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).
More about the Interstate Highway System...
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 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...)
New York State Route 174 (NY 174) is a state highwayinOnondaga County, located in Central New York, in the United States. The highway is 16.7 miles (26.9 km) long and passes through mostly rural regions. Route 174 begins at an intersection with NY 41inBorodino, a hamlet of Spafford. It heads generally northward for most of its length, except for short distances in the villages of Marcellus and Camillus. The route ends at a junction with NY 5 west of Camillus, at the west end of the Route 5 Camillus bypass. Route 174 is located along a large mapped sedimentary bedrock unit, known as the Marcellus Formation. The formation is named for an outcrop found near the town of Marcellus, New York, during a geological survey in 1839.
The road was first constructed in the early 19th century following the path of Nine Mile Creek, which connected several early settlements in Central New York. The northern half of the route, between the villages of Marcellus and Camillus, was later improved as a plank road in 1855 by a private corporation that collected tolls from travelers on the road. The state took over the maintenance of the road by the beginning of the 20th century. The former plank road and an extension south to Otisco Lake and southwest to Skaneateles Lake was first designated as Route 174 in the 1930 state highway renumbering. Since then, several minor realignments have been made in the areas of the villages of Marcellus and Camillus to accommodate newly built bypasses. (Full article...)
US Highway 2 (US 2) is a component of the United States Numbered Highway System that connects Everett, Washington, to the Upper Peninsula (UP) of the US state of Michigan, with a separate segment that runs from Rouses Point, New York, to Houlton, Maine. In Michigan, the highway runs through the UP in two segments as a part of the state trunkline highway system, entering the state at Ironwood and ending at St. Ignace; in between, US 2 briefly traverses the state of Wisconsin. As one of the major transportation arteries in the UP, US 2 is a major conduit for traffic through the state and neighboring northern Midwest states. Two sections of the roadway are included as part of the Great Lakes Circle Tours, and other segments are listed as state-designated Pure Michigan Byways. There are several memorial highway designations and historic bridges along US 2 that date to the 1910s and 1920s. The highway runs through rural sections of the UP, passing through two national and two state forests in the process.
The route of what became US 2 was used as part of two Indian trails before European settlers came to the UP, and as part of the Michigan segments of the Theodore Roosevelt International Highway and the King's International Highway auto trails in the early 20th century. The state later included these trails as part of M‑12 when the first state highway trunklines were designated in 1919. Most of M‑12 was redesignated as part of US 2 when the US Highway System was created on November 11, 1926. Since the 1930s, several changes have reshaped the highway's routing through the UP. One such alteration eventually created a business loop that connected across the state line with Hurley, Wisconsin, and others pushed an originally inland routing of US 2 closer to the Lake Michigan shoreline. With the creation of the Interstate Highway System, part of US 2 was rerouted to coincide with the new Interstate 75 (I‑75), though in the 1980s, the U.S. Highway was truncated and removed from the I‑75 freeway, resulting in today's basic form.

Interstate 80 Business (I-80 Bus) is an unofficial business loopofInterstate 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 CaliforniatoNew Jersey via Nevada and Utah. A portion of the Nevada segment is concurrent with US 93 Alternate (US 93 Alt), and the entire portion in Utah is coterminous with Utah 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 Nevada State Route 224 (SR 224) in Nevada. (Full article...)
New York State Route 311 (NY 311) is a state highway located entirely within Putnam County, New York, in the United States. It begins at NY 52 in Lake Carmel, and intersects Interstate 84 (I-84) shortly thereafter. It crosses NY 164 and NY 292 as it heads into the northeastern part of the county, finally curving east to reach its northern terminus at NY 22 just south of the Dutchess County line. The route passes several historical sites.
Part of modern-day Route 311 was originally the Philipstown Turnpike, a road built in 1815 to overcome a lack of transportation when the Hudson River froze during the winter months. The turnpike was a large business center for the county, though it was abandoned due to insufficient tolls to maintain it. Another section was constructed in the early 1900s, from the Patterson Baptist Church near the modern-day intersection of Route 311 and Route 164 to the Village of Patterson, by a group of Italian immigrants.

US Highway 45 (US 45) is a part of the United States Numbered Highway System that runs from Mobile, Alabama, to the Upper Peninsula (UP) of the state of Michigan. The highway forms a part of the state trunkline highway system that is maintained by the Michigan Department of Transportation (MDOT). It enters the state from Wisconsin south of Watersmeet, ending at an intersection with Ontonagon Street in Ontonagon. In between, the roadway crosses the UP running for approximately 54+3⁄4 miles (88.1 km) through the Ottawa National Forest and parallel to the Ontonagon River.
