A triple-decker stock truck from Young has overturned on the Wombat Road near the entrance to Shea’s Pit, on the northern approach to the Demondrille Railway Bridge.
The driver did not suffer any major injuries.
Up to 30 sheep were either killed in the accident or subsequently destroyed so far, and operations are currently underway to recover the remaining stock.
Harden Shire Council workers are directing traffic.
More updates to follow.
