There are three business routes of US Highway 10 (US 10) in the state of Michigan. They serve as connections from the main highway into Reed City, Clare, and Midland. Additionally, there were another two business routes that connected US 10 to the downtowns of Flint and Pontiac. All these business routes are, or were, former sections of US 10 that were marked Business US Highway 10 (Bus. US 10) after the main highway was realigned to bypass the downtowns of the cities.
The Reed City Bus. US 10 was created by 1960 to follow Chestnut and Church streets into the community's central business district and through adjacent residential areas. In 1975 when US 10 was rerouted to follow the freeways around Clare, the former routing through downtown on McEwan and Fifth streets was redesignated as a business loop; it was also signed to provide connections between US 10 and what is now US 127 because of an incomplete interchange between those two freeways. The Midland business loop dates back to 1961 and follows Eastman Avenue and two sets of one-way streets before completing its routing as a freeway. The two business loops created for Flint and Pontiac were designated in 1941 and 1961, respectively. They followed streets that were once part of US 10, but, after additional changes to US 10's routing in Michigan, they were renumbered as business loops of other highways in 1962 and 1986, respectively. Near Flint, part of US 10 was replaced by M-54 when the US Highway was moved to a freeway, and, near Pontiac, it was replaced by US 24 after US 10 was truncated in the state.
