A collision following a semi rollover resulted in one vehicle on fire and clogged traffic on I-380 at US-20 in Black Hawk County.
The Iowa State Patrol said it happened about 9:30 Wednesday morning when a northbound semi truck went off the road on the ramp to westbound US-20 and rolled on to its side. A van driver then stopped to help the semi driver. Troopers said a second semi then hit the van and crashed under the overpass, catching fire. Troopers said northbound I-380 to westbound US-20 traffic was diverted for more than 6 hours.
