Historical Road Conditions

Select Road Segment: Select Year Select Month

The Iowa Environmental Mesonet archives the road condition reports as generated by the Iowa State Patrol. From this page, you can generate a listing of road conditions per road segment for a particular month or a listing of all road conditions for a particular time. Currently, our archive is basically complete back to 14 Feb 2006.
