Four bridges used by the highway have been recognized for their historic character as well.
There have been seven business routes of US Highway 31 in the state of Michigan. All of the business routes are former sections of US Highway 31 (US 31). They connect the freeway mainline of US 31 to the various downtowns of cities bypassed by US 31. Two of the current business routes, for Hart and Ludington, are business spurs, connecting to US 31 on only one end, while the remainder for Muskegon, Whitehall–Montague and Pentwater, are business loops. The two former routes, for Niles and Holland were a business spur and loop, respectively.
There have been five different business routes of US Highway 23 in the state of Michigan. These business routes were designated along former sections of US Highway 23 (US 23) to provide signed access from the main highway to the downtowns of cities bypassed by new routings of US 23. Two are still extant, connecting through downtown Ann Arbor and Rogers City. Three others have been decommissioned. The former Business US 23 in Fenton was split in half during the 1970s and later completely turned back to local control in 2006. The former business loops through Saginaw and Bay City were renumbered as business loops of Interstate 75 in the 1960s.
