The U.S. Roads Portal
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, the Northern Mariana Islands, 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 numbers. 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.
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. Native American tribes may designate byways as well.

Interstate 70 (I-70) is a transcontinental Interstate Highway in the United States, stretching from Cove Fort, Utah, to Baltimore, Maryland. In Colorado, the highway traverses an east–west route across the center of the state. In western Colorado, the highway connects the metropolitan areas of Grand Junction and Denver via a route through the Rocky Mountains. In eastern Colorado, the highway crosses the Great Plains, connecting Denver with metropolitan areas in Kansas and Missouri. Bicycles and other non-motorized vehicles, normally prohibited on Interstate Highways, are allowed on those stretches of I-70 in the Rockies where no other through route exists.
The United States Department of Transportation (USDOT) lists the construction of I-70 among the engineering marvels undertaken in the Interstate Highway System and cites four major accomplishments: the section through the Dakota Hogback, Eisenhower Tunnel, Vail Pass, and Glenwood Canyon. The Eisenhower Tunnel, with a maximum elevation of 11,158 feet (3,401 m) and length of 1.7 miles (2.7 km), is the longest mountain tunnel and highest point along the Interstate Highway System. The portion through Glenwood Canyon was completed on October 14, 1992. This was one of the final pieces of the Interstate Highway System to open to traffic and is one of the most expensive rural highways per mile built in the country. The Colorado Department of Transportation (CDOT) earned the 1993 Outstanding Civil Engineering Achievement Award from the American Society of Civil Engineers for the completion of I-70 through the canyon.

State Route 520 (SR 520) is a state highway and freeway in the Seattle metropolitan area, part of the U.S. state of Washington. It runs 13 miles (21 km) from Seattle in the west to Redmond in the east. The freeway connects Seattle to the Eastside region of King County via the Evergreen Point Floating Bridge on Lake Washington. SR 520 intersects several state highways, including Interstate 5 (I-5) in Seattle, I-405 in Bellevue, and SR 202 in Redmond.
The original floating bridge was opened in 1963 as a replacement for the cross-lake ferry system that had operated since the late 19th century. In 1964, SR 520 was designated as a freeway connecting I-5 to I-405. An extension to Redmond was proposed later in the decade. In the 1970s and 1980s, sections of the freeway between Bellevue and Redmond were opened to traffic, replacing the temporary designation of SR 920. (Full article...) -
Interstate 80 (I-80) is a transcontinental Interstate Highway in the United States, stretching from San Francisco, California, to Teaneck, New Jersey. In Iowa, the highway travels west to east through the center of the state. It enters the state at the Missouri River in Council Bluffs and heads east through the southern Iowa drift plain. In the Des Moines metropolitan area, I-80 meets up with I-35 and the two routes bypass Des Moines together. On the northern side of Des Moines, the Interstates split and I-80 continues east. In eastern Iowa, it provides access to the University of Iowa in Iowa City. Northwest of the Quad Cities in Walcott is Iowa 80, the world's largest truck stop. I-80 passes along the northern edge of Davenport and Bettendorf and leaves Iowa via the Fred Schwengel Memorial Bridge over the Mississippi River into Illinois.
Before I-80 was planned, the route between Council Bluffs and Davenport, which passed through Des Moines, was vital to the state. Two competing auto trails, the Great White Way and the River-to-River Road, sought to be the best path to connect three of the state's major population centers. The two trails combined in the 1920s and eventually became US Highway 32 (US 32) in 1926. US 6, which had taken the place of US 32, became the busiest highway in the state. In the early 1950s, plans were drawn up for the construction of an Iowa Turnpike, to be the first modern four-lane highway in the state, along the US 6 corridor. Plans for the turnpike were shelved when the Interstate Highway System was created in 1956. (Full article...) -
Brockway Mountain Drive is an 8.8-mile-long (14.2 km) scenic roadway just west of Copper Harbor in the Upper Peninsula of Michigan in the United States. Drivers can access the road from State Highway M-26 on either end near Eagle Harbor to the west or Copper Harbor to the east in the Keweenaw Peninsula. The drive runs along the ridge of Brockway Mountain on the Keweenaw Fault and climbs to 1,320 feet (402 m) above sea level, 720 feet (219 m) above the surface of Lake Superior. Several viewpoints along the route allow for panoramas of Copper Harbor, Lake Superior, and undeveloped woodland. On a clear day, Isle Royale is visible approximately 50 miles (80 km) in distance from the top of the mountain.
