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 1Interstate 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.

It runs 9.210 miles (14.822 km) from Interstate 5 (I-5) in the Carmel Valley neighborhood of San Diego to I-15. The eastern terminus of the highway is also the western end of the Ted Williams Parkway. SR 56 serves as an important connector between I-5 and I-15, being the only east–west freeway between SR 78 in north San Diego County, several miles away, and SR 52 near Marine Corps Air Station Miramar. It is also named the Ted Williams Freeway, after the San Diego-born baseball player.
SR 56 was added to the state highway system in 1959 as Legislative Route 278, and was renumbered SR 56 in the 1964 state highway renumbering. Plans in 1964 were to connect SR 56 to the north end of SR 125 and continue east to SR 67, but these plans did not come to fruition. The eastern end from Black Mountain Road to I-15 was completed in 1993; the western end from I-5 to Carmel Creek Road was completed in 1995 after several lawsuits filed by the Sierra Club and other community groups. The two ends were not connected until the middle portion of the freeway was completed in 2004. The delay was largely due to funding issues and environmental concerns. (Full article...) - Image 3Interstate 96 (I-96) is an east–west Interstate Highway that runs for approximately 192 miles (309 km) entirely within the Lower Peninsula of the US state of Michigan. The western terminus is at an interchange with US Highway 31 (US 31) and Business US 31 (Bus. US 31) on the eastern boundary of Norton Shores southeast of Muskegon, and the eastern terminus is at I-75 near the Ambassador Bridge in Detroit. From Grand Rapids through Lansing to Detroit, the freeway parallels Grand River Avenue, never straying more than a few miles from the decommissioned US 16. The Wayne County section of I-96 is named the Jeffries Freeway from its eastern terminus to the junction with I-275 and M-14. Though maps still refer to the freeway as the Jeffries, the portion within the city of Detroit was renamed by the state legislature as the Rosa Parks Memorial Highway in December 2005 in honor of the late civil rights pioneer. There are four auxiliary Interstates as well as two current and four former business routes associated with I-96.
Grand River Avenue originated as an Indian trail before Michigan statehood. It later was used as a wagon road across the state. The roadway was included in the State Trunkline Highway System in 1919 as M-16 and later the United States Numbered Highway System as US 16. Construction of a freeway along the length of the corridor was proposed in the 1940s, and included as part of the Interstate Highway System in the mid-1950s. This construction was started in 1956 and initially completed across the state to Detroit in 1962. The proposed route for the Jeffries Freeway in Detroit was moved in the 1960s; it was built in the 1970s. I-96 was completed on November 21, 1977, in the Detroit area, closing the last gap along the route. Since then, additional interchanges and lanes have been added in places to accommodate traffic needs.

