Public input requested for proposed improvements on Iowa 175 at Interstate 29 near Onawa in Monona County

The first improvement includes a bridge replacement on Iowa 175 over Interstate 29 as well as reconstruction of the interchange ramps. This project also includes the reconstruction of the 28th Street / Filbert Avenue / Iowa 175 intersection with left turn lanes on Iowa 175.
