No injuries were reported after a semi rolled over on Interstate 80 Thursday night in Pottawattamie County. The Iowa State Patrol says a 2012 Peterbilt tractor trailer driven by 41-year old Frank Scott Hofreiter, of Santee, CA, was traveling west on I-80 near the Underwood exit, when for reasons unknown, the rig went out of control and entered the median, before rolling onto its side and spilling its load. The wreckage partially blocked the westbound left lane of the Interstate when the crash occurred, at around 9:40-p.m. The Patrol says it was rainy and windy at the time of the accident, but it’s not clear if that played a role in the crash.