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...) - Image 5U.S. Route 101, or U.S. Highway 101 (US 101), is a major north–south highway that traverses the states of California, Oregon, and Washington on the West Coast of the United States. It is part of the United States Numbered Highway System and runs for over 1,500 miles (2,400 km) along the Pacific Ocean. The highway is also known by various names, including El Camino Real in parts of California, the Oregon Coast Highway, and the Olympic Highway in Washington. Despite its three-digit number, normally used for spur routes, US 101 is classified as a primary route with 10 as its "first digit".
The highway's southern terminus is at a major interchange with Interstate 5 (I-5) and I-10 in Los Angeles. US 101 follows several freeways in Southern California as it travels north of the Santa Monica Mountains and along the coast, where it is concurrent with California State Route 1 (SR 1). The highway travels inland from the coast after it splits from SR 1 and approaches the San Francisco Bay Area, where it becomes the Bayshore Freeway and later traverses San Francisco on city streets to reach the Golden Gate Bridge. US 101 continues north on the Redwood Highway and rejoins the coast before it enters Oregon. (Full article...) - Image 6US Highway 141 (US 141) is a north–south United States Numbered Highway in the states of Wisconsin and Michigan. The highway runs north-northwesterly from an interchange with Interstate 43 (I-43) in Bellevue, Wisconsin, near Green Bay, to a junction with US 41/M-28 near Covington, Michigan. In between, it follows city streets in Green Bay and has a concurrent section with US 41 in Wisconsin. North of Green Bay, US 141 is either a freeway or an expressway into rural northern Wisconsin before downgrading to an undivided highway. In Michigan, US 141 is an undivided highway that runs through rural woodlands. The highway has two segments in each state; after running through Wisconsin for about 103 miles (166 km), it crosses into Michigan for approximately another eight miles (13 km). After that, it crosses back into Wisconsin for about 14+1⁄2 miles (23 km) before crossing the state line one last time. The northernmost Michigan section is about 43+1⁄2 miles (70 km), making the overall length about 169 miles (272 km).
When the US Highway System was formed on November 11, 1926, US 141 ran from Milwaukee to Green Bay, and one segment of the modern highway in Michigan was originally designated US Highway 102 (US 102). This other designation was decommissioned in 1928 when US 141 was extended north from Green Bay into Michigan. Michigan has rebuilt the highway in stages over the years to smooth out sharp curves in the routing. Since the 1960s, the section south of Green Bay has been converted into a freeway in segments. US 141 has ended southeast of Green Bay in Bellevue since the 1980s—the southern freeway segment was redesignated as I-43. The section north of Abrams, Wisconsin, was converted to a freeway in the opening years of the 21st century, with an additional divided-highway section opening a few years later.

