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 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 the state of Tennessee from west to east, from the Mississippi River at the Arkansas state line to the Blue Ridge Mountains at the North Carolina state line. 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. (Full article...)- Interstate 94 (I-94) is a part of the Interstate Highway System that runs from Billings, Montana, to the Lower Peninsula of the US state of Michigan. In Michigan, it is a state trunkline highway that enters the state south of New Buffalo and runs eastward through several metropolitan areas in the southern section of the state. The highway serves Benton Harbor–St. Joseph near Lake Michigan before turning inland toward Kalamazoo and Battle Creek on the west side of the peninsula. Heading farther east, I-94 passes through rural areas in the middle of the southern Lower Peninsula, crossing I-69 in the process. I-94 then runs through Jackson, Ann Arbor, and portions of Metro Detroit, connecting Michigan's largest city to its main airport. Past the east side of Detroit, the Interstate angles northeasterly through farmlands in The Thumb to Port Huron, where the designation terminates on the Blue Water Bridge at the Canada–United States border.
The first segment of what later became I-94 within the state, the Willow Run Expressway, was built near Ypsilanti and Belleville in 1941, with an easterly extension to Detroit in 1945. This expressway was initially numbered M-112. In the mid-1950s, state and federal officials planned an Interstate to replace the original route of US Highway 12 (US 12). By 1960, the length of I-94 was completed from Detroit to New Buffalo. Two years later, the US 12 designation was dropped from the freeway. Subsequent extensions in the 1960s completed most of the rest of the route, including the remaining sections between Detroit and Port Huron which superseded the routing of US 25. The last segment opened to the public in 1972 when Indiana completed its connection across the state line. Since completion, I-94 has remained relatively unchanged; a few interchanges have been rebuilt, a second span was constructed for the Blue Water Bridge, and, in 1987, a plane crashed on the freeway during takeoff from the airport in Detroit. The routing of I-94 is notable for containing the first full freeway-to-freeway interchange in the United States, connecting to the Lodge Freeway (M-10), and for comprising the first complete border-to-border toll-free freeway in a state in the United States. The highway has one auxiliary route, I-194, which serves downtown Battle Creek, and eight business routes. Various segments have been dedicated to multiple people and places. (Full article...) - The Capitol Loop was a state trunkline highway running through Lansing, Michigan, in the United States that was commissioned on October 13, 1989. It formed a loop route off Interstate 496 (I-496) through downtown near the Michigan State Capitol complex, home of the state legislature and several state departments. The Michigan Department of Transportation (MDOT) had labeled it as Capitol Loop I-496 or CL I-496 on some maps, similar to the Business Loop Interstate nomenclature. However, unlike other business loops in Michigan, it had unique reassurance markers—the signs that served as regular reminders of the name and number of the highway. It was known internally at MDOT as Connector 496 for inventory purposes. The route followed a series of one-way and two-way streets through downtown Lansing, directing traffic downtown to the State Capitol and other government buildings. Unlike the other streets downtown, the seven streets comprising the Capitol Loop were under state maintenance and jurisdiction.
The loop was originally proposed in 1986 as part of a downtown revitalization effort. Almost from the beginning before the highway was commissioned in 1989, it was affected by controversial proposals. Several suggestions by community leaders to rename city streets in honor of Martin Luther King Jr. were rejected. In the end, Logan Street was given a second name, Martin Luther King Jr. Boulevard, and the original name was eventually dropped. (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...) - US Highway 25 (US 25) was a part of the United States Numbered Highway System in the state of Michigan that ran from the Ohio state line near Toledo and ended at the tip of The Thumb in Port Austin. The general routing of this state trunkline highway took it northeasterly from the state line through Monroe and Detroit to Port Huron. Along this southern half, it followed undivided highways and ran concurrently along two freeways, Interstate 75 (I-75) and I-94. Near the foot of the Blue Water Bridge in Port Huron, US 25 turned north and northwesterly along the Lake Huron shoreline to Port Austin.
Created with the initial US Highway System on November 11, 1926, US 25 replaced several previous state highway designations. Some of the preceding highways followed roadways created in the 19th and the early 20th centuries. It initially was only routed as far north as Port Huron; the northern extension to Port Austin happened in 1933. By the end of the 1950s, the entire route was paved. Starting in the early 1960s, segments of I-75 and I-94 were built, and US 25 was shifted to follow them south of Detroit to Port Huron. A business loop was created when the main highway bypassed downtown Port Huron, and then in 1973, the entire designation was removed from the state. The final routing of the highway is still maintained by the state under eight different designations, some unsigned. (Full article...) - Interstate 205 (I-205) is an auxiliary Interstate Highway in the Portland metropolitan area of Oregon and Washington, United States. The north–south freeway serves as a bypass route of I-5 along the east side of Portland, Oregon, and Vancouver, Washington. It intersects several major highways and serves Portland International Airport.
