A CALTEX fuel tanker that crashed and rolled over at the roundabout at the Gladstone-Benaraby turnoff yesterday afternoon spilt 10,000 litres of diesel into nearby drains and blocked access to Boyne Island and Tannum Sands well into the night.
Police believe the tanker was carrying between 30,000 and 40,000 litres of diesel.
Emergency services were called to the roll over at 3.20pm as it was reported the male truck driver had lost consciousness in the accident.
As The Observer went to print a spokesman for Queensland Ambulance did not have any further information on the truck driver's injuries but said the he had been taken to Gladstone Base Hospital about 4.40pm.
A different truck driver, from Brisbane, who pulled up to the area shortly after the accident, did not want to be named but said he could smell the heavy fumes of diesel.
The truck driver did not want to speculate on the cause of the crash but thought speed may have been a factor because none of the truck's tyres had blown.
There were heavy delays along Gladstone-Beneraby Rd well into the night as police diverted traffic away from the area.
Police were stopping traffic at both Kirkwood Rd and at Benaraby which meant motorists had to travel along the Bruce Hwy and out to the crossroads at Calliope to get into Gladstone and to Tannum Sands Rd to get access to Boyne Island and Tannum Sands.
Four police crews were on scene as well as ambulance, fire services, Ergon energy and a representative from the environmental protection agency.
Dirt and sand was last night put down on the road to help clean up and prevent the diesel from spreading further.
Two cranes had been sent to lift the fuel tanker back onto its axels.
In a separate incident earlier yesterday morning, a truck carrying food supplies bound for Tannum Sands rolled his vehicle after he is thought to have "lost concentration" while driving along Tannum Sands Rd (inset picture, left). Police Sergeant John Meiers said the 42-year-old truck driver "lost control" of the vehicle.
"He's driven off the side of the road and lost control of his vehicle," Sgt Meiers said. "Subsequently the vehicle has overturned."
The man was a truck driver for Rum City Foods, a Bundaberg food product delivery company.
