A southbound truck crashed off the Hume highway about 6.30am on Tuesday morning.
A Hume LAC NSW police spokesman said no injuries were reported, although the truck was badly damaged.
The spokesman said the truck is completely off the road and so is not affecting traffic.
He said one lane will need to be closed at a later time to tow the truck.
The crash happened about two kilometres past the Federal Highway/Hume Highway fork.