The freeway is 37 miles (60 km) long and connects to I-5 at both of its termini: to the south in Tualatin, Oregon, and to the north in Salmon Creek, Washington. I-205 is named the Veterans Memorial Highway and East Portland Freeway No. 64 in Oregon (see Oregon highways and routes). From Oregon City to Vancouver, the corridor is paralleled by a multi-use bicycle and pedestrian trail, as well as portions of the MAX Light Rail system between Clackamas and northeastern Portland. (Full article...) - State Route 75 (SR 75) is a 13-mile (21 km) north-south state highway in San Diego County in the U.S. state of California. It is a loop route of Interstate 5 (I-5) that begins near Imperial Beach, heading west on Palm Avenue. The route continues north along the Silver Strand, a thin strip of land between the Pacific Ocean and San Diego Bay, through Silver Strand State Beach. SR 75 then passes through the city of Coronado as Orange Avenue and continues onto the San Diego–Coronado Bay Bridge, which traverses the bay, before joining back with I-5 near downtown San Diego.
The Silver Strand Highway was constructed and open to the public by 1924. What would become SR 75 was added to the state highway system in 1933, and designated Legislative Route 199 in 1935. SR 75 was not officially designated until the 1964 state highway renumbering. The Coronado Bay Bridge opened in 1969, and provided a direct connection between San Diego and Coronado. Since then, various proposals have taken place to relieve commuter traffic between San Diego and Naval Air Station North Island that traverses the city of Coronado. However, none of these proposals have gained support, including an attempt in 2010. (Full article...) - Interstate 675 (I-675) is an auxiliary Interstate Highway in the US state of Michigan. The freeway is a 7.7-mile-long (12.4 km) loop route through downtown Saginaw, as I-75 passes on the east side of the city. I-675 is also a state trunkline highway that provided a bypass of the former drawbridge carrying I-75 and US Highway 23 (US 23) across the Saginaw River. Construction of I-675 started in 1969 and the freeway opened in 1971. Since then, sections near downtown were reconstructed between 2009 and 2011 to update one of the freeway's interchanges and rebuild the bridge over the Saginaw River. (Full article...)
- 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...) - 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...)
- The Creek Turnpike, also designated State Highway 364 (SH-364), is a 33.2-mile (53.4 km) toll road that lies entirely in the U.S. state of Oklahoma. The controlled-access turnpike forms a partial beltway around the south and east sides of Tulsa, Oklahoma's second largest city. The Creek Turnpike's western terminus is at the Turner Turnpike in Sapulpa, while its northeastern terminus is at the Will Rogers Turnpike in Fair Oaks; both ends of the Creek Turnpike connect with Interstate 44 (I-44). Along the way, the highway passes through the cities of Sapulpa, Jenks, Tulsa, and Broken Arrow, and the counties of Creek, Tulsa, Wagoner and Rogers. The road is maintained by the Oklahoma Turnpike Authority (OTA), except for a brief free section shared with U.S. Route 64 (US-64) and US-169, which is maintained by the Oklahoma Department of Transportation (ODOT).
The first section of the Creek Turnpike, from US-75 in Jenks to US-64/US-169 in Tulsa, was first authorized in 1987, with construction beginning in 1989. The turnpike's construction was controversial; homeowners along the route of the highway formed a group called Tulsans Against Turnpikes to fight the highway in both the courtroom and the media. The highway was also challenged on environmental grounds, with impacts upon wetlands and endangered species being the chief concerns. Nevertheless, the highway opened to traffic in three sections, starting from the easternmost, over the course of the first half of 1992. (Full article...) - Interstate 182 (I-182) is an east–west auxiliary Interstate Highway in the U.S. state of Washington. It connects I-82 to the Tri-Cities region and 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 Washington 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 that would directly connect to the Tri-Cities area while allowing other traffic to bypass it. The project would also incorporate an existing proposal to build a bridge between Richland and Pasco at the site of a cable ferry that ran until 1931. (Full article...) - State Route 57 (SR 57), also known as the Orange Freeway for most of its length, is a north–south state highway in the Greater Los Angeles Area of the U.S. state of California. It connects the interchange of Interstate 5 (I-5) and SR 22 near downtown Orange, locally known as the Orange Crush, to the Glendora Curve interchange with the Foothill Freeway (I-210 and SR 210) in Glendora. The highway provides a route across several spurs of the Peninsular Ranges, linking the Los Angeles Basin with the Pomona Valley and San Gabriel Valley. SR 57 is also known colloquially as "the 57" to Southern California residents .
