Kent Resilience Forum: Operation Brock Deployment April 2025

The Port of Dover and Eurotunnel are forecasting their peak tourist traffic numbers in April, as people prepare to go away for Easter.
To help keep traffic flowing through Dover, and avoid congestion on local roads in the area, the Kent and Medway Resilience Forum (KMRF) has agreed to deploy Operation Brock on the M20 for a limited period as a precaution.
Although I understand the decision to use Brock at busy times is not always popular, the contraflow system reduced the need to close the Roundhill Tunnel when queues of lorries build up, and this helps to minimise disruption on the local roads around Folkestone and Dover. The contraflow will be put out on the London-bound carriageway between Junctions 8 and 9 overnight on Wednesday 2nd April and will be removed overnight on Tuesday 22nd April. This will allow lorries to be held on the coastbound carriageway if the Dover TAP queuing system on the A20 outside Dover fills up.
As Strategic Lead for border disruption for the Kent & Medway Resilience Forum (KMRF) I want to reassure you that the focus of everyone involved in managing traffic at this busy time continues to be on keeping traffic moving, disruption to a minimum, and communities in and around Dover and Folkestone safe. We will monitor cross-channel bookings during the Easter holiday, and remove the contraflow as soon as the risk of disruption has passed.
However, should any disruption occur due to delays at the Port of Dover or Eurotunnel, we want to do all we can to support you through this by offering as much help and advice as possible.
For the latest updates on any services changes and useful contacts in your community, you can find out more by visiting the following websites:

Also, a reminder about access for emergency services during times of heavy traffic or disruption:
- FIRE - Kent Fire and Rescue Service has plans in place to make sure they can carry on providing an effective emergency response in areas of significant congestion. They do this by moving crews, fire engines and other resources around the county to provide cover where it’s needed. They urge everyone to only call 999 in an emergency, where there is a risk to life or property.
- AMBULANCE - In periods of expected increased traffic build up, South East Coast Ambulance (SECAmb) can station paramedics in your area to ensure they are as prepared as possible to provide care for seriously ill or injured patients. In periods of disruption in and around Dover and Folkestone, they may organise for ambulance crews to start and finish their shifts more locally, which would further help with the response. Please be assured that SECAmb position their vehicles to best respond to patient demand. You can help manage demand by only dialling 999 in an emergency and making use of alternatives including NHS 111.
- POLICE - Kent Police officers will still reach you quickly in an emergency even when there is heavy traffic congestion. They have enough officers in place to enable them to get to an emergency, and can move people around the county to provide cover where it is needed. You do not need to visit a police station to report an incident. The quickest way is online at https://www.kent.police.uk/ro/report/ but always call 999 in an emergency including if a crime is in progress or someone’s life is at risk.
- NHS - The NHS in Kent and Medway has tried and tested plans to make sure patients can access the care they need during periods of disruption. Patients can help by making sure they use the right service for them. If you are not sure where to go or what help you need, use NHS 111 online (111.nhs.uk) or on the phone.
After a successful trial in the summer, I am pleased to tell you that the freight permit scheme will once again be in place if Operation Brock goes to control, and lorries start to be filtered down to the port from the M20. No permit means no entry to the Port of Dover, which significantly reduces vehicles attempting to jump the queue, circumnavigate the restrictions, and cause problems on local roads.
Traffic levels will be monitored 24-hours a day, while Operation Brock is deployed, by a team made up of KMRF partners including Kent County Council and the emergency services, with traffic officers at points through Dover town.
While there may be some local traffic restrictions, we will continue to explore and test new ways to assist residents.
Our priority, as always, is to ensure everyone is able to get to where they want to go safely and as quickly as possible and to enjoy the Easter break.
