A CAR crash has caused extensive delays on the Pacific Highway at Twelve Mile Creek.
The Transport Management Centre was advising motorists heading in a south-bound direction to allow extra travel time.
It came after a car rolled shortly after 1pm.
There were diversions in place, but the road reopened about 4.30pm.
Paramedics said three females – including a young girl – were taken to John Hunter Hospital with minor injuries.
They were in a stable condition, a spokeswoman for Hunter New England Health confirmed.