Brockway Mountain was named for Daniel D. Brockway, one of the pioneer residents of the area. The road was constructed by the county road commission with funding through Depression-era work programs in 1933. It was briefly used as a connection for the parallel state highway after it opened. Since it opened, Brockway Mountain Drive has been recognized nationally and locally in several media outlets for its picturesque qualities, usually in profiles of Keweenaw County, the Upper Peninsula or other scenic drives.

Interstate 470 (I-470) is a 10.63-mile-long (17.11 km) auxiliary Interstate Highway of I-70 that bypasses the city of Wheeling, West Virginia, United States. I-470 is one of 13 auxiliary Interstate Highways in Ohio and the only auxiliary Interstate Highway in West Virginia. The western terminus of I-470 is an interchange with I-70 in Richland Township, Ohio. Traveling southeast through rural Belmont County, I-470 approaches the Vietnam Veterans Memorial Bridge, which spans the Ohio River. After crossing the river into Ohio County, West Virginia, the highway continues east toward the Wheeling communities of Bethlehem and Elm Grove and its eastern terminus at I-70 near Elm Grove. The portion of the highway in West Virginia is named the USS West Virginia Memorial Highway by proclamation of then-Governor Cecil H. Underwood on the 59th anniversary of the attack on Pearl Harbor.
Construction of the freeway began in 1975 in the two states. Due to a chronic lack of funding, construction in Ohio was stalled between 1976 and 1981. After a $0.033-per-US-gallon ($0.040/imp gal; $0.0087/L) fuel tax increase, Ohio was able to restart construction, and, by 1983, both states had completed construction on the freeway. The three-level diamond interchange with concurrent highways U.S. Route 250 (US 250) and West Virginia Route 2 (WV 2) on the eastern banks of the Ohio River was thought to be the most complex interchange in West Virginia's Interstate Highway System at the time of construction. On average, between 25,500 and 37,840 vehicles use the highway daily. (Full article...) -
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. (Full article...) -
Interchange with I-55 in Bolingbrook, formerly the southern terminus of I-355
Interstate 355 (I-355), also known as the Veterans Memorial Tollway, is an Interstate Highway and tollway in the western and southwest suburbs of Chicago in the U.S. state of Illinois. Like most other toll roads in the northeastern portion of the state, I-355 is maintained by the Illinois State Toll Highway Authority (ISTHA). I-355 runs from I-80 in New Lenox north to I-290 in Itasca, a distance of 32.5 miles (52.3 km). With the exception of a four-mile (6.4 km) expansion in 2009, from U.S. Route 34 (US 34, Ogden Avenue) to 75th Street, the highway is six lanes wide for its entire length.
The tollway authority opened I-355 as the North–South Tollway in 1989 to ease congestion on Illinois Route 53 (IL 53), a parallel two-lane state highway in central DuPage County. Initially, I-355 ran from I-55 north to I-290. The new highway helped cut travel times for commuters traveling north and south in the county. According to commercial real estate developers at the time, the new tollway also opened the western suburbs of Chicago to commercial and industrial development. (Full article...) -
Interstate 182 (I-182) is an east–west auxiliary Interstate Highway in the U.S. state of Washington. It serves as a connector from I-82 to the Tri-Cities region that crosses the Columbia River on the Interstate 182 Bridge between Richland and Pasco. I-182 is 15 miles (24 km) long and entirely concurrent with U.S. Route 12 (US 12); it also intersects State Route 240 (SR 240) and US 395.
