Thirty-five-year-old Callie Rose Lisa Derfinlinger, of Johnston, died following the crash that occurred a little after 11 a.m. on Interstate 80 near Shelby in Pottawattamie County.
The Iowa State Patrol says a pickup driven by Derfinlinger struck the rear of a semi driven by 56-year-old Stanley Dean Rottinghaus of Waterloo. The crash happened as both westbound vehicles were entering a 55 MPH construction zone.
The interstate was blocked and traffic was rerouted for about three hours, while the scene was investigated and vehicles were being removed.
