U.S. Route 93 in the state of Arizona is a United States Numbered Highway that begins in Wickenburg and heads north to the Nevada state line at the Mike O'Callaghan–Pat Tillman Memorial Bridge.
As part of a proposal by municipal leaders in Nevada and Arizona, the highway could be replaced by Interstate 11 (I-11).
The following narrative runs in the descending reference post direction. Arizona has always signed this particular route with its zero mile point located at the Nevada border. Until October 19, 2010, that point was on the crest of Hoover Dam, but ever since has been at the state line along the Mike O'Callaghan–Pat Tillman Memorial Bridge.
The southern terminus of US 93 is located at a junction (rebuilt and relocated between February 2008 and February 2010) with US 60 in Wickenburg, a small town about 50 miles (80 km) northwest of Phoenix. It heads towards the northwest from this junction to an intersection with SR 89 (former US 89) across the Maricopa – Yavapai county line just northwest of town. SR 89 heads northeast to Prescott while US 93 continues its northwesterly heading, as a mainly two-lane highway with passing lanes every few miles. US 93 continues to the northwest to a junction with SR 71 at a diamond interchange southwest of Congress. As it continues to the northwest through this scenic but remote rural area, the highway is known as the Joshua Forest Parkway of Arizona.
The highway widens to four lanes at the Santa Maria River and continues towards the northwest past a junction with SR 97 on its way to the town of Wikieup. Before reaching that town, it passes the tiny settlement of Nothing (just across the Yavapai – Mohave county line) and crosses Burro Creek over dual steel arch bridges about 400 feet (120 m) over the creek.
After passing through Wikieup, US 93 curves north to follow the western edge of the Big Sandy River and one of its tributaries, Knight Creek, on its way toward Interstate 40 (I-40).
At I-40's exit 71, US 93 merges with the Interstate freeway and share the same alignment heading west until they reach Kingman. The two split in Kingman with I-40 heading towards the south to skirt the southern end of the Black Mountains before curving west and into California and US 93 heading northwest towards Las Vegas. A project is currently underway to design and build a free-flowing connection between I-40 and US 93 in western section of Kingman, to avoid the current diamond interchange (exit 48) at Beale Street and the approximately one mile section of congested, undivided roadway that US 93 motorists must navigate before the road widens back into a four-lane divided facility.
Northwest of Kingman and just over Coyote Pass, US 93 has an interchange with SR 68 (exit 67). This junction incorporates a large Commercial Vehicle Inspection Station (CVIS), which ADOT calls a "Port of Entry" (POE), for southbound and eastbound commercial traffic. Highway 68 heads west over the Black Mountains to Davis Dam, Laughlin and Bullhead City (the latter via SR 95), while US 93 continues as a four-lane divided route towards the northwest. Running through the long Detrital Valley, with the Black Mountains to the west and the Cerbat Mountains and then the White Hills to the east, US 93 passes several small settlements in this mostly remote area. As it nears the Nevada state line, it enters the Lake Mead National Recreation Area and climbs over Householder Pass, before crossing into Nevada via the Mike O'Callaghan–Pat Tillman Memorial Bridge over the Black Canyon just downstream of the Colorado River from Hoover Dam.
US 93 continues into Nevada to the cities of Boulder City, Henderson and Las Vegas as part of Interstate 11 (I-11).
The route between Kingman and Hoover Dam first became part of the state highway system in 1934 when it was designated as SR 69.At the time, Hoover Dam was still under construction and the highway did not link to Nevada. The dam was completed the following year in 1935 enabling traffic to cross over the top of the dam. In that year, US 466 was designated over SR 69 from Kingman to Hoover Dam. US 93 was extended south from (then) US 91 at Glendale, Nevada later the same year.
In 1935, Arizona proposed for an extension of US 93 from Kingman to Ash Fork, overlapping US 66, and then south to Phoenix. This proposal was protested by the towns of Aguila and Wickenburg that argued that US 93 should pass through their towns rather than the proposed alignment to the east. The town of Wickenburg contested that a direct routing between Phoenix and Kingman would be 100 miles (161 km) shorter than the routing through Ash Fork and that it would provide a necessary connection between Phoenix, the state capital and the northwestern part of the state. Until 1937, the original proposed extension overlapping US 66 stayed in planning as US 93T. Another route, US 193, was also planned, travelling from Phoenix through Sacaton and Casa Grande before terminating in Picacho. US 193 was briefly reworked under the designation US 93A before the proposal was abandoned in 1937.
On March 23, 1946, what would become the southern leg of US 93 past Kingman was added to the State Highway System as State Route 93.Between 1942 and 1958, the highway was rebuilt and reworked into a suitable highway for an eventual extension of US 93. Though the state wanted US 93 to be extended over all of SR 93 through Phoenix, Casa Grande and Tucson to the Mexico border in Nogales, a southern extension was only accepted by the AASHTO to US 89 north of Wickenburg in 1965. The rest of SR 93 kept its state route designation until 1984.
Until 1992, US 93 ended a short distance north of Wickenburg, Arizona at a junction with U.S. Route 89. When US 89 was decommissioned in the area, the US 93 designation was carried on into Wickenburg.
Between 2006 and 2012, there were several widening projects completed on the section between Wickenburg and Interstate 40.
US 93 (with US 60 to the southeast of Wickenburg) is the shortest route between the fast-growing cities of Las Vegas and Phoenix, two of the largest cities in the Southwest (and is an officially designated portion of the CANAMEX Corridor). Upgrades of US 60 and US 93 to four-lane freeway status are scheduled between Las Vegas and Phoenix; as of 2019, most sections north of the Santa Maria River are already at four-lane expressway status (with some of the newest portions presumably built to Interstate standards) with construction ongoing. This routing is part of Interstate 11 (I-11) which is connected with Interstate 215 (I-215), Interstate 515 (I-515), U.S. Route 95 (US 95) and State Route 564 (former SR 146) at the Henderson Spaghetti Bowl (also known as the "Hender-Bender") interchange in Henderson, Nevada and will connect Interstate 10 in Tonopah.
A segment of this new highway consists of a new route across the Colorado River called the Hoover Dam Bypass. The new crossing is the Mike O'Callaghan–Pat Tillman Memorial Bridge, the first so-called concrete-steel composite arch bridge built in the United States. The bridge is 1,900 feet (579 m) with a 1,080-foot (329 m) main span. The roadway is 840 feet (256 m) above the Colorado River.
The bypass replaced the old section of US 93 that approached and crossed directly over Hoover Dam, which was inadequate by modern standards, because there was one narrow lane in each direction, including several hairpin turns, many dangerous curves and poor sight distances. Also, in the wake of the September 11, 2001 attacks, truck traffic over the Hoover Dam had been diverted south to a river crossing near Laughlin, Nevada via State Route 68, State Route 163 in Nevada and US 95, in an effort to safeguard the dam from hazardous spills or explosions.

