156:. Both directions of motorway traffic are directed onto the westbound carriageway contraflow at a speed limit of 50 mph. The eastbound carriageway will then be closed and used for HGV queuing in two lanes (the hard shoulder and 3rd lane) with the other two lanes reserved for emergency vehicles, maintenance vehicles and amenities. This would be marked out with cones and subjected to a 30 mph speed limit. Due to the contraflow setup, non-HGV traffic cannot join the M20 eastbound at Junction 8.

The road will be reduced to 40 mph and all other traffic will use the right hand lane.

The contraflow has been the height of issues however. As
Operation Brock was not used due to Brexit being delayed, the decision was made to partially revert the M20 back to its original state. This was done by reopening the eastbound carriageway fully, and keeping the steel barrier in the event that

In
January 2019, a rehearsal for part of Operation Brock was carried out, using the former Manston Airport as a lorry park. It was criticised for being unrepresentative of the actual situation that would occur in reality. On the first day of the test, only 89 of the planned 150 lorries turned up for