Business leaders in the Tri-Cities began lobbying for a freeway in 1958 after early alignments for I-82 were routed away from the area. I-182 was created by the federal government in 1969 as a compromise to the routing dispute, which allowed for direct access to the Tri-Cities and a bypass for other traffic. The new freeway would also include construction of a bridge between Richland and Pasco, proposed since the 1940s at the site of an earlier cable ferry that ran until 1931. (Full article...) -
Interstate 70 (I-70) is a portion of the Interstate Highway System that runs from near Cove Fort, Utah, at a junction with I-15 to Baltimore, Maryland. It crosses the Northern Panhandle of West Virginia through Ohio County and the city of Wheeling. This segment is the shortest of all states through which I-70 passes, crossing West Virginia for only 14.45 miles (23.26 km). The Fort Henry Bridge carries I-70 from Wheeling Island across the Ohio River and into downtown Wheeling before the freeway enters the Wheeling Tunnel. I-470, a southerly bypass of Wheeling and the lone auxiliary Interstate Highway in West Virginia, is intersected near Elm Grove. Before crossing into Pennsylvania, I-70 passes The Highlands, a major shopping center in the panhandle, and the Bear Rocks Lake Wildlife Management Area. On average, between 27,000 and 53,000 vehicles use the freeway every day.
The first road that entered Wheeling was a post road completed in 1794 that connected Wheeling to Morgantown. The National Road was the first interstate road, completed in 1818, that connected Wheeling to Cumberland, Maryland. When the United States Numbered Highway System was created in 1926, the National Road was designated U.S. Route 40 (US 40). The I-70 designation was brought to the Northern Panhandle with the passage of the Federal-Aid Highway Act of 1956, and it was built as a controlled-access highway, bypassing portions of the old National Road. The first portions of I-70 in West Virginia were opened in 1963, and construction was completed in 1971. (Full article...) -
Interstate 40 (I-40) is part of the Interstate Highway System that runs 2,556.61 miles (4,114.46 km) from Barstow, California, to Wilmington, North Carolina. The highway crosses Tennessee from west to east, from the Mississippi River at the Arkansas border to the Blue Ridge Mountains at the North Carolina border. At 455.28 miles (732.70 km), the Tennessee segment of I-40 is the longest of the eight states through which it passes and the state's longest Interstate Highway.
I-40 passes through Tennessee's three largest cities—Memphis, Nashville, and Knoxville—and serves the Great Smoky Mountains National Park, the most-visited national park in the United States. It crosses all of Tennessee's physiographic regions and Grand Divisions—the Mississippi embayment and Gulf Coastal Plain in West Tennessee, the Highland Rim and Nashville Basin in Middle Tennessee, and the Cumberland Plateau, Cumberland Mountains, Ridge-and-Valley Appalachians, and Blue Ridge Mountains in East Tennessee. Landscapes on the route vary from flat, level plains and swamplands in the west to irregular rolling hills, cavernous limestone bluffs, and deep river gorges in the central part of the state, to plateau tablelands, broad river valleys, narrow mountain passes, and mountain peaks in the east.

View of the route, 1920
The Ridge Route, officially the Castaic–Tejon Route and colloquially known as the Grapevine, was a two-lane highway between Los Angeles County and Kern County, California. Opened in 1915 and paved with concrete between 1917 and 1921, the road was the first paved highway directly linking the Los Angeles Basin with the San Joaquin Valley (southern Central Valley) over the Tejon Pass and the rugged Sierra Pelona Mountains ridge south of Gorman. Much of the old road runs through the Angeles National Forest, and passes many historical landmarks, including the National Forest Inn, Reservoir Summit, Kelly's Half Way Inn, Tumble Inn, and Sandberg's Summit Hotel. North of the forest, the Ridge Route passed through Deadman's Curve before ending at Grapevine.
The road was bypassed by the three-lane Ridge Route Alternate, then U.S. Route 99 (US 99), to handle increased traffic and remove curves; the Alternate in Los Angeles County was completed in 1933, and Kern County line to Grapevine in 1936. The four-lane US 99 was completed in 1953 and replaced by an eight-lane freeway, Interstate 5 (I-5) in 1960-70. The portion of the road in the Angeles National Forest was added to the National Register of Historic Places in 1997, by the efforts of Harrison Scott. Much of the road has been closed by the U.S. Forest Service; other remnants are used by local traffic. (Full article...) -
New York State Route 175 (NY 175) is an east–west state highway located entirely within Onondaga County, New York, in the United States. The 15.46-mile (24.88 km) route begins at an intersection with U.S. Route 20 (US 20) east of the village of Skaneateles and passes through the village of Marcellus before ending at a junction with US 11 in Syracuse. The highway was designated in the 1930 renumbering of state highways in New York.
