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.

State Route 62
Chloride Spur
Location	Grasshopper Junction to Chloride
Length	3.79 mi (6.10 km)
Existed	1936–1971

A map of SR 62, highlighted in red.

State Route 62 (SR 62) was a state highway in northwestern Arizona running a total of 3.50 miles (5.63 kilometres) from US 93 and US 466, north of Kingman to the mining town of Chloride.^[1] SR 62 was designated on May 5, 1936, coinciding with the extension of US 466 and US 93 across the Hoover Dam into Arizona. Despite the separate State Route designation from US 93/US 466, the Arizona State Highway Department considered SR 62 to be the "Chloride Spur" of both U.S. Highways.^[2] It was deleted from the state highway system on July 23, 1971 because of the closure of the mine in Chloride.^[3] The road is still in use today as Mohave County Road 125.^[4]

The entire route was in Mohave County.

Existed	1961–1981

State Route 63 (SR 63) was a 136.64-mile (220-kilometre) long state highway in northeastern Arizona servicing the Navajo Nation.^[10] SR 63 was designated on January 10, 1961, along a route from U.S. Route 66 (US 66) in Chambers to the reservation boundary of the Navajo Nation.^[11] On December 14, 1962, SR 63 was extended north of the reservation boundary to SR 264 in Ganado.^[12] On June 15, 1970, the route was further extended north over Navajo Route 8 and Navajo Route 17 to US 164, which became part of US 160 later that year.^[13] SR 63 was decommissioned on May 11, 1981, when the route became part of US 191.^[14]

Location	Tempe to Mesa
Length	3.02 mi (4.86 km)
Existed	1955–1979

A map of SR 69T, final alignment highlighted in red, original extent highlighted in transparent red.

State Route 69T or State Route 69 Temporary (SR 69T) was a 3.02-mile (4.86-kilometre) long temporary state route in the Phoenix metropolitan area of Arizona.^[18] SR 69T was originally designated on January 10, 1955, running from McDowell Road and Grand Avenue (US 60, US 70 and US 89) south on 19th Avenue past a junction with US 80 at Buckeye Road, then proceeding east on Baseline Road to SR 87 and SR 93 at Country Club Drive in Mesa.^[19] The primary purpose for the existence of SR 69T was to serve as a detour and temporary corridor for future I-17 and I-10 traffic between Grand Avenue and Baseline Road, while both Interstates were under construction.^[20][21] Although SR 69T never touched its parent route, SR 69, the latter route used to run immediately parallel with or close to part of SR 69T, with the two routes being connected via Grand Avenue or Buckeye Road.^[22][19][23]

In 1957, the Black Canyon Freeway, a section of I-17 that had previously run from Durango Street to McDowell Road, was extended north along SR 69 on 23rd Avenue to a new interchange with Grand Avenue.^[24] Following the opening of I-17 between Grand Avenue and McDowell Road, SR 69T was truncated south to end at US 80 (Buckeye Road) on June 17, 1957.^[21] On March 12, 1963, SR 69T was further truncated in the west from US 80 to 16th Street and Baseline Road, then extended north along 16th Street to connect with I-10 at 16th Street.^[25][26] The newly constructed section of I-10 from I-17 at Durango Street to 16th Street, known as the Maricopa Freeway, effectively replaced the need for SR 69T between US 80 and 16th Street.

By 1965, construction had begun on I-10 east of 16th Street towards Baseline Road.^[1] Another section of I-10 was completed south of SR 69T (Baseline Road) in Tempe between 1967 and 1968.^[27] I-10 was completed between 16th Street and Baseline Road with the opening of the Broadway Curve in 1968.^[28] Between 1965 and 1970, SR 69T was truncated and rerouted to begin at 40th Street and I-10, following 40th Street south to Baseline Road.^[1][20] On July 17, 1970, SR 69T was decommissioned west of I-10 and Baseline Road in Tempe, completely removing the designation from Phoenix.^[20] In 1976, SR 69T was truncated to its final western terminus at Price Road and Baseline Road.^[29] The remainder of SR 69T was decommissioned from Price Road to SR 87/SR 93 on August 13, 1979.^[30]

The entire route was in Maricopa County.

