Crews spent much of Monday evening cleaning up parts of Interstate-35 after a semi hit a bridge.
Police say the truck was heading northbound when it hit an overpass at the Cumming exit and then crossed the median into oncoming traffic.
The driver was taken to a Des Moines hospital with minor injuries. No one else was hurt.
Northbound traffic was reduced to one lane. Traffic in the southbound lane had to be diverted while crews cleaned up the wreckage.
