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.

The trunkline is the dividing line between Detroit's East and West sides and connects to some of the city's major freeways like Interstate 94 (I-94, Edsel Ford Freeway) and M-8 (Davison Freeway). Woodward Avenue exits Detroit at M-102 (8 Mile Road) and runs through the city's northern suburbs in Oakland County on its way to Pontiac. In between, Woodward Avenue passes through several historic districts in Detroit and provides access to many businesses in the area. The name Woodward Avenue has become synonymous with Detroit, cruising culture and the automotive industry.

The Huron River is a 130-mile-long (210 km) river in southeastern Michigan, rising out of the Huron Swamp in Springfield Township in northern Oakland County and flowing into Lake Erie, as it forms the boundary between present-day Wayne and Monroe counties. Thirteen parks, game areas, and recreation areas are associated with the river, which passes through the cities of Dexter, Ann Arbor, Ypsilanti, Belleville, Flat Rock and Rockwood that were developed along its banks.

The Huron River is a typical Southeast Michigan stream; mud banks, slow stream flow and a low gradient define this river. It runs through the following counties, in order from the headwaters to its mouth: Oakland, Livingston, Washtenaw, Wayne, and Monroe. There are 24 major tributaries totaling about 370 miles (600 km) in addition to the mainstream. The Huron River watershed drains 908 square miles (2,350 km). It is the only state-designated Country-Scenic Natural River in southeast Michigan. This includes 27.5 miles (44.3 km) of the mainstream, plus an additional 10.5 miles (16.9 km) of three tributaries.

The River Rouge is a 127-mile (204 kilometer) river in the Metro Detroit area of southeastern Michigan. It flows into the Detroit River at Zug Island, which is the boundary between the cities of River Rouge and Detroit.

The river's roughly 467-square-mile (1,210 km) watershed includes all or parts of 48 municipalities, with a total population of more than 1.35 million, and it drains a large portion of central and northwest Wayne County, as well as much of southern Oakland County and a small area in eastern Washtenaw County. Nearly the entire drainage basin is in urban and suburban areas, with areas of intensive residential and industrial development. Still, more than 50 miles (80 km) of the River Rouge flow through public lands, making it one of the most accessible rivers in the state.
