UPDATE: Road re-opened after highway truck rollover

UPDATE 1.45 PM: TRAFFIC is now slowly moving along the Carnarvon Highway 10km north of Roma, more than four hours after a serious truck rollover accident. 

A Queensland Police Service spokeswoman said police and fire teams remained on scene, with the road expected to be reopened to two lanes within the next half hour. 

"The road has been half opened at this stage, and traffic is getting through quite slowly," she said. 

The truck, which is believed to have skidded across the highway  before it flipped, is currently in the process of being removed, with a tow truck on site. 

As a result of the crash, molasses was spit across the road, with the majority of it contained to the road shoulder, and is not causing any traffic hazards. 

The female driver and her two children were transported to Roma Hospital. 

Police are investigating the incident.

EARLIER: A WOMAN and two children have been injured in a serious truck rollover 10km north of Roma on the Carnarvon Highway.

The incident occurred at 9.50am with police, paramedics and fire fighters attending the scene.

A witness told the Western Star the truck had veered off the road down a down and skidded across and flipped over.

A Queensland Ambulance Services spokesman said the female driver was being attended on the scene for lower leg injuries and abdominal pain.

The two children are also being assessed, one with an arm injury and the other without obvious injuries, both are believed to be in a stable condition.

Traffic is backed up in both directions on the Carnarvon Highway, with an estimated one hour before the road is cleared.

It is understood the truck was transporting molasses, which has now spilled across the highway.
