M-54 (Michigan highway)

State highway in Genesee and Saginaw counties in Michigan, United States
Past the town, M 54 turns due north on Clio Road before crossing into southern Saginaw County. Over the county line, the name changes to Gera Road, and the trunkline runs through farm fields to an intersection with Birch Run Road. At that intersection, M 54 northbound turns westward and joins M 83 to run concurrently to Birch Run while M 83 continues north to Frankenmuth on Gera Road. Birch Run Road carries opposing directions of the two highways, a phenomenon called a wrong way concurrency. Running westward, the road is signed as both M 54 northbound or M 83 southbound. About 2 mile (3 km) west of the intersection between Gera and Birch Run roads, the two highways meet a common terminus at exit 136 on I 75/US 23 in a commercial district that includes a large outlet mall bordering that freeway. M 54 between I 75 in Grand Blanc Township and M 57 near Clio has been listed on the National Highway System, a network of roads important to the country's economy, defense, and mobility.

The first version of M 54 began at M 16 (later US 16) near Grand Rapids and ran northerly along the current M 37 corridor to M 20 (later US 10). This version of M 54 was replaced by an extension of M 37 by 1927. The second incarnation of M 54 was designated in Ironwood along the former US 2 routing through downtown in 1934. This was replaced by the current Bus. US 2 in August 1942.

Originally, Saginaw Road in the Flint area was a part of the Saginaw Trail, a Native American footpath in the area. When the state signed its highway system in 1919, In August 1926, the Flint City Council renamed the former Western Road after Josiah Dallas Dort, a partner in GM. In 1941, the highway was moved eastward to follow Dort Highway, and the route through the city was designated Bus. US 10. An extension of Dort Highway in 1987 relocated the southern end of M 54 in Grand Blanc to end at exit 109 on I 75.