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...) - Image 8Interstate 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 9State Route 522 (SR 522) is a state highway in the U.S. state of Washington that serves the Seattle metropolitan area. Approximately 25 miles (40 km) long, it connects the city of Seattle to the northeastern suburbs of Kenmore, Bothell, Woodinville, and Monroe. Its western half is primarily an arterial street, named Lake City Way and Bothell Way, that follows the northern shore of Lake Washington; the eastern half is a grade-separated freeway that runs between Woodinville and Monroe. SR 522 connects several of the metropolitan area's major highways, including Interstate 5 (I-5), I-405, SR 9, and U.S. Route 2 (US 2).
The present-day route of SR 522 was built in stages between 1907 and 1965, beginning with the Red Brick Road from Seattle to Bothell, then part of the Pacific Highway and later US 99. The road later became a branch of Primary State Highway 2 (PSH 2) in 1937, and was extended east to Redmond and North Bend. A branch of the Stevens Pass Highway was built to connect PSH 2 in Bothell and Monroe in 1965, and was incorporated into SR 202 after it was designated in 1964. The Bothell–Monroe highway was re-designated as part of SR 522 in 1970, leaving SR 202 on the Bothell–North Bend highway. (Full article...) - Image 10M-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 11Business US Highway 41 (Bus. US 41) was a state trunkline highway that served as a business loop off US 41 and M-28 in Marquette, Michigan, along Washington and Front streets. The streets serve the downtown area of Marquette and are bordered by several commercial properties and businesses. Those two streets originate with the early founding of the city in the middle of the 19th century. Jurisdiction over them was transferred to the city as part of a highway swap that resulted in the decommissioning of the trunkline in 2005. It was also previously co-designated Bus. M-28, mirroring the Bus. US 41/Bus. M-28 designation previously used along Bus. M-28 in Ishpeming and Negaunee. Washington and Front streets had been a part of the state highway system since the 1910s, and a part of the United States Numbered Highway System since 1926. The business loop designation dates back to the 1960s and was removed in 2005. (Full article...)
- Image 12New York State Route 174 (NY 174) is a state highway in Onondaga 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 41 in Borodino, 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...) - Image 13H-58 is a county-designated highway in the US state of Michigan that runs east–west for approximately 69 miles (111 km) between the communities of Munising and Deer Park in the Upper Peninsula. The western section is routed through Pictured Rocks National Lakeshore, along the southern shore of Lake Superior, and the adjacent Lake Superior State Forest in Alger County while connecting Munising to the communities of Van Meer and Melstrand. At Grand Marais, H-58 exits the national lakeshore area and runs through town. The segment running east of Grand Marais to Deer Park in Luce County is a gravel road that connects to H-37 in Muskallonge Lake State Park.
A roadway was present along parts of today's H-58 by the late 1920s; initially, this county road was gravel or earth between Munising and Kingston Corners and connected with other roads to Grand Marais. In the 1930s, another segment was built to connect to Deer Park and to fill in the gap between Kingston Corners and Grand Marais. The southwestern segment between Munising and Van Meer formed part of M-94 from 1929 until it was transferred back to county control in the early 1960s. (Full article...) - Image 14Interstate 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...) - Image 15Interstate 69 (I-69) is a part of the Interstate Highway System that will eventually run from the Mexican border in Texas to the Canadian border at Port Huron, Michigan. In Michigan, it is a state trunkline highway that enters the state south of Coldwater and passes the cities of Lansing and Flint in the Lower Peninsula. A north–south freeway from the Indiana–Michigan border to the Lansing area, it changes direction to east–west after running concurrently with I-96. The freeway continues to Port Huron before terminating in the middle of the twin-span Blue Water Bridge while running concurrently with I-94 at the border. There are four related business loops for I-69 in the state, connecting the freeway to adjacent cities.
Predecessors to I-69 include the first M-29, US Highway 27 (US 27), M-78 and M-21. The freeway was not included on the original Interstate Highway System planning maps in the mid-1950s, but it was added in 1958 along a shorter route. Michigan built segments of freeway for the future Interstate in the 1960s, and the state was granted additional Interstate mileage in 1968 to extend I-69 north and east to Flint. Later extensions in 1973 and 1987 resulted in the modern-day highway. The first freeway segment designated as I-69 in Michigan opened in 1967, and the last was completed in 1992, finishing Michigan's Interstate System. US 27 previously ran concurrently with I-69 from the Indiana–Michigan state line north to the Lansing area, but this designation was removed in 2002. (Full article...)
- Image 1Mississippi Highway 53 (MS 53) is a state highway in Mississippi. The highway starts at U.S. Highway 49 (US 49) in Gulfport and travels northwestward to MS 603 in Hancock County. The road then travels north to Poplarville, meeting Interstate 59 (I-59). MS 53 ends at MS 26 and US 11 in southwestern Poplarville. The road that became MS 53 has existed since 1928, and the highway was designated in 1950. The highway was completely paved by 1957, and an interchange was created at I-59 in 1967. (Full article...)
- Image 2State Route 249 (SR 249) is an Ohio State Route that runs between the Indiana state line and Ney in the U.S. state of Ohio. The 14.45 miles (23.26 km) of SR 249 that lie within the state serve as a minor highway. None of the highway is listed on the National Highway System. The whole route is a rural two-lane highway and passes through farmland. The highway was first signed in 1925 and was a north–south route, a route that later became U.S. Route 127 (US 127). SR 249 was given its current route in 1927, as a replacement for SR 22. The route was completely paved by 1942. (Full article...)
- Image 3M-239 is a north–south state trunkline highway in Berrien County in the extreme southwestern corner of the US state of Michigan connecting State Road 39 (SR 39) in Indiana to Interstate 94 (I-94). The highway was designated in 1963, and it provided the only connection from the southern end of I-94 into Indiana until 1972. (Full article...)

State Highway 58 (abbreviated SH-58) is the name of two state highways in Oklahoma. One of them runs for 72.7 miles (117.0 km) from Medicine Park to the Blaine–Custer County line near Hydro, and the other connects US-270/281/SH-3/33 to the Kansas state line, a length of 105.9 mi (170.4 km). The northern section has one lettered spur route, SH-58A.
SH-58 was originally a part of US-164. When US-164 was decommissioned in 1930, a section of the road in Major County that was left without a designation became SH-58. Since then, the highway has grown toward both the north and the south. With the designation and extension of the southern section of the highway, SH-58 is present in five counties in the western part of the state.

