Operation Stack is the name used by Kent Police and the Port of Dover in England to refer to the method of using sections of the M20 motorway in Kent to park lorries when the Channel Tunnel, English Channel or Dover ports are blocked by bad weather or industrial action, or enforced closure due to fire or derailments in the case of the tunnel. The system has been implemented over 75 times since its inception 20 years ago.
