The Iowa DOT reports (as of 7:15-a.m.), Interstate 80 westbound in Cass County is blocked between Exit 57 (the Olive Street exit), and Exit 54 (Highway 173/Elk Horn), due to an accident. A KJAN listener reports a semi has tipped over onto its side, blocking both lanes. The crash is just beyond the Olive Street overpass. Westbound traffic was being rerouted off I-80 westbound at the Exit 57 ramp, across Olive Street and back down the I-80 westbound on-ramp, around the obstruction.
