The Detroit Public Library is the second largest library system in the U.S. state of Michigan by volumes held and the 21st-largest library system in the United States. It is composed of the Main Library on Woodward Avenue, which houses the library's administration offices, and 23 branch locations across the city. The Main Library is part of Detroit's Cultural Center Historic District listed in the National Register of Historic Places adjacent to Wayne State University campus and across from the Detroit Institute of Arts.

M-1, also known as Woodward Avenue, is a north–south state trunkline highway in the Metro Detroit area of the US state of Michigan. The highway, called "Detroit's Main Street", runs from Detroit north-northwesterly to Pontiac. It is one of the five principal avenues of Detroit, along with Michigan, Grand River, Gratiot, and Jefferson avenues. These streets were platted in 1805 by Judge Augustus B. Woodward, namesake to Woodward Avenue. The Federal Highway Administration (FHWA) has listed the highway as the Automotive Heritage Trail, an All-American Road in the National Scenic Byways Program. It has also been designated a Pure Michigan Byway by the Michigan Department of Transportation (MDOT), and was also included in the MotorCities National Heritage Area designated by the US Congress in 1998.
