes available.


Phase 1
Use the A20 and follow the Dover Traffic Access Protocol (TAP): only use the left-hand lane and keep within the 40mph speed limit. You’ll be held at lights until space at the port becomes available. Maidstone Roadchef services at junction 8 are open as normal.
Phase 2
Signs on of the M20 will direct you to the lane for your destination. You’ll be held at lights until space at the port becomes available. The speed limit will be 30mph. Maidstone Roadchef services at junction 8 are open as normal.
Phase 3
You’ll be directed to a holding area at the disused Manston Airport. Signs will divert you along the A249, M2 and A299 to Manston. If you’re not already on the M20, you’ll be diverted along the A2/M2/A299. Welfare facilities including water, toilets, showers and bins will be available. The area will be controlled and monitored. Once space becomes available at the port, you’ll be guided by Operation Brock officials to the A256 TAP. You’ll be held at traffic lights. You must only use the left-hand lane within A256 TAP
Phase 4
Follow the same procedure as for Phase 3.


Phase 1
Use any available major route. If you use the A20, you can use the right-hand lane. You may be stopped at traffic lights and asked to prove you’re not heading to the ports. Maidstone Roadchef services at junction 8 are open as normal.
Phase 2
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. To leave at junction 9 you must use the left-hand lane of the contraflow. A 50mph limit will be in place. You’ll re-join the normal carriageway at either junction 8 or 9, depending on your direction of travel.
Phase 3
Follow the same procedure as for Phase 2
Phase 4
You won’t be able to use the M26. Otherwise, follow the same procedure as for Phase 2


Phase 1
Use any available major route
Phase 2
Use any available major route. If you use the M20, between junctions 9 and 8 you’ll use the two-way contraflow system on the London-bound carriageway. A 50mph speed limit will be in place. Signs will guide you into the contraflow at junction 9 and out at junction 8.
Phase 3
Follow the same procedure as for Phase 2.
Phase 4
You won’t be able to use the M26. Otherwise follow the same procedure as for Phase 2.
