THE Western Highway will be shut for part of Wednesday near Kaniva after two trucks ploughed into a flock of sheep on Tuesday night.
Horsham police Sergeant Jason Bergen said more than 70 sheep died.
He said the trucks were travelling east on the Western Highway at Lillimur at 8.50pm when they smashed into the flock, which had escaped from a nearby property and wandered onto the road.
"The first truck jackknifed on the road, and the second had extensive damage to the front," he said.
The drivers were uninjured.
Sgt Bergen said leaking fuel mingled with the sheep carcases, smeared along the road's surface.
He said the Western Highway was closed for a period of time.
Sgt Bergan said heavy haulage attended, but were unable to remove the trucks.
He said the trucks were left on the side of the Western Highway, pending heavy haulage's return.
"The highway will be closed again for short period of time while they recover the trucks," he said.
Sgt Bergen said another truck sped through the scene at 2.20am, while emergency services and council workers were working to clear the road.
"Another B-double truck drove through clearly displayed 80km and 40km signs and collided with a council vehicle," he said.
The council car was doing traffic control.
Sgt Bergen said the driver was uninjured, although their vehicle sustained some damage.
"The driver was issued a penalty notice for careless driving," he said.
He said the driver put their own safety and the safety of all those still clearing the road in danger by failing to slow down.
"It's a good reminder for people - if they see flashing light or signs telling them to do 80 or 40 kilometres an hour, they're there for a reason," he said.
