CASEYVILLE, Ill. (KMOV-TV) -- Three cows were on the loose early Monday after an overturned semi hauling the animals flipped onto its side on Interstate 64.
The tractor-trailer accident happened about 1:30 a.m. in the westbound lanes of Interstate 64 near the Interstate 255 exit in Caseyville.
An Illinois State Police officer on the scene said the driver was taken away by ambulance but appeared to be okay.
Police say the driver told them his rig lurched to the right, hit the concrete median wall and then flipped onto its side.
Three of the cattle on the truck got out of the trailer after the accident. Workers used a cattle prod to move the cattle from one trailer to the other. While transferring the cattle, one cow was able to break loose and run across the interstate. That cow was later chased off the highway and shot.
The Caseyville Fire Chief says the cattle, which weigh between 1,500 and 2,000 pounds, could have done some serious damage if struck by a car moving in excess of 60 mph.
The bottleneck conditions at the scene led to a traffic slowdown and back-up for commuters.
Authorities report that the semi was transporting 65 cattle.
