Iowa DOT News Release

Interstate 35 and other roads blocked in due to overturned vehicles and storm damage

Posted on: August 10, 2020

AMES, Iowa -  Aug. 10, 2020 – The Iowa Department of Transportation is reporting several Iowa roads are impassible this afternoon, including Interstate 35 in both directions between Ames and Alleman and I-680 between Cedar Rapids and Iowa City due to the severe weather.

Storm damage has impacted communications to digital message boards, so incoming traffic may not be alerted to the closures as they normally would be. There is currently no detour identified for the interstate closures as several of the usual detour routes are also impacted by the storm with debris and power lines over the roadway.

The Iowa DOT recommends limiting travel in impacted areas as much as possible until crews can get out to remove power lines and clear debris.

Please note that communications and power issues are also limiting our ability to add information about all closures on We will update this site with as much information as possible.
