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.

Image 1The 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...) -
Image 2Interstate 15 (I-15) is an Interstate Highway, running from San Diego, California, United States, to the Canadian border, through Mohave County in northwestern 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 state line, southwest of St. George, Utah.
The southern 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...) -
Image 3M-553 is a north–south state trunkline highway in the Upper Peninsula (UP) of the US state of Michigan. It connects M-35 near Gwinn with the Marquette Bypass, an expressway carrying US Highway 41 (US 41) and M-28 in Marquette. M-553 connects Marquette with Marquette Sawyer Regional Airport at the unincorporated community of K.I. Sawyer, the former site of a US Air Force base, in the Sands Plains area of Marquette County. The intersection with County Road 480 (CR 480) in Sands Township, known locally as the Crossroads, is the site of several businesses. North of this location, M-553 runs through some hilly terrain around a local ski hill.
The trunkline was originally County Road 553 (CR 553) in Marquette County. CR 553 dates back to the 1930s, was fully paved in the 1940s, and a segment of the roadway was relocated in the 1950s. During the early 1990s, the City of Marquette extended one of their streets, McClellan Avenue, southward to connect to CR 553. The county road was transferred from the Marquette County Road Commission (MCRC) to the jurisdiction of the Michigan Department of Transportation (MDOT) on October 1, 1998. MDOT assigned most of the former county road the M-553 designation after the transfer was complete. One section that was less than a mile (about 1.4 km) was given the M-554 designation. This related trunkline was unsigned by the state with only city street signs to indicate its existence. In 2005, control of various roadways was exchanged between the City of Marquette and MDOT, and M-553 was extended through the city. At the same time, M-554 was turned over to the city's jurisdiction.

Image 4New York State Route 28 (NY 28) is a state highway extending for 281.69 miles (453.34 km) in the shape of a "C" between the Hudson Valley city of Kingston and southern Warren County in the U.S. state of New York. Along the way, it intersects several major routes, including Interstate 88 (I-88), U.S. Route 20 (US 20), and the New York State Thruway twice. The southern terminus of NY 28 is at NY 32 in Kingston and the northern terminus is at US 9 in Warrensburg. In Kingston, NY 28 is co-designated as Interstate 587 from its southern terminus at NY 32 to the roundabout linking it to the Thruway (I-87).
NY 28 was originally assigned in 1924, to an alignment extending from Colliersville in the south to Utica in the north via Ilion. From Colliersville to Cooperstown, the highway followed its current routing (excluding minor realignments); north of Cooperstown, NY 28 was routed along several state highways that now have other designations. The route was extended south to Kingston and north to Warrensburg as part of the 1930 renumbering of state highways in New York. At the same time, NY 28 was realigned between Cooperstown and Mohawk to follow its modern routing. Other than minor realignments in Kingston, Oneonta, Herkimer, and Oneida County, NY 28 has remained the same to this day. (Full article...) -
Image 5New 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. state of New 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).

