(KSDK) - A crash involving dozens of horses shut down part Interstate 44 in Franklin County Wednesday morning.
Investigators say the driver of an eastbound tractor-trailer veered off the road and into the median. The semi overturned about 3:30 a.m. near Sullivan. The accident caused traffic to be backed up for miles.
The horses were being taken to Cavel, a slaughter house in DeKalb, Ill.
A woman riding in the truck went to the hospital with minor injuries. The driver was taken into police custody on outstanding warrants.
An animal response team is helping get injured horses out. Fourty-two horses were in the trailer. Sixteen horses were killed in the accident or were euthanized at the scene.
Workers built a temporary holding pen on the highway, then loaded the animals onto trailers.
The 26 survivors were taken to the St. Clair Saddle Club for treatment before being moved to animal hospitals, or foster homes.
The Missouri State Highway Patrol has asked the Humane Society of Missouri and its Longmeadow Rescue Ranch to care for the surviving horses until a permanent determination can be made. The Humane Society is seeking custody of the horses.
I-44 reopened to traffic around 11 a.m.
