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.
 State Route 30 | |
|---|---|
| Location | Phoenix |
State Route 30 (formerly State Route 801), also known as the I-10 Reliever, is a planned state highway in the southwest parts of Phoenix, Arizona and nearby suburbs. It will connect the southern terminus of Loop 303 with the South Mountain leg of Loop 202. It is planned as a controlled-access freeway to relieve heavy traffic congestion experienced along Interstate 10 in the area.
 State Route 50 | |
|---|---|
| Location | Phoenix to Glendale |
State Route 50, also known as the Paradise Parkway, was a proposed urban freeway through Glendale and Phoenix. Originally proposed in 1968 as SR 317, [1] the freeway would have run east to west, connecting the future State Route 51 and Loop 101, while running roughly parallel to, and 4 miles (6.4 km) north of, I-10 in the vicinity of Camelback Road. The proposed freeway was reassigned as SR 50 in 1987. [2] As the proposed freeway would have crossed through largely developed land and densely populated neighborhoods, it proved to be both extremely expensive and highly unpopular. The route was eventually struck from state planning maps [3] and all land acquired for right-of-way was subsequently sold, the funds being used to pay for other transportation projects.
 U.S. Route 87 | |
|---|---|
| Location | New Mexico to Elfrida (First proposal) New Mexico to Douglas (Second proposal) |
 U.S. Route 87W | |
|---|---|
| Location | Elfrida to Nogales |
 U.S. Route 87E | |
|---|---|
| Location | Elfrida to Douglas |
U.S. Route 87 (US 87) was a proposed extension of US 87 into eastern Arizona. The proposal also included two split routes which would have been designated U.S. Route 87W (US 87W) and U.S. Route 87E (US 87E). The proposed US 87 was created by the Tombstone, Arizona based Border-Sunshine Way Association after a meeting in Tucson and was presented to the Arizona State Highway Department on November 3, 1931. Outside Arizona the proposed extension of US 87 would have been extended from its southern terminus in Rawlins, Wyoming through Colorado and New Mexico to Arizona. This would have established concurrencies with US 30, US 40S, US 50, US 550, US 450 and US 66 as well as replacing US 666 between Cortez, Colorado and Gallup, New Mexico. [4]
US 87 would have entered Arizona from New Mexico on present day State Route 61 near Zuni, New Mexico, running southwest to St. Johns. It would have run concurrent with the original US 70 between St. Johns and Springerville, Arizona. From Springerville, it would have been concurrent with US 60 heading east to SR 71 (now US 191), then would have replaced SR 71 between US 60 and US 180 (the current US 70). US 87 would have been concurrent with US 180 west to Safford, where it would have then replaced SR 81 (now US 191) through Willcox to a junction near Elfrida. The proposed US 87W would have started from US 87 and US 87E near Elfrida, then would have taken Gleeson Road west through Gleeson to Tombstone. US 87W would have had a wrong-way concurrency with US 80 from Tombstone to SR 82. US 87W would have then replaced the entirety of SR 82 between Tombstone Junction and Nogales, establishing a western terminus at US 89. US 87E would have replaced the remainder of SR 81 between Elfrida and Douglas. [5] [4]
The Arizona State Highway Department approved the proposal in 1934 and tried to get US 87 extended into Arizona. [6] The proposed extension of US 87 was ultimately unsuccessful and US 87 was not extended into Arizona by 1935. [7] In an ironic twist, US 666 was extended into Arizona in 1942 along the previously proposed US 87 and US 87E to Douglas. [8] Just 11 years earlier, the US 87 proposal had attempted to replace all of US 666 between Colorado and New Mexico. [4] The Arizona State Highway Department tried a final time in 1943 to extend US 87 into Arizona and requested US 87 replace all of the newly extended US 666 south to Douglas. [9] The attempt was once again unsuccessful, as by 1946, US 666 was still designated between New Mexico and Douglas.[ citation needed ]
 U.S. Route 93T | |
|---|---|
| Location | Kingman to Wickenburg |
U.S. Route 93T was a proposed temporary extension of US 93 following US 66 and US 89 from Kingman to Wickenburg while the final route of US 93 was to be constructed through Wikieup. The idea was abandoned in 1937, the same year it was proposed. The proposal for US 93 to be extended past Kingman towards Phoenix was denied by the AASHO also in 1937. It wouldn't be until 1965 that US 93 would exist south of Kingman. [10]