Image 6US Highway 23 (US 23) is a north–south United States Numbered Highway that runs from Jacksonville, Florida, to Mackinaw City, Michigan. In the state of Michigan, it is a major, 362-mile-long (583 km), north–south state trunkline highway that runs through the Lower Peninsula. The trunkline is a freeway from the Michigan–Ohio state line near Lambertville to the city of Standish, and it follows the Lake Huron shoreline from there to its northern terminus. Serving the cities of Ann Arbor and Flint, US 23 acts as a freeway bypass of the Metro Detroit area. Overall, the highway runs through rural areas of the state dominated by farm fields or woodlands; some segments are urban in character in the Ann Arbor, Flint and Tri-Cities areas. The section from Flint north to Standish also carries Interstate 75 (I-75) along a concurrency that includes a segment that carries almost 70,000 vehicles on a daily basis.
The first transportation routes along what is now US 23 in the state were sections of two Indian trails. In the early 20th century, four different auto trail names were applied to roads now a part of the highway. These roads were included as part of two state highways in the initial state highway system in 1919. When the United States Numbered Highway System was first designated on November 11, 1926, the new US 23 replaced the other designations along its route. Since creation, the road has been moved and realigned several times. Through the 1930s and 1940s, the lakeshore routing was created to replace a path that ran further inland through the northern portion of the state. Starting in the early 1950s, various sections in the southeastern and central areas of the Lower Peninsula were upgraded to freeways, bypassing several major cities in the area. These improvements were completed by the end of the 1960s. Since then a new crossing of the Saginaw River at Zilwaukee was built to replace a drawbridge that carried the I-75/US 23 freeway over a shipping channel. (Full article...) -
Image 7State Route 94 (SR 94) is a state highway in the U.S. state of California that is 63.324 miles (101.910 km) long. The western portion, known as the Martin Luther King Jr. Freeway, begins at Interstate 5 (I-5) in downtown San Diego and continues to the end of the freeway portion past SR 125 in Spring Valley. The non-freeway segment of SR 94 that continues east through the mountains to I-8 near Boulevard is known as Campo Road.
The Campo road served as a wagon road providing access to eastern San Diego County as well as Imperial County. The road was added to the state highway system in 1933, and signs for Route 94 were posted along local roads later that decade. Efforts to convert the western half of the route to a freeway got underway in the 1950s, and the freeway was complete by 1962 west of the road that became SR 125. Construction continued east to Avocado Road over the next few years. Various proposals for widening the highway have come from the California Department of Transportation (Caltrans), but local opposition resulted in the delay or cancellation of many of these proposals.

Image 8Interstate 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.

