The U.S. state of Arizona's State Routes are usually abbreviated as SR.
The Arizona State Highway system was introduced on September 9, 1927, by the State Highway Commission (formed on August 11 of the same year). It incorporated the new federal aid system and also the U.S. Highway system. The 1927 plan included 27 state routes, most of which were simply dirt roads. Until 1942, the state route marker signs contained a Native American swastika that were used by Navajos, but were removed after the U.S.'s entry into World War II against Nazi Germany which had a reversed swastika as its emblem and became strongly negatively associated with the Nazis.
The modern system was introduced and adopted in the 1950s.
The Arizona Department of Transportation (ADOT) internally recognizes Interstate Highways, U.S. Highways and Arizona Highways as all being separate types of highway designations. State highways within Arizona are referred to as Arizona State Routes or State Routes, with the prefix "SR" being used for abbreviations. [2] [3] ADOT also recognizes seven different types of suffixed routes for the U.S. Highways and State Routes. [4] The recognized suffixes consist of the following with "(Number)" filling in for a numeric designation:
U.S. Highways can also use the same suffixes listed above. Usually the suffixed routes are recognized by ADOT as U.S. Highways. For example, the Alternate route of U.S. Route 89 (US 89) is referred to as U.S. Route 89A (US 89A) instead of State Route 89A (SR 89A). The only exception to this rule is SR 93X, which is a suffixed route of US 93. [1] Suffixed routes for Interstates are a different story. Although the suffixed routes are signed with Interstate green Business shields, they are recognized by ADOT as suffixed State Routes. In the field, Interstate 10 business routes are signed as Interstate 10 Business Loop or Interstate 10 Business Spur, while they are referred to by ADOT as "State Business Route 10" (SR 10B) and "State Route 10 Spur" (SR 10 Spur). The same principle applies with business routes for all other Interstates in Arizona. [3]
Designations listed under Highway Logs and GIS data however, use the Arizona Transportation Information System (ATIS) nomenclature. The ATIS designation for a non-suffixed state route is "S (Number)". The number at the end is always three digits long. As such, all two digit routes are referred to under the ATIS terminology as "S 0(Number)". [3] SR 260 and SR 79 are known under ATIS nomenclature as "S 260" and "S 079" respectively. U.S. Highways replace the prefix "S" used by State Routes under the ATIS nomenclature with "U" while Interstate Highways use the prefix "I". [1] Suffixed routes under ATIS always have the internally applied suffix between the prefix. [3] State Business Route 79 under ATIS nomenclature is referred to as "SB079" and SR 93X is "SX093". [1]

Some routes listed here were eventually constructed using other route numbers.
Currently, the Arizona Department of Transportation recognizes 26 state designated routes under the Parkways, Historic and Scenic Roads Program. Four are Historic Roads, 17 are Scenic Roads and five are Parkways. [7] [8] [9]
Interstate 17 (I-17) is a north–south Interstate Highway 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.
State Route 79, also known as the Pinal Pioneer Parkway, is a 58.40 mi (93.99 km) long state highway in the U.S. state of Arizona. It serves as the main route through the town of Florence, which is also the county seat of Pinal County. Although the highway has been part of the state highway system since at least 1926, it was not designated as SR 79 until 1992. The highway was previously a section of U.S. Route 80 and U.S. Route 89 between Phoenix and Tucson, until both highways were decommissioned in 1977 and 1992 respectively. SR 79 is also the only state highway in Arizona that has a business route, which is SR 79 Business through downtown Florence. SR 79 is also notable for being the location where cowboy western actor Tom Mix died in a car accident on October 14, 1940.
U.S. Route 191 is a spur of U.S. Route 91 that has two branches. The southern branch 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 branch 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 branches. The highway passes through the states of Arizona, Utah, Wyoming, and Montana.
State Route 89A is an 83.85-mile (134.94 km) state highway that runs from Prescott north to Flagstaff in the U.S. state of Arizona. The highway begins at SR 89 in Yavapai County and heads northward from Prescott Valley, entering Jerome. From Jerome, the route then heads to Cottonwood and Clarkdale. The road then continues out to Sedona. The highway is notable for its scenic value as it winds over and through Mingus Mountain as well as passing through Sedona and the Oak Creek Canyon. The route then enters Coconino County soon after leaving Sedona. The highway proceeds to Flagstaff, where it crosses Interstate 17 (I-17) and I-40. The highway ends at I-40 Business in Flagstaff. What is now SR 89A became a state highway in the late 1920s as SR 79. The highway was extended and improved several times through 1938. SR 79 was renumbered to U.S. Route 89A in 1941 and then to SR 89A in the early 1990s.
U.S. Route 89A is a 91.74-mile (147.64 km) north–south auxiliary U.S. highway in southwestern Kane County, Utah and northeastern Coconino County, Arizona in the southwestern United States. The highway is an old routing of U.S. Route 89 from Bitter Springs, Arizona to Kanab, Utah. The state of Arizona has designated this highway the Fredonia-Vermilion Cliffs Scenic Road. The highway is used to access the North Rim of Grand Canyon National Park and is known for the Navajo Bridge. Until 2008, the Utah portion was signed State Route 11. The route provides the only direct road connection between the Arizona Strip and the rest of Arizona.
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 67 is a 43.4 mi (69.8 km) long, north–south state highway in northern Arizona. Also called the Kaibab Plateau – North Rim Parkway, SR 67 is the sole road that links U.S. Route 89A at Jacob Lake to the North Rim of Grand Canyon National Park. Along the route, the road heads through the national park as well as Kaibab National Forest and traverses extensive coniferous forests. The section inside the national park is maintained by the National Park Service (NPS), whereas the section north of the entrance, completely within Kaibab National Forest, is owned by the Arizona Department of Transportation (ADOT). The road was built in the late 1920s and improved through the 1930s. In 1941, the road received its number, and was given its designation as the parkway in the 1980s. The parkway has received designations as a National Forest Scenic Byway as well as a National Scenic Byway.
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.
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 is still a narrow two lane road, 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).
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.
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.
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.
