Sheriff’s officials in Audubon County today (Tuesday) released details about a tractor-trailer rollover accident that took place Monday afternoon, northeast of Exira. Authorities say the driver of the semi, 32-year old Shawn David Irvine, of Clearmont, MO., was transported by private vehicle to the Cass County Memorial Hospital in Atlantic, following the accident that took place at around 3:30-p.m. on Pheasant Avenue, near 280th Street, or about three-miles northeast of Exira.

The Sheriff’s Dept. says Irvine was traveling south over the posted speed limit in a 2013 Peterbilt tractor-trailer registered to Sioux Valley Transport, L-L-C, of Estherville, when he entered a curve in the road. A load of market hogs shifted in the trailer, causing the semi to roll over onto the shoulder of the road. About 60 hogs died in the crash.

The semi sustained an estimated $100,000 damage. Irvine was charged with Failure to Maintain Control. The Iowa State Patrol and Exira Fire and Rescue assisted at the accident scene.
