Reports Operation Stack has cost Kent Police more than £123,000 in overtime payments this year have led to renewed calls for Highways Agency action.
Operation Stack has been brought in regularly during 2005
Kent Transport Board wants a lorry park to be built so trucks do not have to wait on the M20 during port delays.
Councillor Graham Gibbens, chairman of the board, said: "We need Highways Agency initiatives on plans to manage lorries on their road."
The agency has said it is looking for a solution but has no proposals yet.
The overtime costs figures were obtained by local media under the Freedom of Information Act.
Mr Gibbens told BBC Radio Kent said numbers of coast-bound lorries travelling through Kent had increased by a million in 1994, three million in 2004, and forecasts four million by 2014.
Last month, proposals to use the county showground at Detling as a lorry park met with opposition from the parish council, but the Highways Agency said it was just one of several ideas.
In a statement it said: "The Highways Agency is working with a number of agencies to help find a long-term solution to Operation Stack.
"Using land to park lorries off the highway is just one of a range of ideas that have been put forward.
"These will need to be discussed in more detail and it is too early to say at this stage what might emerge as a solid proposal."
The transport board wants to see the lorry park located close to the Channel ports.
