The highway system of the United States is a network of interconnected state, U.S., and Interstate highways. Each of the fifty states, the District of Columbia, Puerto Rico, American Samoa, Guam, and the U.S. Virgin Islands own and maintain a part of this vast system, including U.S. and Interstate highways, which are not owned or maintained at the federal level.

Interstate Highways have the highest speed limits and the highest traffic. Interstates are numbered in a grid: even-numbered routes for east–west routes (with the lowest numbers along Mexico and the Gulf of Mexico), and odd-numbered routes are north–south routes (with the lowest numbers along the Pacific Ocean). Three-digit Interstates are, generally, either beltways or spurs of their parent Interstates (for example, Interstate 510 is a spur into the city of New Orleans, Louisiana, and is connected to Interstate 10).

U.S. Numbered Highways are the original interstate highways, dating back to 1926. U.S. Highways are also numbered in a grid: even numbered for east–west routes (with the lowest numbers along Canada) and odd numbered for north–south routes (with the lowest numbers along the Atlantic Ocean). Three-digit highways, also known as "child routes," are branches off their main one- or two-digit "parents" (for example, U.S. Route 202 is a branch of U.S. Route 2). However, US 101, rather than a "child" of US 1, is considered a "mainline" U.S. Route.

State highways are the next level in the hierarchy. Each state and territory has its own system for numbering highways, some more systematic than others. Each state also has its own design for its highway markers; the number in a circle is the default sign, but many choose a different design connected to the state, such as an outline of the state with the number inside. Many states also operate a system of county highways.

National Forest Scenic Byway marker

Scenic byways can be designated over any classification of road in the United States. There are the National Scenic Byways, National Forest Scenic Byways and Bureau of Land Management Back Country Byways at the national level. Most states have their own system for designating byways, some more systematic than others. Indian tribes may designate byways as well.

Woodward Dream Cruise along Woodward Avenue (M-1)

M-1, commonly 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. 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. Woodward Avenue was created after the Detroit Fire of 1805. The thoroughfare followed the route of the Saginaw Trail, an Indian trail that linked Detroit with Pontiac, Flint, and Saginaw. In the age of the auto trails, Woodward Avenue was part of the Theodore Roosevelt International Highway that connected Portland, Maine, with Portland, Oregon, through Ontario in Canada. It was also part of the Dixie Highway, which connected Michigan with Florida. When Michigan created the State Trunkline Highway System in 1913, the roadway was included, numbered as part of M-10 in 1919. Later, it was part of US Highway 10 (US 10) following the creation of the United States Numbered Highway System. Since 1970, it has borne the M-1 designation.