Image 9State Route 128 (SR-128) is a 44.564-mile-long (71.719 km) state highway in the U.S. state of Utah. The entire length of the highway has been designated the Upper Colorado River Scenic Byway, as part of the Utah Scenic Byways program. This road also forms part of the Dinosaur Diamond Prehistoric Highway, a National Scenic Byway. Residents of Moab frequently refer to SR-128 as "the river road", after the Colorado River, which the highway follows.
The highway was originally constructed to connect rural cities in eastern Utah with Grand Junction, Colorado, the largest city in the region. Part of the highway was merged into the Utah state highway system in 1931; the rest was taken over by the state and assigned route number 128 in 1933. Today, the highway is used as a scenic drive for visitors to the area. (Full article...) -
Image 10US 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...) -
Image 11M-35 is a state trunkline highway in the Upper Peninsula (UP) of the US state of Michigan. It runs for 128 miles (206 km) in a general north–south direction and connects the cities of Menominee, Escanaba, and Negaunee. The southern section of M-35 in Menominee and Delta counties carries two additional designations; M-35 forms a segment of the Lake Michigan Circle Tour, and it is the UP Hidden Coast Recreational Heritage Trail, which is a part of what is now called the Pure Michigan Byways Program. Along the southern section, the highway is the closest trunkline to the Green Bay, a section of Lake Michigan. The northern section of the highway turns inland through sylvan areas of the UP, connecting rural portions of Delta and Marquette counties.
M-35 is an original state trunkline that was first signposted in 1919, that was intended to run from Menominee in the south to near Big Bay in the north, before it was to turn toward L'Anse to end at Ontonagon. However, the section through the Huron Mountains in northern Marquette and Baraga counties was never built. Automobile pioneer Henry Ford helped halt this construction to gain favor with and membership into the exclusive Huron Mountain Club. Some discontinuous sections were later ceded to local control. The northern segment of the route between Ontonagon and Baraga was retained as a discontinuous segment of the highway; this northern segment was later redesignated as M-38, another state trunkline. The northern end was later rerouted out of the City of Negaunee into Negaunee Township to avoid mining activity near Palmer. (Full article...) -
Image 12The Kansas Turnpike is a 236-mile (380 km) controlled-access toll road that lies entirely within the US state of Kansas. It runs in a general southwest–northeast direction from the Oklahoma border to Kansas City. It passes through several major Kansas cities, including Wichita, Topeka, and Lawrence. The turnpike is owned and maintained by the Kansas Turnpike Authority (KTA), which is headquartered in Wichita.
The Kansas Turnpike was built from 1954 to 1956, predating the Interstate Highway System. While not part of the system's early plans, the turnpike was eventually incorporated into the Interstate System in late 1956 and is designated today as four different Interstate Highway routes: Interstate 35 (I-35), Interstate 335 (I-335), I-470, and I-70. The turnpike also carries a piece of two U.S. Highways: U.S. Highway 24 (US-24) and US-40 in Kansas City. (Full article...) -
Image 13U.S. Route 50 (US 50) is a transcontinental highway in the United States, stretching from West Sacramento, California, in the west to Ocean City, Maryland, on the east coast. The Nevada portion crosses the center of the state and was named "The Loneliest Road in America" by Life magazine in July 1986. The name was intended as a pejorative, but Nevada officials seized it as a marketing slogan. The name originates from large desolate areas traversed by the route, with few or no signs of civilization. The highway crosses several large desert valleys separated by numerous mountain ranges towering over the valley floors, in what is known as the Basin and Range province of the Great Basin.
US 50 has a diverse route through the state, traversing the resort communities of Lake Tahoe, the state capital in Carson City, historical sites such as Fort Churchill State Historic Park, petroglyphs, alpine forests, desert valleys, ghost towns, and Great Basin National Park. (Full article...) -
Image 14New York State Route 373 (NY 373) is a short state highway in Essex County, New York, within Adirondack Park. It begins at U.S. Route 9 (US 9) and proceeds eastward, ending at a ferry landing on Lake Champlain. It intersects two county routes, several local roads, and a reference route—NY 912T—which connects it with US 9. NY 373 is the only connector between US 9 and the hamlet of Port Kent and the ferry that serves it.
The hamlet of Port Kent and the connecting road were originally built in 1823. The village was planned to act as a source of labor for iron manufacturing and to provide for the industrial needs of Essex County. The hamlet grew and eventually became connected to Burlington, Vermont, via an hour-long ferry across Lake Champlain. The road that accessed Port Kent originally began in Keeseville, but became part of the longer Port Kent and Hopkinton Turnpike in the 1830s. The highway that is now NY 373 was also designated as part of the Theodore Roosevelt International Highway in 1919. (Full article...) -
Image 15M-28 is an east–west state trunkline highway that traverses nearly all of the Upper Peninsula of the U.S. state of Michigan, from Wakefield to near Sault Ste. Marie in Bruce Township. Along with US Highway 2 (US 2), M-28 forms a pair of primary highways linking the Upper Peninsula from end to end, providing a major access route for traffic from Michigan and Canada along the southern shore of Lake Superior. M-28 is the longest state trunkline in Michigan numbered with the "M-" prefix at 290.373 miles (467.310 km). The entire highway is listed on the National Highway System, while three sections of M-28 are part of the Lake Superior Circle Tour. M-28 also carries two memorial highway designations along its route.
Throughout its course across the Upper Peninsula, M-28 passes through forested woodlands, bog swamps, urbanized areas, and along the Lake Superior shoreline. Sections of roadway cross the Ottawa National Forest and both units of the Hiawatha National Forest. Some of the other landmarks accessible from M-28 include the Seney Stretch, Seney National Wildlife Refuge and several historic bridges. (Full article...)

Image 1M-138 is a 20-mile-long (32 km) east–west state trunkline highway in The Thumb region of the US state of Michigan. The highway runs from a junction with M-15 west of the unincorporated community of Munger in Bay County to the intersection with M-24 east of Akron in Tuscola County. The trunkline runs through rural agricultural areas outside of the villages and communities it serves. It was designated in the 1930s and extended in the 1940s. M-138 was truncated in the 1990s as well. (Full article...)

Image 2State Route 99 (SR 99), also known as the Pacific Highway, is a state highway in the Seattle metropolitan area, part of the U.S. state of Washington. It runs 49 miles (79 km) from Fife to Everett, passing through the cities of Federal Way, SeaTac, Seattle, Shoreline, and Lynnwood. The route primarily follows arterial streets, including Aurora Avenue, and has several freeway segments, including the tolled SR 99 Tunnel in Downtown Seattle. SR 99 was officially named the William P. Stewart Memorial Highway by the state legislature in 2016, after a campaign to replace an unofficial moniker honoring Confederate president Jefferson Davis.
SR 99 was originally a section of U.S. Route 99 (US 99), which was once the state's primary north–south highway before the construction of I-5. US 99 was created in 1926 and replaced earlier local roads that date back to the 1890s and state roads designated as early as 1913. The highway was moved onto the Alaskan Way Viaduct in 1953, replacing a congested stretch through Downtown Seattle, and other sections were built to expressway standards in the 1950s.

