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.

US-412 east of Boise City

U.S. Route 412 (abbreviated US-412) is a U.S. highway in the south-central portion of the United States, connecting Springer, New Mexico to Columbia, Tennessee. A 504.11-mile (811.29 km) section of the highway crosses the state of Oklahoma, traversing the state from west to east. Entering the state southwest of Boise City, US-412 runs the length of the Oklahoma Panhandle and serves the northern portion of the state's main body, before leaving the state at West Siloam Springs. Along the way, the route serves many notable cities and towns, including Boise City, Guymon, Woodward, Enid, and the state's second-largest city, Tulsa. US-412 has two tolled sections—the Cimarron Turnpike and the Cherokee Turnpike. The tolled portions of the highway are operated by the Oklahoma Turnpike Authority (OTA), with the remainder of the route maintained by the Oklahoma Department of Transportation (ODOT). In addition to the freeway-grade turnpikes, a large amount of the highway has been upgraded to four-lane expressway facilities, although some portions remain two-lane, especially in the Panhandle. Much of US-412's route through Oklahoma either overlaps or is in close proximity to that of US-64. US-412 was extended into Oklahoma in 1988 to encourage recreational travel and the resulting economic benefit to the state. This extension, in which the new designation replaced or overlapped several already existing highways, brought US-412's western terminus to Woodward. In 1993, it was extended west of Oklahoma, bringing it through the Panhandle and into New Mexico.