State Route 74
Location	Ehrenberg to Wickenburg
Length	111.20 mi (178.96 km)
Existed	1927–1931

State Route 74 (SR 74) was a 111.20-mile (178.96-kilometre) state highway in Arizona.^[31][2] SR 74 was originally commissioned on September 9, 1927, as one of the original state highways, originally starting at the Colorado River in Ehrenberg and ending halfway between Ehrenberg and Wickenburg near Love.^[32] By 1928, the highway had been extended east to US 89 in Wickenburg. At this time, SR 74 was entirely an ungraded dirt road.^[33] A small section of SR 74 from Ehrenberg traveling a few miles east had been graded and given an improved surface by 1929.^[34] The road was graded between Wickenburg and a point immediately west of Salome by 1930.^[31] On June 13, 1931, SR 74 was decommissioned after becoming part of an extension of US 60 to Los Angeles, California.^[35] The designation was later re-used when the current SR 74 was designated in 1962.^[36]

State Route 76
Location	Benson–Pomerene Peppersauce Wash– SR 77
Length	11.16 mi[38] (17.96 km)
Existed	1962–1988

State Route 76 (SR 76) consisted of two discontinuous sections of highway between Benson and SR 77, both of which gave SR 76 a total length of 11.16 miles (17.96 km).^[38] The highway was originally established between the San Manuel Copper Mine and the adjoining town of San Manuel, on December 28, 1962.^[39][40] A small segment of Pomerene Road near Benson was later added to SR 76, creating the discontinuous gap. This was part of a proposed extension of the highway from San Manuel to Benson.^[41][42] This extension was originally to be designated as SR 176, before it was changed into an extension of SR 76.^[43][44] Construction had also begun on the extension south of San Manuel, but was ultimately never completed, with the last constructed segment being abandoned halfway through construction, never being paved or open to traffic. However, one part of this extension is open and currently serves as a link from San Manuel to San Pedro River Road.^[45][46] The section of highway between SR 77 and the copper mine was decommissioned in 1974.^[40][47][48] On December 16, 1988, SR 76 was entirely decommissioned as a state highway, with any land and right of way acquired for the incomplete Benson extension also being sold off.^[47]

Arizona has had three state routes designated SR 79 at different time periods, one of which is still currently designated.

State Route 79
Location	Prescott to Flagstaff
Length	85.30 mi (137.28 km)
Existed	1927–1940

State Route 79 (SR 79) was a 85.30-mile (137.28-kilometre) long state route between Prescott and Flagstaff.^[2] The first route to use the SR 79 designation was commissioned on September 9, 1927, as part of the original state highways from U.S. Route 89 (US 89) in Prescott to Jerome.^[32] By 1928, it was extended northeast to US 66 Flagstaff. This allowed SR 79 to act as a shorter route between Prescott and Flagstaff for motorists, rather than needing to take US 89 and US 66 on a longer route through Ash Fork. Only a section of the road from Prescott to Cottonwood was graded and had an upaved surfacing, with the remainder being an unimproved dirt road.^[33] The entire route was paved by 1939.^[49] On June 3, 1940, the American Association of State Highway and Transportation Officials approved a request by the state of Arizona to redesignate the entirety of SR 79 as US 89 Alternate (US 89A).^[50] When the highway reverted to a state route in 1993, it kept the 89A designation.

State Route 79
Location	Flagstaff
Length	1.51 mi (2.43 km)
Existed	1950–1993

A map of SR 79, highlighted in red.

State Route 79 (SR 79) was a 1.51-mile (2-kilometre) long state route located entirely within the city of Flagstaff.^[51] SR 79, being the second route to carry the designation in Arizona, was originally designated on May 19, 1950, from Camp Verde to SR 69 at Cordes Junction.^[52] In 1955, it was extended to US 89A south of Flagstaff over a county highway as SR 79T. SR 79T was to exist only until the proposed federal aid route between Camp Verde and Flagstaff was completed.^[53] In 1962, SR 79's new routing was complete, and part of the temporary routing was abandoned back to county ownership.^[54][55] The remainder of SR 79T was retired in 1964.^[56] SR 79 was extended north along US 89A to US 66 and US 89 in 1964.^[57]

