POOR visibility and a slippery road surface are thought to have contributed to a low-speed truck rollover crash near Gympie's southern Bruce Hwy exit yesterday.
Police and emergency crews said it appeared the truck driver had attempted to pull over to the side of the road, at Alford Park duck ponds, opposite 4GY.
No one appeared to have been hurt in the incident, but several boxes, believed to be mandarins, were damaged when they fell out of the ruptured side of the truck.
Tow truck operator Claytons Towing quickly had a large crew of workers on site cleaning up the area.
The truck was on its way to the Brisbane Markets late on Wednesday night, taking a load of fruit and vegetables from Bowen.
The produce, from Olde McDonnell's Farm, was only partially recovered, it appeared yesterday.
About eight Claytons employees attempted to right the truck, using air bags to lift it so that other equipment could be attached.
But the fully laden trailer was too heavy and its insulated sides cracked under the weight of the boxed produce.
Working in freezing and damp conditions, the Claytons crew then opened up the refrigerated trailer and removed the fruit and vegetables, possibly for salvage.
The crash occurred about 11pm, but workers were still on-site early yesterday morning and eventually transferred the load to another vehicle.
Hundreds of undamaged boxes of produce are believed to have been salvageable, but some had to be dumped.
Police said the sloping roadside appeared to have been steeper than the driver estimated and it was possible the driver could not see well enough in the foggy conditions to continue on his journey.
The highway remained open throughout the incident, one witness said.
