Operation Stack is a procedure that uses parts of the M20 to queue lorries travelling towards the continent, to avoid causing gridlock across Kent's roads.
It is used in emergency situations when crossings to the continent cannot happen, such as bad weather or industrial action.
Kent Police are responsible for implementing Operation Stack.
Check the roads before you travel
Avoid travelling along the M20 during Operation Stack if possible.

The use of Manston Airfield as a temporary option to help hold lorries as part of Operation Stack – a multi-agency response to deal with the transport disruption – was announced by the Government recently.

Future alternatives to Operation Stack
Our response to the Highways England consultation proposal of two possible site locations for operation stack was debated at the Environment and Transport Cabinet Committee on 13 January 2016. Read our statement in response to the consultation.
Dover TAP (Traffic Assessment Project)
Dover TAP is a separate scheme to Operation Stack. It is used to manage traffic using the Port of Dover and to improve air quality and reduce congestion in the town. Dover TAP is managed by Highways England.