The highway dates back to the 1930s in Michigan. At the time it was extended into the state, it replaced sections of M-26 and M-35. An eight-mile (13 km) segment was significantly reconstructed in the late 1950s, and an alignment change in the 1970s moved the routing of US 45 near Rockland before it was reversed soon afterwards. A segment of roadway that formerly carried US 45 is the site of the Paulding Light, a local phenomenon whose origins were scientifically described in 2010. (Full article...)
New York State Route 74 (NY 74) and Vermont Route 74 (VT 74) are state highways in the northeastern United States, connected by one of the last remaining cable ferries in North America. Together they extend for 34 miles (55 km) through Essex County, New York, and Addison County, Vermont. NY 74 begins at exit 28 off Interstate 87 (I-87) in the hamlet of Severance in the Adirondack Mountains region of the northern part of New York State. It extends 20.44 miles (32.89 km) to the western shore of Lake ChamplaininTiconderoga. There, the seasonal Fort Ticonderoga–Larrabees Point Ferry carries cars across the state border into Vermont, where VT 74 starts at the lake's eastern shore and terminates 13.26 miles (21.34 km) later at a junction with VT 30 in the town of Cornwall.
The ferry connecting the two highways, predating both NY 74 and VT 74, began operation in 1759 on an informal basis. The ferry operation was formalized at the close of the 18th century and upgraded to a cable system in 1946. (Full article...)
Interstate 196 (I-196) is an auxiliary Interstate Highway that runs for 80.6 miles (129.7 km) in the US state of Michigan. It is a state trunkline highway that links Benton Harbor, South Haven, Holland, and Grand Rapids. In Kent, Ottawa, and Allegan counties, I-196 is known as the Gerald R. Ford Freeway, or simply the Ford Freeway, after President Gerald Ford, who was raised in Grand Rapids and served Michigan in the House of Representatives for 25 years. This name generally refers only to the section between Holland and Grand Rapids. I-196 changes direction; it is signed as a north–south highway from its southern terminus to the junction with US Highway 31 (US 31) just south of Holland, and as an east–west trunkline from this point to its eastern terminus at an interchange with I-96, its parent highway. There are three business routes related to the main freeway. There are two business loops (BL I-196) and one business spur (BS I-196) that serve South Haven, Holland and the Grand Rapids areas. Another business spur for Muskegon had been designated relative to the I-196 number.
The freeway numbered I-196 is the second in the state to bear the number. Originally to be numbered as part of the I-94 corridor in the state, the Benton Harbor–Grand Rapids freeway was given the I-96 number in the 1950s while another Interstate between Muskegon and Grand Rapids was numbered I-196. That I-196 was built in the late 1950s and completed in the early 1960s. The first segment of the current I-196 was opened as I-96 near Benton Harbor in 1962. Michigan officials requested a change in 1963 which reversed the two numbers, and the subsequent segments of freeway opened northward to Holland and from Grand Rapids westward under the current number. The gap between Holland and Grandville was filled in the 1970s, and a section of freeway that runs through downtown Grand Rapids was rebuilt as a wider freeway in 2010. (Full article...)
M-185 is a state trunkline highway in the U.S. state of Michigan that circles Mackinac Island, a popular tourist destination on the Lake Huron side of the Straits of Mackinac, along the island's shoreline. A narrow paved road of 8.004 miles (12.881 km), it offers scenic views of the straits that divide the Upper and the Lower peninsulas of Michigan and Lakes Huron and Michigan. It has no connection to any other Michigan state trunkline highways—as it is on an island—and is accessible only by passenger ferry. The City of Mackinac Island, which shares jurisdiction over the island with the Mackinac Island State Park Commission (MISPC), calls the highway Main Street within the built-up area on the island's southeast quadrant, and Lake Shore Road elsewhere. M-185 passes by several important sites within Mackinac Island State Park, including Fort Mackinac, Arch Rock, British Landing, and Devil's Kitchen. Lake Shore Road carries the highway next to the Lake Huron shoreline, running between the water's edge and woodlands outside the downtown area.
