The crash happened shortly after 1pm, about one kilometre south of the service station.

NSW Police have confirmed a 74-year-old woman was killed after her Holden Barina and the B-double truck collided.

The woman died at the scene. A report will be prepared for the coroner.

The male truck driver was not injured in the crash but sent to hospital for mandatory blood and urine testing.

Southbound traffic has since reopened and heavy traffic eased.
