A MAN has died following a collision between a truck and a utility on the Great western Highway at Mount Lambie.
The head-on collision occurred at approximately 5.20am on Friday.
Chifley Police District duty officer Inspector Gerard Powell said that the utility was travelling west at the time of the accident and was being driven by a male, believed to be 35 years of age.
"[The utility] collided head-on with a prime mover semi trailer. The vehicle burst into flames," he said.
"Unfortunately an assumed 35-year-old male was found deceased inside."
Inspector Powell said the driver had yet to be identified as of Friday afternoon.
Paramedics from NSW Ambulance assessed the driver of the truck, a 51-year-old male, before taking him to hospital.
"The truck driver was taken to Lithgow Base Hospital for treatment for shock and mandatory testing," Inspector Powell said.
MAP: Where the collision occurred ...
The highway was closed in both directions upon the arrival of emergency services and traffic was diverted via Range Road, Pipers Flat Road, Wallerawang and Barton Avenue until motorists could rejoin the Great Western Highway.
Emergency services were joined at the scene by Roads and Maritime Services and heavy vehicle inspectors.
It took several hours for the scene to be cleared, with the highway officially re-opening at around 2pm.
Speed limits of 40 kilometres per hour were put in place on the highway in the early afternoon as the road became clear.
Motorists taking diversions around mid-morning faced further delays due to an incident on Pipers Flat Road.
Police will continue to investigate the circumstances that led to the crash at Mount Lambie.
