One person was seriously injured in a crash on Interstate 65 yesterday afternoon near Columbus that tied up traffic for hours.

Indiana State Police say that 50-year-old Wendy Crowder of Veedersburg, Ind. was seriously hurt when her SUV was struck by a semi driven by John G. Olson of South Milwaukee, Wis. near the Walesboro exit at about 1:30 p.m. Thursday. Police say they don’t know why, but Olson’s semi crossed the centerline into the southbound lanes of the highway striking Crowder’s vehicle before going back into the median.

Crowder was flown to IU Methodist Hospital in Indianapolis. Olson was uninjured.

Olson’s trailer contained a load of potatoes that shifted during the crash. Traffic was slowed in both directions for nearly six hours while crews worked to offload the potatoes before removing the vehicle from the median.

The investigation is ongoing.
