Operation Brock is the name for a series of measures that improve Kent's resilience in the event of cross-channel disruption.
The deactivation reflects the decreased risk of disruption to services across the English Channel in coming days and weeks.
Tomorrow (Wednesday) morning there will be three lanes on the coastbound M20 operating at national speed limit and two narrow lanes Londonbound at 50mph. This means Operation Brock can be activated again quickly if it is needed in the coming months.
To make the changes the M20 will be closed to coastbound traffic between junctions 7 for Maidstone and 9 for Ashford from 8pm tonight until 6am tomorrow. A clearly signed diversion will direct traffic via the A249 and the M2.