A predecessor to this road ran through Brea Canyon by the early 20th century and was added to the state highway system. The freeway was built in stages during the 1950s, one of which included the Brea Canyon Freeway; SR 57 was designated as part of the 1964 state highway renumbering. The final portion of the present-day Orange Freeway was not completed until the mid-1970s. The latest piece of SR 57 to be added was formerly part of I-210, after SR 210 was legislatively extended to San Bernardino in 1998. An unconstructed extension from Santa Ana south to Huntington Beach remains in the legal definition of SR 57, and has been studied as a toll road above the Santa Ana River. (Full article...) - Interstate 75 (I-75) is a part of the Interstate Highway System that runs from the Hialeah–Miami Lakes line to the Canadian border at Sault Ste. Marie, 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 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. (Full article...) - Interstate 90 (I-90) is an east–west transcontinental freeway and the longest Interstate Highway in the United States at 3,099.7 miles (4,988.5 km). It begins in Seattle, Washington, and travels through the Pacific Northwest, Mountain West, Great Plains, Midwest, and the Northeast, ending in Boston, Massachusetts. The highway serves 13 states and has 15 auxiliary routes, primarily in major cities such as Chicago, Cleveland, Buffalo, and Rochester.
I-90 begins at Washington State Route 519 in Seattle and crosses the Cascade Range in Washington and the Rocky Mountains in Montana. It then traverses the northern Great Plains and travels southeast through Wisconsin and the Chicago area by following the southern shore of Lake Michigan. The freeway continues across Indiana and follows the shore of Lake Erie through Ohio and Pennsylvania to Buffalo. I-90 travels across New York by roughly following the historic Erie Canal and traverses Massachusetts, reaching its eastern terminus at Massachusetts Route 1A near Logan International Airport in Boston.

SR 198 between San Lucas and Coalinga
State Route 198 (SR 198) is an east–west state highway in the U.S. state of California that runs from U.S. Route 101 (US 101) south of King City to Generals Highway in Sequoia National Park. It connects the California Central Coast to the mid–Central Valley through Hanford and Visalia, although the most developed portion is in the Central Valley itself. SR 198 intersects the major north–south routes in the Central Valley, including Interstate 5 (I-5), SR 33, and SR 99.
The highway that would become SR 198 was approved for construction in the 1910s through three bond issues, and was added to the state highway system in 1934. Parts of the highway were upgraded to freeway during the 1960s. Another portion was converted to an expressway in between Hanford and Visalia, and was completed in late 2012. (Full article...)- Maryland Route 54 (MD 54) and Delaware Route 54 (DE 54) are adjoining state highways in the U.S. states of Maryland and Delaware. Route 54 runs 41.84 mi (67.33 km) from MD 313 in Mardela Springs, Maryland, east to DE 1 in Fenwick Island, Delaware. In addition to two segments in which the highway is completely in Delaware and two segments in which the highway is completely in Maryland, Route 54 follows the Delaware/Maryland state line between the twin towns of Delmar, Maryland, and Delmar, Delaware, and the highway's intersection with MD 353 and DE 26. One section of the state line portion of Route 54 is maintained by the Delaware Department of Transportation (DelDOT) while three sections of the highway that follow the state line are maintained by the Maryland State Highway Administration (MDSHA).
Route 54 was first numbered in two segments in Wicomico County, Maryland, in the late 1930s. MD 467 was assigned to the segment around Mardela Springs while MD 455 was assigned to the state line road near Delmar. The Delaware portions of the highway remained unnumbered until the late 1960s, when DelDOT briefly assigned DE 32 to the highway along the southern edge of Sussex County before designating it DE 54. The Maryland State Roads Commission (now MDSHA) immediately reciprocated by designating its portions MD 54. Route 54 east of Selbyville has become an important route for seasonal beach traffic headed to and from Fenwick Island and Ocean City, with suburban development lining the road between DE 20 and the eastern terminus. DelDOT has signed DE 54 Alternate (DE 54 Alt.) as an alternate route to the beaches. Improvements have been made to the route west of Fenwick Island, including building a causeway to reduce flooding and adding a center left-turn lane. (Full article...) - State Route 20 (SR 20) is a state highway in the northern-central region of the U.S. state of California, running east–west north of Sacramento from the North Coast to the Sierra Nevada. Its west end is at SR 1 in Fort Bragg, from where it heads east past Clear Lake, Colusa, Yuba City, Marysville and Nevada City to I-80 near Emigrant Gap, where eastbound traffic can continue on other routes to Lake Tahoe or Nevada.