Image 3K-117 is an approximately 11.98-mile-long (19.28 km) state highway in the U.S. state of Kansas. K-117's southern terminus is at U.S. Route 36 (US-36) in Midway, which is between Atwood and Oberlin. The highway heads north and passes by Herndon before reaching the Nebraska border, where it continues as Nebraska Highway 17 (N-17). K-117 is a two-lane highway its entire length.
In January 1937, it was approved to add the highway to the State Highway System when the Nebraska Department of Transportation (NDOT) had finished their portion of the highway. K-117 was first designated as a state highway on May 26, 1937, to connect to the new highway that was completed by NDOT. K-117's alignment has not changed since it was designated. At times, sections of the highway have had to be closed due to flooding from Beaver Creek. (Full article...) -
Image 4M-17 is a 6.390-mile-long (10.284 km) state trunkline highway in the U.S. state of Michigan, connecting the cities of Ypsilanti and Ann Arbor in Washtenaw County. It was once part of a highway that spanned the southern Lower Peninsula of Michigan before the creation of the U.S. Highway System in 1926. The designation once extended into downtown Detroit, but the eastern terminus was progressively scaled back in the late 1960s to the current location in Ypsilanti. The changes made to the highways in Washtenaw County spawned Business M-17 (Bus. M-17), a business loop for 11 years between 1945 and 1956. (Full article...)

Image 5M-114 was the designation of a former state trunkline highway and planned beltline in the US state of Michigan around the city of Grand Rapids. It was designated by the end of 1929 on various streets in adjoining cities and townships. By the 1940s, sections of it on the west and south sides of Grand Rapids were given new designations and the segment along the east side of town was finished. By late 1945 the highway designation was completely decommissioned in favor of other numbers. M-114 split into two branches, one running east–west and the other running north–south. The east–west spur routing is now local streets while the rest is part of state highways. (Full article...)

