A 53-year-old man and a 26-year-old man have died in separate road accidents in Queensland.

Two men have died in two separate road accidents in Queensland.

A 53-year-old man from Westbrook died in a single vehicle crash near Millmerran, in the Darling Downs, about 11.30am (AEST) on Wednesday when his car rolled while driving on Cypress Avenue.

Another man died after a ute and a truck collided on the Bruce Highway south of Tannum Sands, on the central east coast about 5.30pm.

The 26-year-old Booval man, the single occupant of the ute, was pronounced dead at the scene, while the truck driver was transported to hospital for observation.

The highway was closed in both directions for several hours.

The Forensic Crash Unit continues to investigate both accidents.
