Two men accused of causing the closure of the Queen Elizabeth II Bridge at Dartford for two days in October are due to stand trial next year.
Marcus Decker, 33, of no fixed address, pleaded not guilty at Basildon Crown Court to one count of causing a public nuisance.
Morgan Trowland, 39, of Drummond Way, Islington, north London, did not attend the hearing, but the court was told he had indicated a not guilty plea to the same charge.
The trial is scheduled for Basildon Crown Court on 27 March.
The bridge was closed to traffic during the incident and all drivers were diverted via the Dartford Tunnel.