Portions of SR 20 are built near the routing of what was first a wagon road and later a turnpike in the late 19th century. This road was extended through the state highway system all the way to Ukiah in the early 20th century, and the missing link near Clear Lake was completed in 1932 before the official designation of this highway as SR 20 in 1934. There have been subsequent improvements to the road, such as the conversion of the Grass Valley portion of the route to freeway standards. (Full article...) - New York State Route 390 (NY 390) is a north–south freeway located along the western edge of the city of Rochester, New York, in the United States. The route, a northward continuation of Interstate 390 (I-390), extends for 8.00 miles (12.87 km) from I-490 in Gates to the Lake Ontario State Parkway in Greece, less than 1 mile (1.6 km) from the Lake Ontario shoreline. Between I-490 and NY 104, NY 390 makes up the north–south segment of the northwest quadrant of the Rochester Outer Loop, a series of freeways encircling Rochester. At NY 104, the Outer Loop departs NY 390 and follows NY 104 east into the city.
The freeway was constructed in stages from the 1960s to the 1980s, with the first segment—between I-490 and NY 31—opening to traffic c. 1963. At the time, it was part of NY 47, which followed the completed portions of the Outer Loop from Gates to Irondequoit. An extension of the freeway north to U.S. Route 104 (US 104; now NY 104) was opened to traffic in the early 1970s. NY 47 was eliminated in 1980, giving way to NY 390 from I-490 to NY 104. NY 390 was extended to its current length in the early 1980s. (Full article...) - North Carolina Highway 68 (NC 68) is a north–south state highway in North Carolina. It serves as a connector between Interstate 40 (I-40)/ U.S. Route 421 (US 421) and Piedmont Triad International Airport (via I-73). On its routing from Thomasville to Stokesdale, NC 68 passes through urban High Point, the western outskirts of Greensboro, and the town of Oak Ridge. (Full article...)
- Delaware Route 7 (DE 7) is a north–south highway in New Castle County, Delaware that connects U.S. Route 13 (US 13) and DE 72 in Wrangle Hill north to the Pennsylvania border near Hockessin, where the road continues into Pennsylvania as State Route 3013 (SR 3013), intersecting Pennsylvania Route 41 (PA 41) at an interchange. Between Wrangle Hill and Christiana, DE 7 runs parallel to the west of the DE 1 freeway through suburban areas, passing through Bear. DE 7 joins DE 1 next to the Christiana Mall and comes to an interchange with Interstate 95 (I-95), where DE 1 reaches its northern terminus, before the freeway ends at the DE 58 interchange. After the freeway segment, DE 7 continues north as an at-grade road concurrent with DE 4 through Stanton. From Stanton to the Pennsylvania border, DE 7 heads northwest through suburban areas, passing through Pike Creek.
What is now DE 7 was built as a state highway during the 1920s and 1930s. By 1936, the route was designated to run along its present alignment between US 13 near Red Lion and the Pennsylvania border. From the 1950s to the 1970s, DE 7 became a divided highway between Christiana and Milltown Road. With the construction of the DE 1 freeway in the 1990s, DE 7 was shifted to a portion of the freeway near the Christiana Mall. The route was also extended south to an intersection with US 13 and DE 72 as a result of the relocation of US 13 onto a portion of the freeway. The road also became a divided highway between Milltown Road and DE 72 in the 1990s. In 1999, an interchange was built at DE 58 as a result of a northward extension of the freeway along DE 7. The interchange with I-95 was reconstructed to include flyover ramps in 2013.

The highway was first established in 1961 and expanded over the following two years. K-232 is designated by the Kansas Department of Transportation as the Post Rock Scenic Byway. The scenic byway derives its name from the abundant Fencepost limestone, also known as the Post Rock, which early settlers used as fence posts and in other construction in place of wood. The route was designated as a scenic byway both for the natural beauty of the area and unique towns located each end of the highway. Annual average daily traffic on the highway ranges from 238 to 340, and the entire route is paved with partial design bituminous pavement. (Full article...)
- K-33 is an approximately 10.4-mile-long (16.7 km) north–south state highway in the U.S. state of Kansas. K-33's southern terminus is at K-68 in rural Franklin County east of Ottawa and the northern terminus is at U.S. Route 56 (US-56) in Douglas County, east of Baldwin City and southwest of Kansas City. K-33 provides an important link between US-56 and K-68 to Interstate 35 (I-35) and US-50 in Wellsville. K-33 is a two-lane rural highway for most of its length, except for the section within Wellsville.
