The United States Numbered Highway System is an integrated network of roads and highways numbered within a nationwide grid in the contiguous United States. As the designation and numbering of these highways were coordinated among the states, they are sometimes called Federal Highways, but the roadways were built and have always been maintained by state or local governments since their initial designation in 1926.
U.S. Route 425 (US 425) is a north–south United States highway that travels in the U.S. states of Mississippi, Louisiana, and Arkansas. It was first commissioned in 1989.
U.S. Route 165 is a north–south United States highway spur of U.S. Highway 65. It currently runs for 412 miles (663 km) from U.S. Route 90 in Iowa, Louisiana north to U.S. Highway 70 in North Little Rock, Arkansas. The route passes through the states of Arkansas and Louisiana. It passes through the cities of Monroe and Alexandria in Louisiana. A segment of US 165 serves as a routing of the Great River Road within Arkansas.
Texas state highways are a network of highways owned and maintained by the U.S. state of Texas. The Texas Department of Transportation (TxDOT) is the state agency responsible for the day-to-day operations and maintenance of the system. Texas has the largest state highway system, followed closely by North Carolina's state highway system. In addition to the nationally numbered Interstate Highways and U.S. Highways, the highway system consists of a main network of state highways, loops, spurs, and beltways that provide local access to the other highways. The system also includes a large network of farm to market roads that connect rural areas of the state with urban areas and the rest of the state highway system. The state also owns and maintains some park and recreational roads located near and within state and national parks, as well as recreational areas. All state highways, regardless of classification, are paved roads. The Old San Antonio Road, also known as the El Camino Real, is the oldest highway in the United States, first being blazed in 1691. The length of the highways varies from US 83's 893.4 miles (1,437.8 km) inside the state borders to Spur 200 at just 0.05 miles long.
Highway 7 is a north–south state highway that runs across the state of Arkansas. As Arkansas's longest state highway, the route runs 297.27 miles (478.41 km) from Louisiana Highway 558 at the Louisiana state line north to Bull Shoals Lake at Diamond City near the Missouri state line. With the exception of the segment north of Harrison, Highway 7 has been designated as an Arkansas Scenic Byway and a National Forest Scenic Byway. The road passes through the heart of both the Ozark Mountains and the Ouachita Mountains, and features scenic views. It's the route favored by motorcycle riders touring the region.
Maryland Route 331 (MD 331) is a 28.74-mile (46.25 km) state highway on the Eastern Shore of Maryland in the United States. Signed north-south, the route runs from Vienna in Dorchester County northwest to Easton in Talbot County, intersecting U.S. Route 50 (US 50) at both ends. MD 331 is a two-lane undivided road most of its length that passes mostly through agricultural areas. The road also passes through the communities of Hurlock and Preston along the way. It encounters several routes during its journey, including MD 14 near Rhodesdale and MD 16 in the Preston area, both of which the route forms concurrencies with. In addition, the route also intersects with MD 392 and MD 307 in Hurlock and with MD 318 near Preston.
Arkansas Highway 12 is an east–west state highway in Northwest Arkansas. The route runs 56.60 miles (91.09 km) from Oklahoma State Highway 116 near Cherokee City east to Arkansas Highway 23 near Clifty.
Maryland Route 300 is a state highway in the U.S. state of Maryland. Known for most of its length as Sudlersville Road, the highway runs 13.55 miles (21.81 km) from MD 213 in Church Hill east through Sudlersville to the Delaware state line, where the highway continues as Delaware Route 300. MD 300 forms part of an east–west connection between U.S. Route 301 in northern Queen Anne's County and Dover, Delaware. MD 300 between Church Hill and Dudley Corners was one of the original state roads marked for improvement in 1909, but the county constructed the highway with state aid in the mid- to late-1910s from Church Hill to Sudlersville. The highway from Sudlersville to the state line was built in the late 1920s and early 1930s. MD 300 was widened over its entire length around 1950 and extended west to US 213's bypass of Church Hill around 1970. MD 300 was officially split in two when its superstreet intersection with US 301 was built in 2005.