It extends for 2.31 miles (3.72 km) from an intersection with NY 5 in the city of Syracuse to a junction with NY 298 in the adjacent town of Salina. The route intersects Interstate 690 (I-690) near its southern terminus and passes through Syracuse's Eastwood neighborhood near its midpoint, where it meets NY 290.
NY 598 was assigned c. 2004. The northernmost portion of the route replaced NY 930M, a short unsigned reference route that extended from NY 298 in Salina southeast to the Syracuse city line at North Midler Avenue. NY 930M itself was a remnant of New York State Route 433, a highway assigned in the early 1950s and removed in the mid-1960s that, upon removal, followed the same alignment as modern NY 598.

The state highway runs 18.50 miles (29.77 km) from U.S. Route 40 (US 40) in Clear Spring east to US 40 Alternate in Boonsboro. MD 68 crosses central Washington County to the south of Hagerstown, connecting Clear Spring and Boonsboro with Williamsport, where the highway runs concurrently with MD 63. A small segment of MD 68 west of Boonsboro was constructed around 1920, using as part of the route two early 19th-century stone bridges. The remainder of the highway between Boonsboro and Williamsport was constructed in the second half of the 1920s. MD 68 was extended west from Williamsport to Clear Spring in the mid-1950s. The state highway was relocated south of Williamsport for the construction of Interstate 81 (I-81) in the mid-1960s. Since the early 1990s, I-68 has also existed in Washington County; signs on I-70 aim to avoid confusion between I-68 and MD 68. (Full article...)
- Image 7M-146 was a state trunkline highway in the US state of Michigan that initially served as a bypass for traffic going around Port Huron and as a short cut for traffic between U.S. Highway 25 (US 25) and M-21. Later it connected to the Blue Water Bridge before it was truncated to its final form. Segments of M-146 still exist today as state highways as part of Interstate 94 (I-94) and I-69 and the Lapeer Connector. (Full article...)

Park Road 2 is located in Harrison County, in the northeastern region of the U.S. state of Texas. The Civilian Conservation Corps constructed the road in the 1930s, and the road was designated in 1937 as one of the original park roads in the state highway system. (Full article...)
- Image 9New York State Route 120A (NY 120A) is a state highway in southern Westchester County, New York, in the United States. It serves as an alternate route to the southern half of NY 120 running along the New York–Connecticut state line. The southern terminus of the route is at NY 120 in Harrison. Its northern terminus is at NY 120 in North Castle. Most of the 8.55-mile (13.76 km) route straddles the New York–Connecticut state line, and part of the route is physically located in Connecticut. However, this part of the highway is not recognized by Connecticut as "Route 120A", and is considered to be part of NY 120A by the New York State Department of Transportation (NYSDOT).

- Image 10The Baltimore–Washington Parkway (also referred to as the B–W Parkway) is a controlled-access parkway in the U.S. state of Maryland, running southwest from Baltimore to Washington, D.C. The road begins at an interchange with U.S. Route 50 (US 50) near Cheverly in Prince George's County at the Washington, D.C., border, and continues northeast as a parkway maintained by the National Park Service (NPS) to MD 175 near Fort Meade, serving many federal institutions. This portion of the parkway is dedicated to Gladys Noon Spellman, a representative of Maryland's 5th congressional district, and has the unsigned Maryland Route 295 (MD 295) designation. Commercial vehicles, including trucks, are prohibited within this stretch. This section is administered by the NPS's Greenbelt Park unit. After leaving park service boundaries the highway is maintained by the state and signed with the MD 295 designation. This section of the parkway passes near Baltimore–Washington International Thurgood Marshall Airport.
Upon entering Baltimore, the Baltimore Department of Transportation takes over maintenance of the road and it continues north to an interchange with Interstate 95 (I-95). Here, the Baltimore–Washington Parkway ends and MD 295 continues north unsigned on Russell Street, which carries the route north into downtown Baltimore. In downtown Baltimore, MD 295 follows Paca Street northbound and Greene Street southbound before ending at US 40. (Full article...) - Image 11Route 109 is a 3.06-mile (4.92 km) state highway located in Cape May County, New Jersey, United States. The route runs from Jackson Street in Cape May north to an intersection with U.S. Route 9 (US 9) in Lower Township. It crosses one of two road bridges over the Cape May Canal (the other is Route 162) and provides access to the southern end of the Garden State Parkway and County Route 621 (CR 621, Ocean Drive) as well as to Cape May. Only the section of road in Lower Township is state maintained; the rest is maintained by Cape May County and signed as County Route 633 (CR 633), which extends 0.34 mi (0.55 km) past the southern terminus along Jackson Street and Perry Street to CR 626 in West Cape May.
Present-day Route 109 was designated as a part of pre-1927 Route 14 in 1917 before becoming the southernmost portion of Route 4 in 1927. By the 1940s, US 9 extended south to Cape May from Absecon along this part of Route 4. In 1953, the Route 4 designation was dropped from this segment of road to avoid the concurrency with US 9. In 1972, US 9 was rerouted to head to the Cape May–Lewes Ferry terminal, with the former alignment into Cape May becoming Route 109.

