Disruption was first reported on Friday (31 March) after operators P&O Ferries and DFDS blamed bad weather for the delays.
A "critical incident" was declared with coach operators being particularly hard hit, the BBC reported, with some companies turning around and returning home due to the delays.
The situation was "all clear" from 12.30am on Monday (3 April), a port spokesperson confirmed, after a buffer zone within the port had been emptied of coaches.
The port said: "The Port of Dover continued working round the clock with the ferry operators and border agencies to get coach passengers on their way and the backlog is now cleared.
