M-1, commonly known as Woodward Avenue, named for Augustus B. Woodward, is a north–south state trunkline in the US state of Michigan. Until a few years ago, the northern terminus of M-1 was at BL I-75 and BUS US 24 (Square Lake Road) in Bloomfield Township between the city limits of Bloomfield Hills and Pontiac in Oakland County. Woodward has now been extended north into central Pontiac over what once was called Wide Track Drive. The southern end of M-1 is in downtown Detroit at Adams Avenue; however, Woodward Avenue extends further south in Detroit to Jefferson Avenue.