On April 24, 1970, approval was given to remove the SR 79 designation and signage between Cordes Junction and Interstate 40 (I-40) in Flagstaff, as this section of the route was replaced by or slated to be rebuilt into I-17.^[58] However, sections not built to Interstate standards were still marked as SR 79 on the official 1971 state highway map.^[59] By 1975, the southern terminus of SR 79 had been truncated to the northern terminus of I-17. Both termini were located at the I-17 interchange with I-40.^[27] From 1975 to 1992, SR 79 continued north along the same roadway that had been I-17 to a junction with US 89A. SR 79 then ran entirely concurrent with US 89A from just north of the I-17 and I-40 interchange to US 66 and US 89 (which was later replaced by I-40 Business).^[27][60] The third incarnation of SR 79 was designated on August 21, 1992, while the second SR 79 still existed. The third incarnation was located between SR 77 and US 60, replacing a section of US 89, which had been truncated to Flagstaff.^[61] The remainder of the second SR 79 was decommissioned on March 19, 1993.^[62]

The entire route was in Flagstaff, Coconino County.

Arizona had two state routes designated SR 81 at different time periods.

State Route 81
Location	Douglas to Sanders
Length	376.30 mi (605.60 km)
Existed	1927–1938

State Route 81 (SR 81), was a 376.30-mile (605.60-kilometre) long state highway in eastern Arizona.^[49][2] SR 81 served as one of the original state routes, designated on September 9, 1927.^[2] The route was originally a major highway stretching from U.S. Route 80 (US 80) in Douglas to US 180 (later US 70) in Safford.^[63]

In 1936, SR 81 was extended north to US 66 in Sanders. Between, Safford and the southern terminus of SR 71 near Solomonsville, SR 81 now shared a concurrency with US 70. SR 71 was decommissioned entirely, being replaced by SR 81 from US 70 to US 60T/SR 73 in Eagar. Starting in Alpine, SR 81 ran concurrently with US 260 to St. Johns. North of Eagar, SR 81 ran concurrently with US 60T to Springerville. SR 81 followed SR 61 north from St. Johns for 30 miles (48 kilometres), then ran alone on a newly designated state highway to US 66 in Sanders.^[37][64]

The entire route was approved as an extension of US 666, which was approved by the American Association of State Highway Officials (AASHTO) on December 4, 1938.^[65] As a result, SR 81 was decommissioned, with US 666 becoming the sole designation of the route between Douglas and Sanders.^[49] The Arizona portion of US 666 would later be redesignated as an extension of US 191 in June 1992.^[66]

Length	6.08 mi[70] (9.78 km)
Existed	1951–1963

A map of SR 84A in 1958. The route is highlighted in red.

State Route 84A (SR 84A) was a branch of State Route 84 between Tucson and South Tucson beginning at SR 84 on Casa Grande Highway (now West Miracle Mile) and continuing south along what is now I-10 to an interchange with US 80, US 89 and SR 84 at 6th Avenue and Benson Highway.^[71] SR 84A was also known by the names Tucson Limited Access Highway and Tucson Freeway.^[72][73] Construction on SR 84A was approved in 1948, but wasn't started until December 27, 1950.^[72][74] Funding was initially obtained through a 1948 Tucson city bond issue.^[75]

SR 84A was opened in segments, with the first section between SR 84 and Congress Street opening on December 20, 1951.^[76] The Santa Cruz River through Tucson was diverted into a man made channel during the construction of SR 84 to keep the river from flooding the new highway.^[77] Though incomplete, all segments of the highway were opened to traffic by 1956.^[23] SR 84A was added to the Interstate Highway System in 1958 and work immediately began on converting the incomplete limited access highway into a full section of I-10. Conversion work was completed in 1961, officially making SR 84A a section of I-10.^[75] The SR 84A designation was decommissioned in favor of I-10 on October 11, 1963.^[78]

The following represents SR 84A as it was in 1958, shortly before conversion work began to turn it into I-10. The entire route was in Pima County.

A map of SR 89L, highlighted in red.