The section of NY 175 from the town of Marcellus to the end of the NY 173 concurrency is part of the Seneca Turnpike, which was established in 1800 and dissolved in 1852. This portion of the Seneca Turnpike was instrumental in the development of the villages of Skaneateles and Marcellus. When designated in 1930, NY 175 was on a rural stretch of highway connecting Marcellus to Onondaga, and brought about an increase in population and development along its route. (Full article...) -
Interstate 75 (I-75) is a part of the Interstate Highway System that runs north–south from Miami, Florida, to Sault Ste. Marie in the Upper Peninsula of the US state of Michigan. I-75 enters the state from Ohio in the south, north of Toledo, and runs generally northward through Detroit, Flint, and Bay City, crosses the Mackinac Bridge, and ends at the Canadian border in Sault Ste. Marie. The freeway runs for approximately 396 miles (637 km) on both of Michigan's major peninsulas. The landscapes traversed by I-75 include Southern Michigan farmland, northern forests, suburban bedroom communities, and the urban core of Detroit. The freeway also uses three of the state's monumental bridges to cross major bodies of water. There are four auxiliary Interstates in the state related to I-75, as well as nine current or former business routes, with either Business Loop I-75 (BL I-75) or Business Spur I-75 (BS I-75) designations.
The freeway bears several names in addition to the I-75 designation. The southern segment was called the Detroit–Toledo Expressway during planning in the 1950s and 1960s. Through Detroit, I-75 is the Fisher Freeway or the Walter P. Chrysler Freeway, named for pioneers in the auto industry. Sections on either side of the Mackinac Bridge are the G. Mennen Williams Freeway or the Prentiss M. Brown Freeway, named for politicians who helped get the bridge built. Officially, the entire length is the American Legion Memorial Highway, after the organization of the same name. Various sections carry components of the four Great Lakes Circle Tours in the state.

State Route 78 (SR 78) is a state highway in the U.S. state of California that runs from Oceanside east to Blythe, traversing nearly the entire width of the state. Its western terminus is at Interstate 5 (I-5) in San Diego County and its eastern terminus is at I-10 in Riverside County. The route is a freeway through the heavily populated cities of northern San Diego County and a two-lane highway running through the Cuyamaca Mountains to Julian. In Imperial County, SR 78 travels through the desert near the Salton Sea and passes through the city of Brawley and the Algodones Dunes before turning north on the way to its terminus in Blythe.
SR 78 was one of the original state highways designated in 1934, although portions of the route existed as early as 1900. However, it was not designated east of Brawley until 1959. The freeway section in the North County of San Diego that connects Oceanside and Escondido was built in the middle of the twentieth century in several stages, including a transitory stage known as the Vista Way Freeway, and has been altered several times. An expressway bypass of the city of Brawley was completed in 2012. There are many projects slated to add capacity to the freeway due to increasing congestion in the region. (Full article...) -
Interstate 80 Business (I-80 Bus.) is an unofficial business loop of Interstate 80 (I-80) that is 2.26 miles (3.64 km) long and serves as the main street for the US cities of West Wendover, Nevada, and Wendover, Utah, along a roadway named Wendover Boulevard. Wendover Boulevard was originally part of US Route 40 (US 40), which connected California to New Jersey via Nevada and Utah. A portion of the Nevada segment runs concurrently with US 93 Alternate (US 93 Alt.), and the entire portion in Utah is coterminous with State Route 58 (SR-58). The Nevada Department of Transportation (NDOT) applied for the business loop designation in the early 1980s, but the designation has never been approved; nevertheless, signs are posted in both states. Between July 1976 and 1993, I-80 Bus was concurrent with State Route 224 (SR 224) in Nevada. (Full article...)

