As part of the US Highway 20 / Swiss Valley Interchange project currently under construction, the Iowa Department of Transportation will be closing a segment of North Cascade Road between Royal Wood Drive and Swiss Valley Road beginning on Monday May 10th. There will be no post detour. Local access to properties along the road closure segment will be maintained.

The segment of North Cascade Road between Royal Wood Drive and Swiss Valley Road will remain closed until the new relocated North Cascade Road construction is completed and the new intersection with Swiss Valley Road is completed.