Before state highways were numbered in Kansas, there were auto trails. The majority of K-33's route closely follows the former New Santa Fe Trail, King of Trails and Ozark Trail. K-33 was first designated as a state highway in 1926. At this point the highway began near Waverly and ran northeastward to Ottawa, then east to the Missouri border. By the next year, K-33 had been realigned to turn north, just west of Ottawa, then passing through Wellsville to Edgerton. In 1934, the northern terminus of K-33 had been realigned to the west of Edgerton. Two years later, K-33's southern terminus had been truncated to Ottawa. In 1969, the overlap with K-68 had been eliminated and K-33 was truncated to its current southern terminus. (Full article...) - Delaware Route 23 (DE 23) is a 15.63-mile-long (25.15 km) state highway in Sussex County, Delaware. Its southern terminus is at Massey's Landing in Long Neck, near the confluence of Rehoboth Bay and Indian River Bay and its northern terminus is at the Five Points intersection in Nassau, where it ends at U.S. Route 9 (US 9)/DE 404. From the southern terminus, the route runs west through residential areas of Long Neck before heading north through rural areas with some development. DE 23 is concurrent with DE 5 between the DE 24 intersection in Long Neck and Fairmount. It is also concurrent with DE 24 Alternate (DE 24 Alt.) between Hollymount and the DE 1D intersection in Five Points. The road was designated as part of DE 22 south of Fairmount for a short time in the 1930s, with DE 5 designated along the stretch between DE 24 and Fairmount by 1938; the remainder of the road was unnumbered. The road was fully paved by 1970. The DE 23 designation was assigned by 1994. (Full article...)
- Route 47 is a state highway in the southern part of New Jersey. It runs 75.20 miles (121.02 km) from Atlantic Avenue in Wildwood, Cape May County, north to U.S. Route 130 (US 130) in Brooklawn, Camden County. It is also referred to as Delsea Drive, as it connects the Delaware River near Brooklawn to the Atlantic Ocean (the sea) in Wildwood. This name was assigned by the New Jersey Legislature in 1933. The route runs through rural areas of Cape May and southern Cumberland counties as a two-lane road. Traffic jams along this portion of Route 47 are commonplace in the summer vacation season and can stretch for miles due to the missing southern section of Route 55, where all Jersey Shore-bound traffic enters the small two-lane road. North of here, the route runs through the cities of Millville and Vineland before entering Gloucester County, where it passes through more rural areas as well as Clayton and Glassboro. Past Glassboro, it heads through suburban areas in Washington and Deptford townships before running through Westville and Brooklawn. Route 47 is the longest signed state route in New Jersey.
What is now Route 47 was originally designated as part of pre-1927 Route 15 between Rio Grande in 1917 and as a branch of pre-1927 Route 20 between Millville and Westville in 1923. In 1927, Route 47 was designated to run from Tuckahoe to Brooklawn, following current Route 49 south of Millville. Meanwhile, current Route 47 was a part of Route 49 between South Dennis and Millville and Route S49 between Rio Grande and South Dennis. The latter was extended to Wildwood in 1938. Route 47 and Route 49 were shifted onto their current alignments south of Millville in 1953. Since then, Route 47 has seen a few improvements and modifications including realignment in Millville and the reconstruction of the intersection with Route 83 in Dennis Township.

- Route 162 is a state highway in the Missouri Bootheel. Its western terminus is at Route 25 in Clarkton, Dunklin County, and the route travels eastward to nearby towns of Gideon and Portageville, where it intersects U.S. Route 61 (US 61) and Interstate 55 (I-55).

- New York State Route 391 (NY 391) is a short state highway in Erie County, New York, in the United States. The route is signed as north–south; however, it follows more of a southeast–northwest alignment between NY 277 in the hamlet of North Boston and U.S. Route 62 (US 62) in the village of Hamburg. NY 391 meets the Southern Expressway (US 219) just north of North Boston. Both ends of NY 391 are located in residential areas; however, the middle section of the route passes through more rural areas of the towns of Boston and Hamburg.
The routing of NY 391 has been part of several routes over the years, beginning with NY 62 in 1930. NY 62 was mostly renumbered to NY 75 c. 1932, and all of NY 75 south of Hamburg became concurrent to US 219 when it was extended into New York c. 1935. NY 75 was cut back to Hamburg by 1940, leaving just US 219 on modern NY 391. US 219 was realigned north of North Boston in the early 1970s to follow other routes north to meet the first completed piece of the Southern Expressway near Orchard Park. NY 391 was assigned to US 219's former routing into Hamburg at this time. The route originally ended two blocks to the west at the junction of NY 75 and US 62; however, this extension was eliminated c. 2004. (Full article...)
