M-47 is a north–south state trunkline highway in the US state of Michigan. It runs near Saginaw and Midland in the Tri-Cities area of the Lower Peninsula. The highway runs through suburban and agricultural areas to connect the two cities with the airport in the area. The northernmost section of M-47 runs along a freeway to the terminus at US Highway 10 (US 10). M-47 runs for 14.328 miles (23.059 km), all of which has been listed as a part of the National Highway System.
First designated by July 1, 1919, along a different routing, M-47 was extended several times in both directions through the 1920s and 1930s. Two of these extensions replaced sections of M-111 in the Bay City area. At the apex of its length in the 1950s, M-47 stretched from Webberville in the south to Bay City State Park in the north. Since Interstate 75 (I-75) opened in the Tri-Cities area, the northern section of M-47 was rerouted and truncated as a result of related changes to other highways. The southern end was moved after I-96 opened in the Lansing area. Further changes into the 1970s shortened M-47 more, producing the routing in use today.
