Other Routes

While the original intent and still a major focus of the Michigan Highways website was to catalog the various numbered Interstate, US and State-designated highways, there are other types of marked routes in Michigan. Some of the "other" routes are posted along the state trunklines, while others have nothing to do with the state-maintained system of highways. Because of this, the signing of some of these "other" types of highways may be less than thorough and detailed maps may need to be consulted in order to follow them.
