The two police forces on either side of the Thames estuary are teaming up to work more closely on operations.
The forces will collaborate on policing the Dartford crossing
Kent and Essex police said there were no plans to merge the forces but described Operation Forefront as a ground-breaking collaboration project.
Home Office funds have been allocated to both forces and police authorities to drive the programme forward, a spokeswoman for Kent Police said.
Kent Police has been given £500,000 towards the work.
Under the partnership, the forces plan to team up on policing the Dartford crossing, as well as ports and airports on both sides of the River Thames.
Kent Police also told BBC Radio Kent that the force would be able to use the Essex police helicopter.
The scheme will also see the two forces sharing resources and equipment, to make more money available for frontline policing.
Chief Constables Roger Baker and Michael Fuller will talk about the partnership, and its aims and achievements.
A joint collaborative committee has been set up to oversee the work.
