Ames, IA (KICD)– The Iowa Department of Transportation is taking public comment on a proposed roundabout in Cherokee County.

The suggested change would be at the intersection of Highways 3 and 143 near Marcus.

Traffic on Highway 3 would be maintained by staging construction for most of the project that is expected to begin in Spring 2026 and end later that fall, but a detour is expected for the final stage.

Anyone wishing to voice their opinion on the matter can do so on the Iowa DOT website through Friday, April 19th.