State Loop Route 89 (SR 89L) was a 3.41-mile (5-kilometre) long state highway in Page, Arizona.^[67] SR 89L was first commissioned through Page on February 21, 1968.^[81] Although the number indicated that SR 89L was a loop for SR 89, it served as a business loop for U.S. Route 89 (US 89) through the town of Page.^[82] It did not intersect SR 89. Moreover, it was the only Arizona state highway known to have used the "L" suffix.^[67] The route followed Lake Powell Boulevard through Page, intersecting with Coppermine Road, which was a former section of SR 98.^[83][67] SR 89L was removed from the state highway system on December 14, 2001.^[84]

State Route 93
Location	Wickenburg to Nogales
Length	247.13 mi[10] (397.72 km)
Existed	1946–1985

State Route 93 (SR 93) was a state highway in Arizona that existed from 1946 to 1985. The route was cosigned with other highways along nearly all of its route from Kingman to the border at Nogales. State Route 93 was the original designation for the highway from Kingman to Wickenburg, which was built in 1946. At some point prior to 1964 the northern terminus of the state route was moved south to the unnamed desert junction with U.S. 89 just north of Wickenburg, and the southern terminus of U.S. 93 was moved route south to the U.S. 89 junction. At that junction a driver would pass from U.S. 93 onto State Route 93. When U.S. 89 was reduced to state highway status in the 1990s, U.S. 93's southern terminus was moved south a few miles to U.S. 60 in Wickenburg. For some unknown reason, the Arizona Highway Department either never sought, or was never granted, U.S. Highway status for Route 93 across the rest of the state.

State Route 153
Sky Harbor Expressway
Location	Phoenix
Length	2.12 mi[85] (3.41 km)
Existed	1985–2007

State Route 153, also known as the Sky Harbor Expressway, was a state highway in Maricopa County, Arizona, that used to run from the intersection of 44th Street and Washington Street in Phoenix south to University Drive.^[85] It was a controlled access arterial expressway, with a speed limit of 45 mph (72 km/h), lower than the standard freeway speed of 65 mph (105 km/h). SR 153 was also a north–south route that skirts the eastern edge of Phoenix Sky Harbor International Airport, and along with SR 143, SR 153 served a portion of East Valley residents with access to the airport. The majority of them used SR 143 instead, because of its quick access to and from Interstate 10 and Loop 202. SR 153 did, however, provide a direct link between east Phoenix, such as office developments in the Southbank commercial project, and the city of Tempe. It was decommissioned as a state highway and transferred to the city of Phoenix on October 19, 2007.^[86]

State Route 789
Location	Nogales to the New Mexico state line
Existed	1956–1965

State Route 789 was a state highway in the eastern part of the state of Arizona, starting in the town of Nogales and ending at the New Mexico state line near Gallup on old U.S. Route 66 (presently Interstate 40). The route was cosigned with other routes, including U.S. Route 89 North from Nogales to Tucson, U.S. Route 80/U.S. Route 89 north from Tucson to U.S. Route 60 and U.S. Route 70 at Florence Junction, east on 60/70 to Globe and then 60 past Show Low to State Route 61, then east on 61 to U.S. 666 north of Springerville, where it overlapped U.S. 666 and U.S. 66 to Gallup N.M. It first appeared on an Arizona state map in 1956 and was decommissioned around 1965 when the route was decertified.

State Route 789 was a leg of a proposed U.S. 789, a number proposed for the Canada to Mexico Highway. Boosters wanted to route this new highway marked from Nogales, Arizona, north to Sweetgrass, Montana. Since the highway was to be routed along existing U.S. highways for the majority of its journey, an application for this route to be signed as a U.S. highway was denied by AASHTO. One remnant of U.S. 789 in Wyoming remains to this day as Wyoming 789.

U.S 789 was to continue north with U.S. 666 through Farmington into Cortez, Colorado. U.S. 160 and State Route 789 turned east to serve Durango.

At Durango, State Route 789 turned north again, this time via U.S. 550. At Montrose, State Route 789 followed U.S. 50 northwest to Grand Junction, then turned east again, this time via U.S. 6-24 (now Interstate 70). At Rifle, State Route 789 turned north along Colo. 13, which took State Route 789 to its present Wyoming routing at Baggs. State Route 789 is still designated through Wyoming today; see the routing section above. North of Frannie, State Route 789 continued into Montana via U.S. 310 to Laurel. State Route 789 turned east via U.S. 10-212 (now Interstate 90 and U.S. 212) into Billings. U.S. 87 and State Route 789 merged from Billings all the way to Great Falls, which brought SR 789 westward again. Then State Route 789 turned due north along U.S. 91 (now I-15) to its end at Sweetgrass, Montana.

As the Association of American State Highway Administrators never approved the concept of U.S. 789, all the state route segments started to disappear, with State Route 789 decertified about 1965.

The only stand-alone section of putative U.S. 789 is a section of Wyoming 789.