Image 6Maryland Route 23 (MD 23) is a state highway in the U.S. state of Maryland. The state highway runs 20.58 miles (33.12 km) from U.S. Route 1 (US 1) in Hickory north and west to the Pennsylvania state line near Norrisville, where the highway continues as Pennsylvania Route 24 (PA 24). MD 23 is an L-shaped highway in northwestern Harford County that consists of two major sections. Between US 1 and MD 165 in Jarrettsville, MD 23 is marked east–west along a two-lane road with partial control of access named East–West Highway. From MD 165 to the state line, the state highway is marked north–south along Norrisville Road, a rural two-lane highway that passes through the villages of Madonna and Shawsville. The two sections of MD 23 are connected by a short concurrency with MD 165.
MD 23 from Hickory to Jarrettsville was one of the original state highways marked for improvement by the Maryland State Roads Commission in 1909 and one of the original state-numbered highways in 1927. The state road was constructed from Hickory to Jarrettsville and from Norrisville to the state line in the early to mid-1910s. The gaps between Jarrettsville and Shawsville and from Shawsville to Norrisville were filled in the early 1920s. East–West Highway was constructed in the early 1960s to replace the parallel Jarrettsville Road. MD 23's eastern terminus was moved to US 1's new bypass of Hickory in 2000. (Full article...) -
Image 7New York State Route 287 (NY 287) was a state highway within the town of Alexandria in Jefferson County, New York, in the United States. The route served as a connector between NY 283 southeast of Alexandria Bay in the hamlet of Browns Corners and NY 37 in the hamlet of Redwood. It was 3 miles (5 km) long and passed through open fields for most of its length.
NY 287 was originally designated as part of NY 3 in 1924. In 1930, NY 3 was rerouted east of Watertown to follow a more southerly routing across the North Country. The Browns Corners–Redwood portion of its former alignment was redesignated as New York State Route 26B by the following year. NY 26, NY 26B's parent route, was truncated southward on July 1, 1977; as a result, NY 26B was redesignated as NY 287. In 1979, ownership and maintenance of NY 287 was transferred from the state of New York to Jefferson County as part of a highway maintenance swap between the two levels of government. The route is now designated as County Route 192 (CR 192). (Full article...) -
Image 8New York State Route 12 (NY 12) is a state highway extending for 222.27 miles (357.71 km) through central and northern New York in the United States. The southern terminus of the route is at U.S. Route 11 (US 11) in the town of Chenango (just north of Binghamton) in the Southern Tier. The northern terminus is at NY 37 near the village of Morristown in the North Country. In between, the route serves three cities of varying size: Norwich, Utica, and Watertown. NY 12 intersects several primary routes, including US 20 in Sangerfield, New York State Thruway via Interstate 790 (I-790) in Utica, overlaps NY 28 from Barneveld to the town of Remsen, NY 3 in Watertown, and I-81 in Pamelia and Orleans.
It is a two lane, undivided, full access roadway for the majority of its length, except between the village of New Hartford and Alder Creek, where it is a four-lane highway. Within that span, it is a limited access highway in the city of Utica, referred locally as The Arterial and the North–South Arterial. The distance between Utica and Binghamton is a major trucking route, and features many gas stations, truck stops, and fast food restaurants. Between Boonville and Lowville, it follows the Black River Valley. Then further north, between Watertown and Morristown, it follows the St. Lawrence River valley. (Full article...) -
Image 9U.S. Highway 136 (US 136) is a short U.S. Highway in Keokuk, Iowa. The route was designated nationally in 1951 and has remained largely unchanged through Keokuk since then. The highway originally crossed the Mississippi on the Keokuk Rail Bridge, which was the second bridge built and operated by Andrew Carnegie's Keokuk & Hamilton Bridge Company in that location. While it was designed for wagons and early automobiles, crossing the rail bridge became difficult in larger modern vehicles, specifically semi trucks. As a result, a new automobile-only bridge was built directly to the south of the older span. The Keokuk–Hamilton Bridge opened in 1985 eight months early and under budget. (Full article...)

Image 10New York State Route 317 (NY 317) is a 3.12-mile (5.02 km) long state highway within the town of Elbridge in Onondaga County, New York, in the United States. It begins at an intersection with NY 5 in the village of Elbridge and ends at a junction with NY 31 in the village of Jordan. The highway is known locally as Jordan Road and Main Street.
The route was once part of the Jordan and Skaneateles Plank Road, a plank road established by a New York State Legislature charter in the 1850s. It spanned a short distance from Jordan to the village of Skaneateles and was a successor to the Auburn and Syracuse Railroad,[disputed – discuss] which ceased operations in 1834. However, the plank road lasted less than two decades. In 1866, the Legislature granted another charter, this time creating the Skaneateles Railroad and its corporation, which bought out most of the plank road company. (Full article...) -

Kansas Highway 47 at junction with US 59, facing east
K-47 is an approximately 61.6-mile-long (99.1 km) state highway in the U.S. state of Kansas. It is an east-west route, and connects small towns and cities in southeast Kansas. K-47's western terminus is at the Fredonia city limits, just west of the intersection with U.S. Route 400 (US-400). The eastern terminus is US-69 in Franklin. Along the way, it intersects several major highways including US-75 in Altoona, US-59 south of Erie, and K-7 in Girard. With the exception of the cities K-47 passes through, the highway travels through rural farmland.
K-47 was established as a state highway in 1928, to a highway that ran from Fredonia northeast to Buffalo. By 1929, it was extended east from Fredonia, through Altoona to modern day US-169 south of Chanute. By 1930, K-47 was truncated to end by Fredonia, with the former section between there and Benedict becoming a realignment of K-39. In 1937, K-47 was extended from Fredonia in a northwest direction, along the former alignment of K-96, through New Albany to new K-96. K-47 was extended east to US-59 south of Erie by 1950. In 1953, K-47's western terminus was truncated back to Fredonia. In 2003, K-47 was extended east over the former K-57 to US-69 by Franklin. (Full article...) -