According to the Michigan Department of Transportation (MDOT), M-185 is "the only state highway in the nation where motor vehicles are banned". Traffic on it is by foot, on horse, by horse-drawn vehicle, or by bicycle. Restrictions on automobiles date back to 1898, and since the ban, only a few vehicles have been permitted on the island other than the city's emergency vehicles. The highway was built during the first decade of the 20th century by the state and designated as a state highway in 1933. The highway was paved in 1960, and portions were rebuilt to deal with shoreline erosion in the 1980s. Until an accident in 2005, it was the only state highway without any automobile accidents.

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-496orCL 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...)
Interstate 15 (I-15) is an Interstate Highway, running from San Diego, California, United States, to the Canada–US border, through Mohave County in northwest Arizona. Despite being isolated from the rest of Arizona, in the remote Arizona Strip, and short in length at 29.43 miles (47.36 km), it remains notable for its scenic passage through the Virgin River Gorge. The highway heads in a northeasterly direction from the Nevada border northeast of Mesquite, Nevada, to the Utah border southwest of St. George, Utah.
The south portion of I-15's route was built close to the alignment of the old U.S. Route 91 (US 91), but the northern section, through the Virgin River Gorge, was built along roadless terrain. The southern section of the highway was complete and open in the early 1960s, but the gorge section was inaccessible until 1973. When it opened, the Virgin River Gorge passage was the most expensive section of rural Interstate per mile. (Full article...)
US Highway 31 (US 31) is a part of the United States Numbered Highway System that runs from Alabama to the Lower Peninsula of the US state of Michigan. In Michigan, it is a state trunkline highway that runs from the Indiana–Michigan state line at Bertrand Township north to its terminus at Interstate 75 (I-75) south of Mackinaw City. Along its 355.2-mile-long (571.6 km) route, US 31 follows the Michigan section of the St. Joseph Valley Parkway as well as other freeways and divided highways northward to Ludington. North of there, the trunkline is a rural undivided highway through the Northern Michigan tourist destinations of Traverse City and Petoskey before terminating south of Mackinaw City. Along its route, US 31 has been dedicated in memory of a few different organizations, and sections of it carry the Lake Michigan Circle Tour (LMCT) moniker. Four bridges used by the highway have been recognized for their historic character as well.
The first highways along the route of the modern US 31 corridor were the West Michigan Pike, an auto trail from 1913, and later a pair of state trunklines (the original M-11 and M-58) in 1919. These state highways were redesignated US 31 on November 11, 1926, when the US Highway System was approved. Since then, the highway has been realigned in places. The highway crossed the Straits of Mackinac by ferry for about a decade in the 1920s and 1930s before the Mackinac Bridge was built, connecting to US 2 north of St. Ignace. Later, sections were converted into freeways starting in the 1950s. These segments opened through the subsequent decades with the last one opening in 2022. Future plans by the Michigan Department of Transportation (MDOT) include a bypass of Grand Haven. (Full article...)
New York State Route 308 (NY 308) is a short state highway, 6.19 miles (9.96 km) in length, located entirely in northern Dutchess County, in the U.S. stateofNew York. It is a major collector road through a mostly rural area, serving primarily as a shortcut for traffic from the two main north–south routes in the area, U.S. Route 9 (US 9) and NY 9G, to get to NY 199 and the Taconic State Parkway. The western end of NY 308 is located within Rhinebeck's historic district, a 2.6-square-mile (6.7 km2) historic district comprising 272 historical structures. The highway passes near the Dutchess County Fairgrounds, several historical landmarks, and briefly parallels the Landsman Kill.
Artifacts found near Lake Sepasco, near NY 308's eastern terminus at Rock City, date to about 1685, when the Sepasco Native Americans built the Sepasco Trail from the Hudson River, eastward through modern-day Rhinebeck (then Sepasco or Sepascoot) to the lake, following roughly NY 308 and its side roads. The trail remained until 1802, when part of the Ulster and Delaware Turnpike—also known as the Salisbury Turnpike—was chartered over the trail and extended from Salisbury, Connecticut, to the Susquehanna River at or near the Town of Jericho (now Bainbridge).

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-10inRiverside 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 MountainstoJulian. 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 CountyofSan 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 68 (I-68) is a 113.15-mile (182.10 km) Interstate Highway in the U.S. states of West Virginia and Maryland, connecting I-79inMorgantown, West Virginia, east to I-70inHancock, Maryland. I-68 is also Corridor E of the Appalachian Development Highway System (ADHS). From 1965 until the freeway's construction was completed in 1991, it was designated as U.S. Route 48 (US 48). In Maryland, the highway is known as the National Freeway, an homage to the historic National Road, which I-68 parallels between Keysers Ridge and Hancock. The freeway mainly spans rural areas and crosses numerous mountain ridges along its route. A road cut at Sideling Hill exposed geological features of the mountain and has become a tourist attraction.