Interstate 380 (I-380) is a 73-mile (117 km) auxiliary Interstate Highway in eastern Iowa. The route extends from I-80 near Coralville to Waterloo. I-380 connects the cities of Cedar Rapids and Waterloo, the state's second- and sixth-largest cities, respectively, to the Interstate Highway System. Except for its last 1.5 miles (2.4 km) north of U.S. Highway 20 (US 20), I-380 runs concurrently with Iowa Highway 27 (Iowa 27), which represents Iowa's portion of the 560-mile (900 km) Avenue of the Saints highway connecting Saint Louis, Missouri, with Saint Paul, Minnesota.
Construction of I-380 took 12 years to complete, ending in 1985. After the Interstate opened, US 218 was moved onto the new freeway south of Cedar Rapids. In the 1990s, the I-380 corridor was selected as part of the Avenue of the Saints corridor, which Iowa designated as Iowa 27 in 2001. I-380 has been affected by two major floods, the Great Flood of 1993 and the Iowa flood of 2008, both of which closed the road at the Iowa River for two weeks. (Full article...) -
State Route 778 (SR 778, OH 778) is a short north–south state highway in northern Ohio. The southern terminus of SR 778 is at SR 101 approximately 9 miles (14 km) northeast of Tiffin. The highway's northern terminus is at SR 19 about 3 miles (4.8 km) south of Green Springs. The route was created in 1942 and has not changed since. (Full article...)

Mississippi Highway 365 (MS 365) is a state highway in northeastern Mississippi. The route starts at MS 30 in Burton and travels northward. It travels into Burnsville and intersects U.S. Route 72 (US 72). MS 365 continues northeastward and ends at MS 25 west of Pickwick Lake. The route was designated by 1950, connecting from MS 30 to MS 364. It was extended northward to MS 356 around 1958 and was completely paved by 1964. The route replaced parts of MS 356 in 1965, and its northern terminus was changed to MS 25. (Full article...)

New York State Route 7 (NY 7) is a 180.30-mile-long (290.16 km) state highway in New York in the United States. The highway runs from Pennsylvania Route 29 (PA 29) at the Pennsylvania state line south of Binghamton in Broome County, New York, to Vermont Route 9 (VT 9) at the Vermont state line east of Hoosick in Rensselaer County. Most of the road runs along the Susquehanna Valley, closely paralleling Interstate 88 (I-88) throughout that road's length. Portions of the highway route near the cities of Binghamton, Schenectady, and Troy date back to the early 19th century. (Full article...)

M-18 is a north–south state trunkline highway in the Lower Peninsula of the US state of Michigan. It runs for 77.530 miles (124.772 km) through the central region of the state connecting US Highway 10 (US 10) near North Bradley with M-72 in rural Crawford County near the community of Luzerne. In between, the roadway connects several smaller communities while running through woodlands in both state and national forest areas. Two segments of M-18 run along sections of county boundaries, and one part of the highway forms a component of the business loop for the village of Roscommon.
When the highway was first designated in the late 1910s, it extended farther south than it does today and ended well short of its current northern terminus. The southern end was added to another state highway, truncating M-18's length to roughly its current southern terminus in 1926. The northern end was also simultaneously extended for the first time with these revisions to the highway's routing. In the 1940s, the northern extension was reversed and then reinstated. M-18's course was last changed with the opening of three different freeways in the area in the 1960s and 1970s. The last extension in 1973 supplanted the M-144 designation from Roscommon north to Luzerne. (Full article...) -
New York State Route 375 (NY 375), locally known as West Hurley Road for its entire length, is a short highway in the Catskill Park located entirely within Ulster County, New York, in the United States. It primarily allows for more direct access from nearby Kingston to Woodstock. It runs north–south from NY 28 at West Hurley to near the business district of Woodstock, where it terminates at another state highway, NY 212. The route was designated in the 1930 renumbering in New York, replacing a piece of legislative Route 5 from 1908 and has remained unchanged since. (Full article...)

State Route 18 (SR 18) is a 28.41-mile-long (45.72 km) state highway in the U.S. state of Washington, serving southeastern King County. The highway travels northeast, primarily as a controlled-access freeway, from an intersection with SR 99 and an interchange with Interstate 5 (I-5) in Federal Way through the cities of Auburn, Kent, Covington, and Maple Valley. SR 18 becomes a two-lane rural highway near Tiger Mountain as it approaches its eastern terminus, an interchange with I-90 near the cities of Snoqualmie and North Bend.
