The New England Highway has reopened to traffic after an earlier two car collision.
Motorists are being allowed to pass in one direction at a time with alternating stop and go traffic conditions in place, after the earlier crash which injured three people.
Drivers are being urged to allow extra time for their journey.
A teenager and a woman were among three people rushed to Tamworth hospital following a two-car collision that shut the New England Highway near Moonbi.