US 219 and US 220 overlap I-68 in Garrett County and Cumberland, respectively, and US 40 overlaps with the freeway from Keysers Ridge to the eastern end of the freeway at Hancock. (Full article...)

Interstate 140 (I-140) and North Carolina Highway 140 (NC 140) is a 25.4-mile (40.9 km) auxiliary Interstate Highway and state highway in the U.S. stateofNorth Carolina. Officially designated the John Jay Burney Jr. Freeway, it serves as a bypass of Wilmington. The western terminus of the highway is at U.S. Route 17 (US 17) near Winnabow. It heads north in western Leland before turning to the east north of an interchange with U.S. Route 74 (US 74)/U.S. Route 76 (US 76). I-140 crosses the Cape Fear River north of Navassa and the Northeast Cape Fear River northwest of Wrightsboro. I-140 ends at Interstate 40 (I-40), and the route number changes to NC 140. NC 140 continues to the east, ending at US 17 in Kirkland.
The need for a bypass north of Wilmington was identified by the North Carolina Department of Transportation (NCDOT) in 1972. However, the first contract for construction was not awarded until 2000. In August 2005, the first segment of I-140 between I-40 and North Carolina Highway 133 (NC 133) opened. This was followed by a westward extension to U.S. Route 421 (US 421) and an eastward extension to US 17 in June 2006. US 17 was routed along the entirety of the freeway between Kirkland and US 421, running concurrently with I-140. Construction on the western segment between Winnabow and US 74/US 76 began in March 2010 and was opened in September 2014. This segment was temporarily designated as NC 140 as it lacked connection with I-140 to the east. The final segment between US 74/US 76 and US 421 began construction in 2014 and was completed in 2017. I-140 was routed along the entirety of the freeway west of I-40. Additionally, US 17 was removed from its concurrency with I-140, being rerouted through Wilmington in 2017. The remaining section between I-40 and Kirkland was subsequently renumbered as NC 140.

Route 440 is a state highwayinNew Jersey, United States. It comprises two segments, a 5.15-mile (8.29 km) freewayinMiddlesex County linking Interstate 287 (I-287) and the New Jersey Turnpike (I-95), in Edison to the Outerbridge CrossinginPerth Amboy and an 8.18-mile (13.16 km) four-lane divided highwayinHudson County running from the Bayonne BridgeinBayonnetoU.S. Route 1/9 Truck (US 1-9 Truck) in Jersey City. These two segments are connected by New York State Route 440 (NY 440), which runs across Staten Island. The freeway portion in Middlesex County is six lanes wide and interchanges with the Garden State Parkway and US 9inWoodbridge.
What is now Route 440 was designated as two different routes in 1927: the Middlesex County portion between Route 4 (now Route 35) and the proposed Outerbridge Crossing was designated Route S4 (a spur of Route 4) while the Hudson County portion was designated as a part of Route 1. In 1953, Route 440 replaced Route S4 as well as Route 1 south of Communipaw Avenue; the number was chosen to match NY 440. A freeway was built for the route in Middlesex County between 1967 and finished in 1972. A freeway was also proposed for the route in Hudson County to fill in the gap between the Bayonne Bridge and 63rd Street; however, it was never built. In 2001, Route 440 replaced Route 169 along the Bayonne waterfront. (Full article...)
M-52 is a north–south state trunkline highway in the US state of Michigan. The southern terminus is on the Ohio border, where it continues as State Route 109 (SR 109). The highway passes through communities like Adrian, where it intersects US Highway 223 (US 223), Chelsea and Webberville along its 127.3-mile-long (204.9 km) course. It crosses some major rivers, including the River Raisin and the Shiawassee. The section of the highway between M-50 and Manchester was built as a limited-access highway. M-52's northern terminus is at M-46, nine miles (14 km) west of Saginaw.
Adrian previously converted their downtown streets to one-way traffic between 1950 and 1973. The traffic pattern created an unusual arrangement in the routings of the two state highways downtown. Southbound M-52 followed Winter Street, which also carried both eastbound and westbound directions of the US 223 business loop. These streets carried both highways around the downtown business district in this arrangement until November 2009. (Full article...)
