Roads In The United States
Highways in the United States are split into at least four different types of systems.
- Interstate Highways
- The Interstate Highway System is a federally funded and administered (but state-maintained) system of freeways that forms the transportation backbone of the U.S., with millions of Americans relying on it for commutes and freight transport daily. Interstate highways are all constructed to precise standards, designed to maximize high-speed travel safety and efficiency. Interstate Highways also contain auxiliary routes, which are normally assigned a three-digit route number. All Interstate Highways are part of the National Highway System, a network of highways deemed essential to the defense, economy, and mobility of the country.
- U.S. Highways
- The U.S. Highway System (officially "United States Numbered Highways") is an older system consisting mostly of surface-level trunk roads, coordinated by the American Association of State Highway and Transportation Officials and maintained by state and local governments. U.S. highways have been relegated to regional and intrastate traffic, as they have been largely supplanted by the Interstate system for long-distance travel except in areas (especially in the west) where the Interstate system is absent or underdeveloped. This has led to the decommissioning and truncation of U.S. Highways that were formerly vital long-haul routes, such as U.S. Route 21 and U.S. Route 66.
- State Highways
- Each state also has a state highway system. State highways are of varying standards and quality. Some state highways become so heavily traveled they are built to Interstate Highway standards. Others are so lightly traveled that they are roads of low quality.
- County Highways
- The final administrative level in some states is the county-maintained county highway. (The term "parish" is used instead in Louisiana.) County routes vary widely from well-traveled multilane highways to dirt roads into remote parts of the county.
Highways are generally organized by a route number or letter. These designations are generally displayed along the route by means of a highway shield. Each system has its own unique shield design that will allow quick identification to which system the route belongs. Below is a list of the different highway shields used throughout the U.S.

Famous quotes containing the words united states, roads, united and/or states:
“I feel most at home in the United States, not because it is intrinsically a more interesting country, but because no one really belongs there any more than I do. We are all there together in its wholly excellent vacuum.”
—Wyndham Lewis (1882–1957)
“Other roads do some violence to Nature, and bring the traveler to stare at her, but the river steals into the scenery it traverses without intrusion, silently creating and adorning it, and is as free to come and go as the zephyr.”
—Henry David Thoreau (1817–1862)
“America—rather, the United States—seems to me to be the Jew among the nations. It is resourceful, adaptable, maligned, envied, feared, imposed upon. It is warm-hearted, overfriendly; quick-witted, lavish, colorful; given to extravagant speech and gestures; its people are travelers and wanderers by nature, moving, shifting, restless; swarming in Fords, in ocean liners; craving entertainment; volatile. The schnuckle among the nations of the world.”
—Edna Ferber (1887–1968)
“We cannot feel strongly toward the totally unlike because it is unimaginable, unrealizable; nor yet toward the wholly like because it is stale—identity must always be dull company. The power of other natures over us lies in a stimulating difference which causes excitement and opens communication, in ideas similar to our own but not identical, in states of mind attainable but not actual.”
—Charles Horton Cooley (1864–1929)
