A truck driver has been rushed to hospital after her vehicle rolled over on the Princes Freeway, causing major road delays in Melbourne’s west. 

Fire Rescue Victoria said it took 45 minutes to rescue the 61-year-old woman, who was trapped.

Several tonnes of chipboard lay scattered over the freeway and the slope beside the wrecked truck.

A fire spokesperson said it would take several hours to clean up the debris from the roadway.

He said it was not the first time an incident like had happened on the same bend in the road.
