A crash involving two semis caused traffic headaches on I-80 in between the Adair and Casey exits early Thursday morning. The Iowa State Patrol says a westbound semi lost a tire at mile marker 80, just shy of the I-80 rest stop, then crashed into a semi that was parked at the rest stop. Both vehicles caught fire. The whole interstate ended up having to be shut down because the water used to fight the fire froze, icing over the lanes of travel. As of 8:30 a.m. only the right lane of westbound I-80 remained blocked off while crews work to remove the burned semis. The ISP says only minor injuries were reported in the crash.