SR 18 was established during the 1964 state highway renumbering as the successor to the Auburn–Federal Way branch of Primary State Highway 5 (PSH 5) and the Auburn–North Bend branch of PSH 2, which were created in 1931 and 1949, respectively. The initial two-lane highway, named the Echo Lake Cutoff, was completed in December 1964 after the opening of a section around Tiger Mountain, which would later be the site of over 170 accidents in the 1980s. SR 18 was gradually widened into a four-lane freeway beginning in Auburn in 1992 and most recently finishing in Federal Way in 2007. The highway around Tiger Mountain and near the I-90 interchange remains a two-lane road, with a funded project planned to re-build the existing interchange with I-90. (Full article...) -
State Route 169 (SR 169) is a state highway in the U.S. state of Washington, located entirely within King County. It runs 25 miles (40 km) from Enumclaw to Renton, passing through Black Diamond and Maple Valley. The highway, also known as the Maple Valley Highway, functions as a major rural and suburban route for the southeastern Seattle metropolitan area and connects several highways, including SR 410, SR 18, and Interstate 405 (I-405).
The Enumclaw–Maple Valley–Renton highway was built in 1914 and expanded in the early 1930s by the county government. It was absorbed into the state highway system in 1937 and designated as a branch of Primary State Highway 5 and renumbered to SR 169 in 1964. Recent residential development in Maple Valley and surrounding areas has increased traffic congestion on the highway, leading to a series of widening and improvement projects funded primarily by city governments.

New York State Route 171 (NY 171) is a state highway running east to west through Herkimer County, New York, in the United States. It connects the hamlet of Gulph in the town of Frankfort to the village of Frankfort by way of the Frankfort Gorge. Its western end is at the junction of County Route 145 (CR 145) and CR 185 southeast of Gulph. The eastern end is 5.69 miles (9.16 km) to the east at an intersection with Main Street in Frankfort village. NY 171 is a narrow, two-lane highway for its whole length.
NY 171 is the only signed state highway in New York that does not intersect any other signed New York state routes. However, this was not always the case. When it was originally assigned as part of the 1930 renumbering of state highways in New York, Main Street in Frankfort was part of NY 5S. A new freeway alignment for NY 5S was constructed between Utica and Ilion in the late 1960s, isolating NY 171 from the remainder of the state highway system. Frankfort's interchange with NY 5S is now at Cemetery Street, 0.75 miles (1.21 km) to the west. (Full article...) -
Sierra Highway or El Camino Sierra is a road in Southern California, United States. El Camino Sierra refers to the full length of a trail formed in the 19th century, rebuilt as highways in the early 20th century, that ran from Los Angeles to Lake Tahoe following parts of modern State Route 14, U.S. Route 395 and State Route 89. Two portions of this road are currently signed as Sierra Highway. The first is an old alignment of SR 14/U.S. Route 6 from Los Angeles to Mojave. This road is also signed with the unusual designation of State Route 14U through the city of Santa Clarita. The second part signed as Sierra Highway is a portion of US 395 in Bishop.
Traversing the extremes of California, from the Mojave Desert to the Sierra Nevada, El Camino Sierra has been advertised to the world as a highway to showcase the natural beauty of California as far back as 1910. Though most of Sierra Highway was bypassed in the early 1970s with freeways, the road is still well known.

Mississippi Highway 24 (MS 24) is a state highway in Mississippi, United States. The highway runs 76.0 miles (122.3 km) from Fort Adams east to an interchange with Interstate 55 (I-55) and U.S. Highway 98 (US 98) in McComb. The roadway passes through Wilkinson, Amite, and Pike counties, serving the communities of Woodville, Centreville, Gloster, and Liberty. MS 24 has concurrencies with MS 33 between Centerville and Gloster and MS 48 from Liberty to west of McComb.
