A semi-truck hauling a trailer of cattle overturned on I-35 Tuesday morning causing a traffic backup.
It happened around 8:30 near mile marker 100, in the northbound lane between the Elkhart and Huxley exits. The truck went off the east edge of the road and tipped into a small ravine, smashing the cab of the truck.
The Iowa State Patrol says the driver was taken to a local hospital for treatment of his injuries and his condition is unknown.
Thirty-seven cows were in the trailer and officials say some of them died and some are injured. The surviving animals have been corralled and ISU veterinary medicine personnel is helping to assess, treat, and remove the cows.
The right lane of northbound I-35 will be closed in the area while officials deal with the situation.
A second accident was caused at mile marker 99 by the traffic slowdown in the area, but the Iowa State Patrol says injuries don’t appear to be life threatening.
