Jefferson Avenue (Detroit) in the context of "M-1 (Michigan highway)"

M-10 is a state trunkline highway in the Metro Detroit area of Michigan in the United States. Nominally labeled north-south, the route follows a northwest-southeast alignment. The southernmost portion follows Jefferson Avenue in downtown Detroit, and the southern terminus is at the intersection of Jefferson and M-3 (Randolph Street) next to the entrance to the Detroit–Windsor Tunnel. The northern terminus is in West Bloomfield Township at the intersection with Orchard Lake Road. The highway has several names as it runs through residential and commercial areas of the west side of Detroit and into the suburb of Southfield. It is called the John C. Lodge Freeway (The Lodge), James Couzens Highway, and Northwestern Highway. One segment has also been named the Aretha Franklin Memorial Highway.

M-10 was built in segments through the late 1950s and early 1960s. It carried several different names before the entire route was finally officially named the John C. Lodge Freeway in 1987. The freeway has carried a few other highway designations. The southern segment was part of US Highway 12 (US 12) and the whole road was later renumbered Business Spur Interstate 696 (BS I-696). From 1970 until 1986, it was part of US 10, and the freeway has been M-10 since. The non-freeway segment that runs between I-696 in Southfield and Orchard Lake Road was previously numbered M-4. M-10 was named after John C. Lodge, an influential Detroiter and Mayor of Detroit from 1927–28.

Interstate 375 (I-375) is a north–south auxiliary Interstate Highway in Detroit, Michigan, United States. It is the southernmost leg of the Walter P. Chrysler Freeway and a spur of I-75 into Downtown Detroit, ending at the unsigned Business Spur I-375 (BS I-375), better known as Jefferson Avenue. The freeway opened on June 12, 1964. At only 1.062 miles (1.709 km) in length, it once had the distinction of being the shortest signed Interstate Highway in the country before I-110 in El Paso, Texas, was signed. The Michigan Department of Transportation (MDOT) announced in 2021 plans to convert the freeway to a boulevard. Details of that project were revealed in April 2023 with MDOT reaffirming that construction is scheduled to begin in 2025.
