Here is everything that you need to know about Operation Brock.
Operation Brock is the traffic management scheme to safely direct Heavy Goods Vehicles (HGVs) to both the Channel Tunnel (Folkestone) or the Port of Dover in the event there are severe delays in cross-channel travel.
Operation Brock has been implemented to avoid the need to close the M20 and get drivers and their cargo to their destination in the safest and quickest method possible. Delays are expected to be around 36 hours, therefore the restrictions are put into place in order to avoid thousands of vehicles being stranded indefinitely. Ultimately leaving the motorway and surrounding areas in a state of gridlock.
Highways England devised the final plan for Brock earlier this year and have devised the structure into four phases, depending on the level of congestion.
Phase 4 is implemented when there is no remaining space for HGVs queuing for the Channel Tunnel. The M26 will be closed entirely and HGVs are parked on the carriageway until space becomes available on the M20.