M-150 is a state trunkline highway in the US state of Michigan that runs through Rochester Hills and Rochester. It is more commonly known as Rochester Road and runs from a southern terminus at the M-59 freeway north through downtown Rochester to a northern terminus at Tienken Road. M-150 has been a state trunkline since around 1930, and within a few years of its commissioning, it was extended south through Royal Oak and north into rural Oakland County. After changes in the 1960s, the highway terminated in TroyatInterstate 75 (I-75) on the southern end and Tienken Road on the north. Since 1987, it has ended at M-59. (Full article...)
New York State Route 173 (NY 173) is a state highway located in the Syracuse area of central New York in the United States. It takes a slightly bow-shaped route from NY 31 in the town of Van BurentoNY 5inChittenango, gently curving to the south of Downtown Syracuse in the center of its 30.59-mile (49.23 km) routing. Even so, NY 173 briefly enters the Syracuse city limits near where it intersects U.S. Route 11 (US 11). NY 173 passes through several suburbs of Syracuse, including Camillus, where it first meets NY 5, and Manlius, where it has a short overlap with NY 92.
NY 173 was assigned as part of the 1930 renumbering of state highways in New York to its modern alignment. The route itself has not been altered since; however, the portion of the route from Onondaga to Manlius became part of NY 20N c. 1938 and a small section of the route within Manlius was included in NY 20SY when that highway was assigned in the early 1950s. Both designations were removed in 1961. All of NY 173 east of Onondaga was originally part of the Seneca Turnpike. (Full article...)
M-130 was the designation of a former state trunkline highway in the southeastern corner of the US state of Michigan. It ran from a junction with US Highway 23/M-50 (US 23/M-50) northward across the River Raisin and then turned southeasterly along North Custer Road on the north side of the river to Monroe. The highway designation was commissioned in 1929 and used until 1955. M-130 had a spur route that was created in 1938 and lasted until the main highway was removed from the state highway system. Both highways are now under local control. (Full article...)
State Route 666 (SR 666) is a 14.17-mile (22.80 km) state route that runs between Zanesville and Dresden in the US state of Ohio. Most of the route is a rural two-lane highway and passes through both woodland and farmland. For much of its path, SR 666 runs generally parallel to the east of the Muskingum River. The highway was first signed in 1937 on the same alignment as today. The whole highway was paved by 1955. (Full article...)
Pennsylvania Route 997 (PA 997) is a 49.0-mile (78.9 km) route that is located in Franklin and Cumberland counties in central Pennsylvania in the United States. This route runs from the Maryland state line south of Waynesboro, where the road continues into that state as Maryland Route 64 (MD 64), north to PA 233 in the Upper Mifflin Township community of McCrea.
PA 997 heads north from the state line through agricultural areas in the Cumberland Valley and passes through Waynesboro, where it intersects PA 16, and Mont Alto, where it intersects the south end of PA 233, before coming to U.S. Route 30 (US 30) in Greenwood. From here, the route turns northwest and comes to a junction with Interstate 81 (I-81) and PA 696 near Scotland and US 11inGreen Village. (Full article...)
State Highway 9, abbreviated as SH-9, OK-9, or simply Highway 9, is a major east–west highway in the U.S. state of Oklahoma. Spanning across the central part of the state, SH-9 begins at the Texas state line west of Vinson, Oklahoma, and ends at the Arkansas state line near Fort Smith, Arkansas. State Highway 9 is a major highway around the Norman area. At 348.1 miles (560.2 km), SH-9 is Oklahoma's second-longest state highway (second to State Highway 3). (Full article...)

M-13 is a 73.339-mile (118.028 km) north–south state trunkline highway that runs through the Saginaw Bay region of the US state of Michigan. It runs from Interstate 69 (I-69) south of LennontoUS Highway 23 (US 23) near Standish. The southern section of the trunkline runs along a pair of county lines in a rural area dominated by farm fields. The highway directly connects the downtown areas of both Saginaw and Bay City. North of the latter city, the Lake Huron Circle Tour follows M-13 along the Saginaw Bay.
The original 1919 version of M-13 ran along the west side of the state, roughly replaced by what is now US 131 in 1926. The current highway was first designated by 1932 with the M-13 moniker. After a series of extensions in the 1930s, the highway ran from Lennon to Saginaw. Another set of expansions in the 1960s added roadways that previously carried US 23 all the way north to the Standish area. A related section of highway is numbered Connector M-13, a connector route that was once part of US 23 in the Kawkawlin area. (Full article...)
