M20 BREXIT: Motorists face delays and disruption for M-way testing - details

Thursday 3rd December 2020

M20 users are to face delays, diversions and disruption next week as the country prepares for the next phase of Britain's departure from the European Union.

Highways England and the Kent Resilience Forum are carrying out a live test to "mobilise" a moveable barrier system on a section of the M20 from Friday, December 11.

Part of the M20 will be closed between Maidstone and Ashford for four nights, with signed diversions in place.

The barrier, part of Operation Brock, is part of a contraflow system designed to keep traffic travelling in both directions while port-bound lorries are held on the coastbound carriageway.

Highways England claims the Brock is easier to install but critic say it is too fragile and prone to accidents which would grind the system to a halt.

Highways England south east operations director Nicola Bell said: "We have again worked extensively with our partners in Kent and are confident that this test will provide a valuable dress rehearsal into the operation of our Kent-wide port disruption contingency measures.

"The test will help us to fine tune Operation Brock, finding ways to make the deployment quicker whenever the barrier is needed, whether it be in preparation for transition, or other disruption to cross-channel services.

"Operation Brock will keep Kent moving, and we thank road users in advance for their patience while the test is taking place."

Transport Secretary Grant Shapps said: "Kent is a critical link to one of our busiest trade routes, and this state-of-the-art technology will ensure that we can keep the local road network moving."

WHAT IT MEANS FOR KENT

According to Highways England:

To make sure the barrier is deployed and removed safely, the M20 will be closed coastbound between junction 7 (for Maidstone) and junction 9 (Ashford), and London-bound between junctions 9 and 8 (Maidstone East), overnight (8pm to 8am) on Friday 11, Saturday 12, Sunday 13, and Monday 14 December, returning to normal operation by 8am on Tuesday 15 December. Whenever the M20 is closed, signed diversions will be in place.

At the end of the test the barrier will be returned to the London-bound hard shoulder.

What will the M20 look like during the trial?

The M20 will close in both directions overnight between junctions 7 and 9 (coastbound) and junctions 9 and 8 (London-bound) on Friday 11 December for the installation of the moveable barrier.
When the M20 reopens by 8am on Saturday 12 December, the contraflow will be in place in its initial phase. Drivers will need to follow the different layout on the M20 from just north of Junction 8 (for Hollingbourne/Leeds) to Junction 9 (Ashford). Lorries heading for mainland Europe will be routed down the coastbound carriageway, with a 30mph speed limit in place. All other traffic will be directed onto the contraflow, with two lanes in each direction operating at 50mph.
The M20 will close in both directions overnight between junctions 7 and 9 (coastbound) and junctions 9 and 8 (London-bound) at 8pm on Saturday 12 December and reopen by 8am on Sunday 13 December with the contraflow now open in its final phase.
The M20 will again close overnight between junctions 7 and 9 (coastbound) and junctions 9 and 8 (London-bound) at 8pm on Sunday 13 December for removal of traffic management on the coastbound carriageway.
When the M20 reopens by 8am on Monday 14 December, the coastbound carriageway will be back to normal, with all traffic management removed. The London-bound carriageway will be open but some traffic management – including the moveable barrier – will still be in place. Speed restrictions will apply. The London-bound carriageway will be closed overnight between junctions 9 and 8 at 8pm on Monday 14 December with the moveable barrier being moved to the far side of the hard shoulder.
The London-bound M20 will reopen by 8am on Tuesday 15 December, with the M20 back to its normal layout in both directions, with three lanes operating at the national speed limit.

ABOUT OPERATION BROCK

Operation Brock is a series of measures which crucially keeps the M20 open in both directions using a contraflow system. As with previous deployments in 2019, Operation Brock has stages that can be deployed sequentially, scaling up or down to meet demand.

When Operation Brock is in force it is a legal requirement to use the signed routes only for HGV journeys to Port of Dover and Eurotunnel.

Depending on the scale of disruption, and whether HGVs are travelling to Port of Dover or Eurotunnel, they will be directed to a holding site.

Failure to comply with instructions may result in fines and further delays.

Kent Police take decisions on when to use the different phases of the system.

Options include:

A20 Dover TAP: A queuing system which holds lorries until space becomes available at the Port.
M20 Moveable Barrier: A concrete barrier than can be deployed quickly between junctions 8 and 9 of the M20 to install a contraflow. HGVs bound for Dover and/or Eurotunnel will be held on the coastbound carriageway.
Manston Airfield: an off-road site designed to hold traffic heading for the Port of Dover. Border readiness checks will take place here to ensure hauliers have the correct paperwork.
Ashford Sevington Inland Border Facility: an off-road site next to junction 10A of the M20, likely to be used if the M20 contraflow approaches capacity.
