The Princes Hwy between Yarragon and Trafalgar has re-opened after a truck rollover this morning.

The east bound lanes re-opened after being closed for six hours.

A 54-year-old truck driver from Dandenong was airlifted to Melbourne with non-life threatening injuries.

Police said it appeared the truck collided with the back of another truck, lost control and veered into the centre median where it rolled, losing its load of dirt and gravel.

Heavy haulage was brought in to clear the scene.
