The service drives change names again to Northwestern Highway upon crossing into Oakland County. The east side of M-10 is flanked by the Northland Shopping Center and a campus of Oakland Community College; the west side is residential. About into Southfield, M-10 intersects the northern end of M-39 (Southfield Freeway) and 9 Mile Road. The adjacent properties are mostly residential, but there are some commercial areas centered around the various Mile Roads, such as the campus of Lawrence Technological University at 10 Mile Road. Near Lahser and 11 Mile roads, M-10 meets I-696 (Reuther Freeway) and US 24 (Telegraph Road) in a complex interchange called the Mixing Bowl. This interchange spans over near the American Center. The carriageways for I-696 run in the median of M-10 while partial interchanges connect to Lahser and Franklin roads on either end of the various ramps that connect to I-696 and US 24. Northwest of this interchange, M-10 transitions to a boulevard with Michigan lefts. Called just Northwestern Highway, M-10 runs through suburban residential areas of Southfield. At the intersection with Inkster Road, the highway clips the southwest corner of the city of Franklin and enters the northeastern corner of Farmington Hills. The roadway is lined with commercial properties while just behind them are residential subdivisions and two golf courses. At the intersection with 14 Mile Road, Northwestern Highway crosses into West Bloomfield Township, and further on, the highway ends at Orchard Lake Road. History Previous designations In 1919, the state numbered its highways for the first time.

From there, the highway turned north along Woodward Avenue through Pontiac and Dixie Highway through Flint and Saginaw to Bay City. Then M-10 ran along the Saginaw Bay to Standish and turned to follow the Lake Huron shoreline, with some substantial deviations inland. The highway generally followed the lakeshore as far north as Alpena and Rogers City, and from there, M-10 ran due west through Onaway before turning north into Cheboygan. The last section of M-10 followed the Lake Huron shoreline to Mackinaw City, where it terminated.
