A man has died after the B-double he was driving collided with a semi-trailer south of Port Macquarie this morning.
Both were travelling southbound on the Pacific Highway at Herons Creek at about 6:45, when the B-double hit the back of the semi.
Ambulance officers found the male driver of the B-double trapped in the cabin suffering from chest and leg injuries.
He died at the scene.
Both southbound lanes remain closed.