 State Route 176 | |
|---|---|
| Location | San Manuel to Benson |
State Route 176 was a proposed state highway in eastern central Arizona, that would have connected I-10 in Benson and SR 76 in San Manuel. It was designated in 1967 but was never built, and was cancelled in 1970. The proposed route was added to SR 76. It would have followed the San Pedro River on its entire length. [11] [12]

 U.S. Route 193 | |
|---|---|
| Location | Sacaton to Picacho |
U.S. Route 193 was a proposed U.S. Highway highway that would have taken over the route of SR 87, SR 187 and SR 84 between Sacaton and Picacho, via Casa Grande. It was proposed by the Arizona Highway Department as a branch of a proposed extension of US 93 at the time. By 1937, the route was briefly redesignated US 93A before the proposal was subsequently dropped. The proposed extension of mainline US 93 was denied by the AASHO the same year. [10]

 State Route 380 | |
|---|---|
| Location | St. Johns to New Mexico |
State Route 380 was a proposed state route that was never constructed in the eastern part of the state of Arizona. It was proposed, starting in the town of St. Johns and would have ended at the New Mexico state line. It shows up on some state maps starting in 1970, but was never built. The road proposed is currently a dirt ranch road. In St. John's, it would have begun at a junction with U.S. Route 180, a child of U.S. Route 80. It would have connected with the recently cancelled NM 191.

 State Route 487 | |
|---|---|
| Location | Flagstaff to  SR 87 |
State Route 487 was a state route that never materialized in the north-central part of Arizona. The Arizona Department of Transportation added it the state highway system in 1967 between Flagstaff and State Route 87 near Happy Jack. It did show on state maps during the early 1970s, but the route disappeared in the mid to late '70s. The road currently exists today as Coconino County Road 3.

