The Detroit metropolitan area in southeast Michigan is served by a comprehensive network of roads and highways. Three primary Interstate Highways pass through the region, along with three auxiliary Interstates, and multiple state and U.S. Highways.[2] These are supplemented by the Mile Road System, a series of local roads spaced one mile apart on a perpendicular grid.

Many of the grid's east-west roads are known by numbers, such as 8 Mile Road, the system's baseline and Detroit's northern border. Intersecting this grid are five diagonal spokes, major arterial roads which travel from downtown to the suburbs. Most major roads in the city and suburbs follow this grid, though streets in some areas (particularly within Detroit, and near Lake St. Clair and other lakes) deviate.
