State Route 72 is a 36.74-mile-long (59.13 km) state highway in the U.S. state of Arizona. It runs from SR 95 near Parker southeast to U.S. Route 60 in Hope. Along its route in La Paz County, the highway is mostly parallel to the Arizona and California Railroad and runs through the community of Bouse in desert terrain. The route was established in 1930 from its current eastern terminus all the way to the California state line, but was truncated in 1965. The route was completely paved by 1940.
State Route 80 is a roughly arc-shaped highway lying in southeastern Arizona that, with New Mexico's State Road 80, is a relic of the old U.S. Route 80, now truncated from San Diego to Dallas. This segment of old US 80 was not closely paralleled by Interstate 10, which lies to its north and instead supplants the old and more direct State Route 86.
U.S. Route 163 is a 64-mile (103 km) U.S. Highway that runs from US 160 northward to US 191 in the U.S. states of Arizona and Utah. The southernmost 44 miles (71 km) of its length are within the Navajo Nation. The highway forms part of the Trail of the Ancients, a National Scenic Byway. The highway cuts through the heart of Monument Valley and has been featured in numerous movies and commercials.
State Route 92 is a state highway in the U.S. state of Arizona. Running roughly in an "L"-shaped pattern, SR 92 begins at SR 90 in Sierra Vista and ends at a traffic circle in Bisbee along SR 80, running entirely within Cochise County. The route was constructed and numbered as SR 92 in the late 1930s with a route that traveled further north past Sierra Vista than it does today. The routing was corrected in the 1960s.
State Route 169, also known as SR 169 and Cherry Road, is an east–west highway in central Arizona, with its western terminus at its junction with its parent road State Route 69 at Dewey and its eastern terminus at Exit 278 of Interstate 17. In conjunction with SR 69 and I-17, it serves as the most direct route between Prescott and the Verde Valley, bypassing the scenic, but dangerous mountain grades of State Route 89A through Jerome.
State Route 61, also known as SR 61, is a 76.51-mile-long (123.13 km) state highway in northern Arizona running generally southwest to northeast, from its southern terminus at U.S. Route 60 east of Show Low to the New Mexico border at Zuni, where it becomes New Mexico State Road 53. Parts of this route, particularly near St. Johns, overlap US 180 and US 191.
State Route 71 is a state highway in central Arizona that stretches between its northeast terminus at its junction with State Route 89 at Congress and its southwest terminus at its junction with U.S. Route 60 at Aguila. It primarily serves as a shortcut between Prescott and the major roads going to California as there are no towns located on the route other than at the ends of the highway.
Arizona State Route 78 (SR 78) and New Mexico State Road 78 (NM 78) are a pair of adjoining state highways located in eastern Arizona and western New Mexico linking U.S. Route 191 (US 191) and Arizona State Route 75 near Greenlee County Airport to US 180 northwest of Cliff, New Mexico. It is also known in its Arizona stretch as Mule Creek Road.
State Route 88 is a long state highway in the U.S. state of Arizona. It runs from U.S. Route 60 in Apache Junction through desert terrain to SR 188 near Roosevelt Dam. Following the Salt River for much of its length, the section east of Tortilla Flat is known as the Apache Trail and is part of the National Forest Scenic Byway system. The Apache Trail was built in the mid-1920s and the number 88 was assigned in 1927. An eastern extension of State Route 88 to Globe, Arizona was redesignated as State Route 188 on August 20, 1999.
State Route 73, also known as SR 73, is a U-shaped state highway, though it is signed north–south, primarily serving the Fort Apache Indian Reservation in eastern Arizona. SR 73 begins at a junction with the U.S. Route 60 / State Route 77 concurrency near Carrizo, travels southeast to Fort Apache and Whiteriver, then bends north-northeast until intersecting State Route 260 near the Hon-Dah Resort Casino.
State Route 96, is an east–west, 21.79-mile-long (35.07 km) state highway in central part of the U.S. state of Arizona. It runs from Bagdad east to Yavapai County Road 15 near Hillside. The road was built in the late 1930s and logged as a state route from Bagdad to Hillside in 1962. The section from Bagdad to SR 97 was never officially part of the State Highway system, though the remainder of the highway was officially designated as such at the turn of the century.
State Route 264 (SR 264) is a state highway in northeastern Arizona, that runs from a junction with US 160 near Tuba City to the New Mexico state line at Window Rock, where the highway continues as New Mexico State Road 264.
State Route 266 is a highway in Graham County, Arizona that runs from its junction with US 191 south of Safford to Fort Grant. It is an east–west route.
State Route 286 is a highway in southern Arizona that runs from its junction with State Route 86 west of Tucson to the U.S.-Mexico border at Sasabe. It is largely a north–south route.
State Route 366 is a highway in Graham County, Arizona that runs from its junction with US 191 south of Safford to near the summit of Mount Graham. It is a winding mountain road with one half primarily a northwest-southeast route, the other half being northeast-southwest.
U.S. Route 191 (US 191) is a north–south United States Highway within Arizona. The highway runs for 517 miles (832 km), the longest of any numbered highway in Arizona, from State Route 80 near Douglas to the Utah state line near Mexican Water. As it crosses the state, US 191 overlaps at various points: I-10, US 70, US 180, US 60, SR 61, I-40, SR 264, and US 160. Previously the route was designated as US 666 and SR 63.
U.S. Route 70 (US 70), also known as the Old West Highway, is an east–west U.S. Highway in the U.S. state of Arizona. The current route starts at US 60 in Globe and runs through the San Carlos Indian Reservation, Safford and Duncan into New Mexico near Virden. In Arizona, US 70 passes through mostly isolated hilly and mountainous terrain largely paralleling the course of the Gila River and the Arizona Eastern Railway.
U.S. Route 95 (US 95) is a major U.S. Highway in the American state of Arizona. Starting at the Mexican border in San Luis, US 95 acts as the main highway north through Gadsden, Somerton and Yuma before arriving in Quartzsite. Between Quartzsite and the California border on the Colorado River in Ehrenberg, US 95 runs entirely concurrent with I-10. Part of US 95 between San Luis and Yuma is maintained by local governments instead of the Arizona Department of Transportation, which maintains the remainder of the route.
Below is a list and summary of the unconstructed state highways in the U.S. state of Arizona. Some are currently proposed while the others have since been cancelled prior to being constructed.