Route 33 is a state highway in the central part of the US state of New Jersey. The highway extends 42.03 miles (67.64 km), from an interchange with U.S. Route 1 (US 1) in Trenton, Mercer County, east to an intersection with Route 71inNeptune, Monmouth County. Route 33 is a major route through central New Jersey, as it runs from the greater state capital area in the Delaware Valley region, through a mixture of farmland, housing, and commercial developments in the lower Raritan Valley region, en route to the greater Asbury Park area on the Jersey Shore. The route traverses through historic towns such as Hightstown, Monroe, Manalapan, Freehold, and Tinton Falls. There are several intersections on Route 33 with future developments.
Route 33 begins in Trenton as a two-lane residential street. It passes through central Mercer County, joining northbound US 130 in Robbinsville. It leaves the U.S. highway in East Windsor and becomes a local town road into the borough of Hightstown. It turns east again as it passes the east end of the Hightstown Bypass, where it becomes an arterial road with four lanes as it makes its way through Monmouth County toward the shore. Around the greater "Freeholds area", it becomes a freeway. It then crosses the Garden State Parkway's Exit 100 in Tinton Falls and Route 18 in Neptune. Here, it is locally known as Corlies Avenue. Route 33 ends at Route 71 in Neptune. It has two concurrencies along the route, one with Route 34 and the second with US 130. It roughly parallels Interstate 195, located further to the south.

Guam Highway 1 (GH-1), also known as Marine Corps Drive, is one of the primary automobile routes in the United States territory of Guam. It runs in a southwest-to-northeast direction, from the main gate of Naval Base Guam in the southwestern villageofSanta Rita in a northeasterly direction to the main gate of Andersen Air Force Base in the village of Yigo. It passes through Guam's capital, Hagåtña, as well as intersecting other territorial highways. The highway runs through tropical forest, urbanized commercial areas, and residential neighborhoods. The US military upgraded and extended the road starting in 1941. Construction ceased with the Japanese invasion in December 1941 and resumed after the Second Battle of Guam in 1944. The highway was formally dedicated to the U.S. Marine Corps by the governor in 2004. (Full article...)
New York State Route 210 (NY 210) is a state highwayinOrange County, New York, in the United States. It runs north from the New Jersey state line—where it continues south as Passaic County Route 511 (CR 511)—along the west shore of Greenwood Lake to the eponymous village of Greenwood Lake, where it ends at a junction with NY 17A. It was once much longer, as it originally extended east along NY 17A and CR 106 in Orange and Rockland counties to Stony Point when it was assigned as part of the 1930 renumbering of state highways in New York. The route was truncated to its current length in 1982. Prior to becoming NY 210 in 1930, the road alongside Greenwood Lake was part of NY 55, a route connecting New Jersey to Goshen, in the 1920s.

M-168 was one of the shortest state trunkline highways in the US state of Michigan, extending just under a mile (1.6 km) from a junction with M-22 in downtown Elberta to the former Ann Arbor Railroad ferry docks. It followed the south shore of Lake Betsie (formed by the Betsie River before flowing into Lake Michigan). The highway was commissioned in 1931 and served as a connection to the car ferries until 1984. The road was reconstructed by the Michigan Department of Transportation (MDOT) in preparation to transfer it to village control. That transfer happened on April 24, 2012, and now the former highway is a village street. (Full article...)
State Route 37 (SR 37) is a state highway in the U.S. stateofCalifornia that runs 21 miles (34 km) along the northern shore of San Pablo Bay. It serves as a vital connection in the North Bay region of the San Francisco Bay Area, running from U.S. Route 101inNovato, through northeastern Marin County, and the southern tips of both Sonoma and Solano Counties to Interstate 80inVallejo. Sonoma Raceway and Six Flags Discovery Kingdom are accessible from Highway 37.
The section of Highway 37 between Sears Point and Vallejo was the Sears Point Toll Road, a toll road managed by Golden Gate Ferry, before it was purchased by the State in 1938. The highway has been proposed to be built to freeway standards since the early 1950s. However, the proposal was met with many economic and environmental obstacles, making the task all but impossible for much of the route. The route is plagued by flooding which can be exacerbated by levee breaks near Vallejo. Most of the highway crosses a marsh that is home to endangered salt marsh harvest mice. A section of highway was once known as "Blood Alley" for its high rate of fatal accidents. A concrete barrier built in the 1990s eliminated those fatal head-on collisions. By 2022, there have been proposals to reinstate tolls between Sears Point and Vallejo to help pay for flooding and other improvements. (Full article...)