 Interstate 710 | |
|---|---|
| Location | Tucson |
Interstate 710 (I-710) was proposed to follow the current alignment of the Kino Parkway, an at-grade parkway, between Broadway Road and I-10 in Tucson, Arizona, but it was never built. This freeway, if built, would have served the downtown area, the University of Arizona campus, and the industrial area between the railroad and I-10; an extension to Tucson International Airport. [13] It first appeared on a Tucson map in 1971. [14] Strong community opposition to freeways in Tucson was a major reason for cancellation of the project on April 16, 1982; the Tucson area has long been opposed to the rapid urban sprawl since.
Future US Bicycle Routes in Arizona include USBR 66, 70, 79, and 90. [15]
Interstate 17 (I-17) is a north–south Interstate Highway located entirely within the US state of Arizona. I-17's southern terminus lies in Phoenix, at I-10/US 60 and its northern terminus is in Flagstaff, at Milton Road north of I-40.
Interstate 19 (I-19) is a north–south Interstate Highway located entirely within the US state of Arizona. I-19 travels from Nogales, roughly 90 meters (300 ft) from the Mexican border, to Tucson, at I-10. The highway also travels through the cities of Rio Rico, Green Valley, and Sahuarita.
State Route 85 is a 128.86-mile-long (207.38 km) state highway in the U.S. state of Arizona. The highway runs from the United States–Mexico border near Lukeville to the north ending at Interstate 10 (I-10) in Buckeye. The highway also intersects I-8 in Gila Bend and serves as a connector between I-8 and I-10 and for travelers between Phoenix and Yuma as well as San Diego. SR 85 between I-10 and I-8, as well as I-8 between SR 85 and I-10 in Casa Grande, is touted as a bypass of the Phoenix area for long-distance travelers on I-10.
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.
U.S. Route 191 is a north–south highway in the Western United States and a spur of parent route U.S. Route 91 that has two segments. The southern segment runs for 1,102 miles (1,773 km) from Douglas, Arizona on the Mexican border to the southern part of Yellowstone National Park. The northern segment runs for 442 miles (711 km) from the northern part of Yellowstone National Park to Loring, Montana, at the Canada–US border. Unnumbered roads within Yellowstone National Park connect the two segments. The highway passes through the states of Arizona, Utah, Wyoming, and Montana.
In the U.S. state of Arizona, Interstate 10 (I‑10), the major east–west Interstate Highway in the United States Sun Belt, runs east from California, enters Arizona near the town of Ehrenberg and continues through Phoenix and Tucson and exits at the border with New Mexico near San Simon. The highway also runs through the cities of Casa Grande, Eloy, and Marana. Segments of the highway are referred to as either the Papago Freeway, Inner Loop, or Maricopa Freeway within the Phoenix area and the Pearl Harbor Memorial Highway outside metro Phoenix.
State Route 84, also known as SR 84, is a 41-mile (66 km) east–west highway in south-central Arizona, with its western terminus at Exit 151 of Interstate 8 and its eastern signed terminus at its junction with State Route 387 and State Route 287 in Casa Grande. An unsigned section, which is mostly maintained by local governments, runs from the SR 287 and SR 387 junction southeast through Arizola and Eloy. East of Eloy, SR 84 is concurrent with the beginning 0.87 miles (1.40 km) of State Route 87 just north of Interstate 10 near Picacho.
State Route 989, also known as SR 989, is an unmarked state highway in Oro Valley, Arizona, that consists of a 2-mile (3 km) stretch of Tangerine Road west of State Route 77.
State Route 77 is a 253.93-mile (408.66-kilometre) long state highway in Arizona that traverses much of the state's length, stretching from its southern terminus at a junction with I-10 in Tucson to its northern terminus with BIA Route 6 at the Navajo Nation boundary just north of I-40.
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. The Arizona stretch is also known as Mule Creek Road.
U.S. Route 60 (US 60) is an east–west United States Highway within Arizona. The highway runs for 369 miles (594 km) from a junction with Interstate 10 near Quartzsite to the New Mexico state line near Springerville. As it crosses the state, US 60 overlaps at various points: I-17, I-10, SR 77, SR 260, US 191, and US 180. Between Wickenburg and Phoenix, the route is known as Grand Avenue. From Tempe to Apache Junction, it is known as the Superstition Freeway.
Arizona State Route 93, abbreviated SR 93, was a state highway in Arizona that existed from 1946 to 1991. The route was co-signed with other highways along nearly all of its route from Kingman to the border at Nogales. SR 93 was the original designation for the highway from Kingman to Wickenburg, which was built in 1946. In 1965, the northern terminus of the state route was moved south to an unnamed desert junction with U.S. Route 89 just north of Wickenburg, and the southern terminus of U.S. Route 93 was moved south to the US 89 junction. The Arizona Highway Department sought U.S. Highway status for SR 93 across the rest of the state, but the proposal was never granted by AASHTO. On December 17, 1984, the SR 93 designation was removed south of the Grand Avenue/Van Buren Street/7th Avenue intersection in Phoenix. The route was completely decommissioned in 1991.
U.S. Route 191 (US 191) is a north–south U.S. Highway in eastern Arizona. The highway runs for 516.50 miles (831.23 km), making it Arizona's longest numbered highway. The highway begins at State Route 80 near Douglas and crosses over the Utah state line near Mexican Water in the Navajo Nation. Between Douglas and Utah, US 191 shares multiple concurrencies with I-10, US 70, US 180, US 60, SR 61, I-40, SR 264, and US 160.
U.S. Route 93 (US 93) is a United States Numbered Highway in the state of Arizona that begins in Wickenburg and heads north to the Nevada state line at the Mike O'Callaghan–Pat Tillman Memorial Bridge. The total length of US 93 in Arizona is 199.38 miles. Between Wickenburg and Interstate 40 (I-40), part of US 93 is designated as the Joshua Forest Scenic Byway. While most of US 93 is a four-lane divided highway, sections of the highway between Wickenburg and I-40 are still narrow two-lane roads, gradually being upgraded to match the rest of the route. As part of a proposal by municipal leaders in Nevada and Arizona, the highway could be replaced by Interstate 11 (I-11).
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.
Below is a list and summary of the former state routes in Arizona, including mileage tables and maps. Between the establishment of Arizona's numbered state highway system in 1927 and the present date, several state routes have been decommissioned. Some state routes were retired as a result of the state relinquishing ownership to local authorities, while others were made extensions of or redesignated as other highways, with some former state routes being upgraded to U.S. Highway or Interstate status.
Interstate business routes are roads connecting a central or commercial district of a city or town with an Interstate bypass. These roads typically follow along local streets often along a former US route or state highway that had been replaced by an Interstate. Interstate business route reassurance markers are signed as either loops or spurs using a green shield shaped and numbered like the shield of the parent Interstate highway.
U.S. Route 80 (US 80), also known as the Ocean-to-Ocean Highway, the Broadway of America and the Jefferson Davis Memorial Highway, was a major transcontinental highway that existed in the U.S. state of Arizona from November 11, 1926, to October 6, 1989. 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.