MS 24 was designated in 1932 to run from Fort Adams east to Leakesville, following gravel roads across the southern part of the state. Throughout the 1930s and 1940s, much of the route was paved and realigned. The route was extended from Leakesville to the Alabama border in 1953. US 98 replaced the MS 24 designation from McComb to east of McLain in 1955, splitting MS 24 into two segments. The eastern segment was redesignated MS 594 in 1958. The eastern terminus was moved to its current location in 1967, with US 98 replacing the part leading into McComb. (Full article...) -
U.S. Route 202 (US 202) is a U.S. Highway running from New Castle, Delaware northeast to Bangor, Maine. In the U.S. state of New Jersey, the route runs 80.31 mi (129.25 km) from the New Hope–Lambertville Toll Bridge over the Delaware River at the Pennsylvania border in Delaware Township, Hunterdon County near Lambertville northeast to the New York border in Mahwah, Bergen County. Along the route's journey, it passes through a variety of suburban and rural environments, including the communities of Flemington, Somerville, Morristown, Parsippany-Troy Hills, Wayne, and Oakland as well as five counties: Hunterdon, Somerset, Morris, Passaic, and Bergen. US 202 encounters many major roads in New Jersey, including Route 31, US 206, US 22, Interstate 80 (I-80), US 46, Route 23, and Route 17. From Somerville to the New York border, US 202 generally runs within a close distance of I-287 and interchanges with that route several times. The road ranges from a four-lane freeway between Lambertville and Ringoes in Hunterdon County to a two-lane surface road through much of the northern portion of the route. North of the Route 53 intersection in Morris Plains, US 202 is maintained by individual counties rather than the New Jersey Department of Transportation with a few exceptions.
In the original system of New Jersey state highways, present-day U.S. Route 202 was legislated as pre-1927 Route 5 between Morristown and Morris Plains in 1916 and as pre-1927 Route 16 between Somerville and Morristown in 1921. In 1927, the current route was designated as Route 29 between Lambertville and Ringoes, Route 30 (now Route 31) between Ringoes and Flemington, Route 12 between Flemington and Somerville, Route 31 (now U.S. Route 206) between Somerville and Bedminster, Route 32 between Bedminster and Mountain View, and Route 23 within a portion of Wayne. Meanwhile, US 122 was signed in New Jersey to run from the New Hope–Lambertville Bridge in Lambertville, where the route continued south to State Road, Delaware, along Bridge Street, Route 29, and Route 30 to Flemington, and then along present-day County Route 523 (CR 523) to US 22 in White House. In 1934, US 122 was renumbered to US 202, and realigned to follow its current route to New York border near Suffern, New York where it continued to Bangor, Maine. In 1953, all the state highway designations were removed from US 202 except for Route 23 and Route 30 (which became Route 69 before becoming Route 31 in 1967) to avoid long concurrencies with the route. In the 1960s, plans were made to upgrade US 202 to a freeway between the Pennsylvania border and I-287 in Bridgewater Township. The only parts of this freeway that were completed were a bypass of Ringoes in the 1960s and a freeway between the Delaware River and Ringoes in 1974; the rest was canceled due to opposition from residents along the route. With the completion of the US 202 freeway in Hunterdon County, the former alignment became Route 179. The portion of US 202 concurrent with Route 23 in Wayne was upgraded from a four-lane road to a six-lane road in the 1980s. (Full article...) -
New York State Route 16 (NY 16) is a state highway in western New York, in the United States. It runs from the Pennsylvania state line, where it is one of the highest highways in the state in elevation, to downtown Buffalo. NY 16 is a major route through Erie County, despite the construction of the paralleling NY 400 freeway from East Aurora. In Cattaraugus County it also plays an important role, serving as the major connection from Olean to the Southern Tier Expressway (Interstate 86 or I-86 and NY 17). Between those two areas, and indeed for much of its length, it is a two-lane rural road.
NY 16 initially ended in Olean when it was assigned in 1924. It was extended south to the Pennsylvania state line in the early 1930s; however, it initially overlapped NY 17 east to Portville, where it connected to Pennsylvania by way of modern NY 305. NY 16's current alignment south of Olean was originally designated as New York State Route 16A around this time. NY 16 was rerouted to follow the routing of NY 16A south of Olean in August 1962.