It runs for almost eight miles (13 km) along Gull Road between the northeast side of Kalamazoo and continues through rural areas on the way to Richland. The highway was created in January 2019 from a section of M-43 after that highway was rerouted in the aftermath of a series of jurisdictional transfers in downtown Kalamazoo. It had been a part of the state highway system for a century under its previous number until it was given its current designation. (Full article...)
- Image 13K-95 is an approximately 6.6-mile-long (10.6 km) state highway in the U.S. state of Kansas. K-95's southern terminus is at U.S. Route 83 (US-83) north of Scott City, and the northern terminus is at US-83 south of Elkader. The highway forms a section of the Western Vistas Historic Byway. K-95 travels through mostly rural land, and is a two-lane highway its entire length.
Within Lake Scott State Park, just west of K-95, is the El Cuartelejo ruins. It is the remains of a structure thought to have been built by Taos Pueblo Indians who left New Mexico in 1664 to escape Spanish rule. The highway passes about 0.6 miles (970 m) east of the area of the Battle of Punished Woman's Fork, the last Indian battle in the state. The route that K-95 follows was planned to become a state highway in a resolution on July 27, 1966, to link US-83 to Lake Scott and Lake Scott State Park. This alignment was altered in a resolution on May 10, 1967, and was designated as K-95. K-95 first appeared on the 1969 State Highway Map, and its alignment has not changed since.

At its peak, US 80 traveled from the California border in Yuma to the New Mexico state line near Lordsburg. US 80 was an important highway in the development of Arizona's car culture. Like its northern counterpart, US 66, the popularity of travel along US 80 helped lead to the establishment of many unique roadside businesses and attractions, including many iconic motor hotels and restaurants. US 80 was a particularly long highway, reaching a length of almost 500 miles (800 km) within the state of Arizona alone for most of the route's existence.
Along with US 66, US 80 was one of the first U.S. Highways to span Arizona. Where US 66 served northern Arizona, US 80 acted the main interstate highway for the southern half of the state, serving the major cities of Phoenix and Tucson, along with other small towns and cities. The condition of the highway was modernized and improved during the Great Depression, largely through manual labor and funding provided by the Works Progress Administration, which included the grade separation of railroad crossings and paving of the highway. Tourism and traffic along US 80 greatly increased following the end of World War II, creating a temporary economic boom for businesses along the highway. Several areas of the highway were also bypassed or straightened during this time to help alleviate the increasing traffic.

The highway runs along a rail line in a northwest-to-southeast direction in rural Shiawassee County connecting a few small towns along its path.
The highway dates back to the start of the state highway system in 1919. There were some changes made to the routing in the 1930s which increased its length. Two adjacent highways have been rerouted which affected the locations of M-71's termini. The last such change was made in the 1960s when the M-78 freeway (now I-69) was completed near Durand.