U.S. Route 219 (US 219) is a part of the U.S. Highway System that runs from Rich Creek, Virginia, to West Seneca, New York. In the U.S. state of Maryland, the U.S. Highway runs 48.40 miles (77.89 km) from the West Virginia state line near Redhouse to the Pennsylvania state line near Grantsville. Known as Garrett Highway for much of its length in Maryland, US 219 is the primary north–south route in Garrett County, connecting Interstate 68 (I-68) and Oakland. The highway also provides the main access to the resort area of Deep Creek Lake, which includes Maryland's only ski area, Wisp Ski Resort.
The Wendover Cut-off, also called the Wendover Road or Wendover Route, is a two-lane highway in the western part of Tooele County in the U.S. state of Utah. Stretching 40.3 miles (64.9 km) from Wendover to Knolls across the Bonneville Salt Flats, a part of the Great Salt Lake Desert, the cut-off was once part of the primary link between the Nevada state line and Salt Lake City. In 2012, between 240 and 250 vehicles used the cut-off near its western terminus in Wendover on an average day.
The State Route System of Tennessee is maintained and developed by the Tennessee Department of Transportation (TDOT) in the U.S. state of Tennessee. Currently the state has 14,150 miles (22,770 km) of state-maintained roadways, including 1,233 miles (1,984 km) of Interstate Highways and 13,077 miles (21,045 km) of State Highways. All of the U.S. Routes in Tennessee have a state route routed concurrently with them, though the state route is hidden and only signed along the green mile marker signs that display mileage within each county. The state route system in Tennessee was established in 1923. Since the 1983 renumbering, state routes have been divided into primary and secondary routes with separate shields used for each.
K-19 is a 33.915-mile-long (54.581 km) state highway in the U.S. state of Kansas. From U.S. Route 50 (US-50) to K-19 Spur it is signed as north–south and from K-19 Spur to US-281 it is signed as east–west. K-19's southern terminus is at US-50 in Belpre, and the eastern terminus is at US-281 east of Seward.

The State Trunkline Highway System consists of all the state highways in Michigan, including those designated as Interstate, United States Numbered, or State Trunkline highways. In their abbreviated format, these classifications are applied to highway numbers with an I-, US, or M- prefix, respectively. The system is maintained by the Michigan Department of Transportation (MDOT) and comprises 9,669 miles (15,561 km) of trunklines in all 83 counties of the state on both the Upper and Lower peninsulas, which are linked by the Mackinac Bridge. Components of the system range in scale from 10-lane urban freeways with local-express lanes to two-lane rural undivided highways to a non-motorized highway on Mackinac Island where cars are forbidden. The longest highway is nearly 400 miles (640 km) long, while the shortest is about three-quarters of a mile. Some roads are unsigned highways, lacking signage to indicate their maintenance by MDOT; these may be remnants of highways that are still under state control whose designations were decommissioned or roadway segments left over from realignment projects.
Highway 38 is a designation for three state highways in Arkansas. One route of 49.58 miles (79.79 km) runs east from Highway 367 at Cabot to US Route 49 (US 49) near Hunter.

All routes are maintained by the Arkansas State Highway and Transportation Department (AHTD).
Maryland Route 858 is a collection of unsigned state highways in the U.S. state of Maryland. These four highways are old segments of MD 67 between Rohrersville and Boonsboro in southeastern Washington County. These highways were designated when MD 67 was relocated in the early 1960s. The longest segment is MD 858F, which runs exactly 1 mile (1.6 km) between a pair of intersections with MD 67 in Rohrersville. In addition to the four existing highways, there are several county-maintained segments of old MD 67 between Rohrersville and Boonsboro and at Gapland, Brownsville, and Weverton south of Rohrersville.
The Arkansas Highway System is made up of all the highways designated as Interstates, U.S. Highways and State Highways in the US state of Arkansas. The system is maintained by the Arkansas Department of Transportation (ArDOT), known as the Arkansas State Highway Department (AHD) until 1977 and the Arkansas State Highway and Transportation Department (AHTD) from 1977 to 2017. The system contains 16,442.90 miles (26,462.28 km) of Interstates, U.S. Routes, state highways, and special routes. The shortest members are unsigned state highways Arkansas Highway 806 and Arkansas Highway 885, both 0.09 miles (0.14 km) in length. The longest route is U.S. Route 67, which runs 296.95 miles (477.89 km) from Texarkana to Missouri.
Eight special routes of U.S. Route 82 currently exist. Three of them lie within the state of Arkansas, with five more in Texas, and one in Georgia. Seven more existed in the past but have since been decommissioned.
