National Highways has said it will relocate the movable barrier on the M20 used as part of Operation Brock later this month.
National Highways will be carrying out an extensive drainage upgrade, ground work to enable storage of the movable barrier and signage installation in the central reservation and London-bound verge to move the Brock barrier, which forms part of the Brock contraflow system, between junctions 8 (Maidstone) and 9 (Ashford) of the M20. Work is due to start overnight on Friday 28 January, and will last up to 12 months.
The barrier, which can be installed on the motorway as part of measures to keep traffic moving on M20 if there is disruption in the county, is currently being stored on the London-bound hard shoulder but will be relocated to the central reservation.
The current arrangement, which was deployed in December 2020, uses the moveable barrier to allow the Brock contraflow system to be activated on the M20 London-bound carriageway, should the coastbound carriageway be required for queuing port-bound freight. This keeps the M20 open for use rather than traffic diverting
The work to move the barrier will take place in phases, and to carry it out safely, lane closures and a small number of overnight closures will be needed. These will be notified in advance.
Between January and October 2022, the moveable barrier will be used as a traffic management barrier on the London-bound carriageway, while this work takes place. This does not mean the Brock contraflow system will be active, but it will provide a more efficient and cost-effective way of being able to deploy the contraflow quickly and effectively should it be required.
