The Iowa State Patrol says a flatbed load of aluminum spilled onto Interstate 29 Thursday morning during an accident in Harrison County. A 2010 Peterbilt semi driven by 33-year old Tiras Prothro, of Chicago, IL, was traveling north on I-29 at around 5:25-a.m., when the rig veered to the left and went out of control. The semi entered the median and rolled onto its side. A load of aluminum being hauled by the rig was tossed onto the southbound lanes of I-29 when the accident occurred.

The trailer, which tipped over and came to rest across both northbound lanes on I-29, was hit broadside by a 1999 Peterbilt semi. No injuries were reported.
