A semi trailer rollover on the roundabout adjacent to the Narrabri Shire Council depot on Friday morning caused Newell and Kamilaroi highway traffic to be diverted for several hours.
Emergency services attended the scene and a heavy vehicle tow truck was called in from Moree to right the trailer loaded with hay.
Narrabri Fire and Rescue cleared a diesel spill resulting from the incident.
There were no injuries, Narrabri police said.
The site of the rollover at the roundabout has been the scene of several similar accidents in recent years.