US 93 has two special/bannered routes within the state of Arizona.
|State Route 93T|
|Length||2.13 mi :569 (3.43 km)|
State Route 93 Temporary (SR 93T or SR 93X) is an unsigned 2.13-mile (3.43 km) long state highway near the Hoover Dam in Mohave County, Arizona. The route was originally part of the US 93 segment that travelled over Hoover Dam. It was redesignated as SR 93X on January 1, 2011 following the completion of the Hoover Dam Bypass. Unlike most unrelinquished sections of U.S. Highways in Arizona, the old Hoover Dam route was given a state route designation instead of a U.S. Highway one. SR 93X is not related in any way to SR 93, which was the original designation of US 93 between Kingman and Wickenburg, as well as a failed extension of US 93 from Wickenburg to Nogales. The route begins at the Nevada state line on the Hoover Dam, heading southeast, before switch-backing up a hillside at the southeastern end of the dam. ADOT ownership of SR 93X begins exactly 1-mile (1.6 km) southeast of the Hoover Dam on Kingman Wash Access Road near the Arizona side Hoover Dam Lookout. The route proceeds southeasterly along Kingman Wash Access Road, crossing under US 93 less than a mile from the lookout. Approximately 2.13 miles (3.43 km) from its western terminus, SR 93 arrives at a freeway interchange with US 93, which also serves as its eastern terminus. Currently, the majority of SR 93X is gated off to public traffic. The western first 1.01 miles (1.63 km) of the route and Arizona side of the Hoover Dam are still accessible to public traffic, but can only be reached via US 93, SR 172 and Hoover Dam Access Road through Nevada. There is currently no open road for motorists to leave the Arizona side of the Dam, whilst remaining in the state.
The entire route is in Mohave County.

U.S. Route 93 Spur (US 93 Spur) is a 0.38-mile (0.61 km) long unsigned spur route of US 93 in Kingman, Arizona. Originally a small section of US 66, it became part of the Kingman I-40 Business Loop (I-40 BL) on October 26, 1984 upon the decommissioning of the former highway in Arizona. The majority of I-40 BL was retired to the city of Kingman in 2002, with two sections, each less than a mile long, remaining under ADOT ownership at I-40 exits 48 and 53 respectively. On September 18, 2009, the I-40 BL designation was decommissioned. The two remaining segments owned by ADOT became a minor southwestern extension of SR 66 and a new route designated US 93 Spur. US 93 Spur begins at an intersection with I-40 and US 93 at Beale Street and I-40 exit 48. The unsigned spur route continues west on Beale Street, ending about three blocks east of I-40 and US 93 at an intersection with "Route 66", Grandview Avenue and Beale Street in front of Locomotive Park.
The entire route is in Kingman, Mohave County.

Interstate 17 (I-17) is a north–south Interstate Highway located entirely within the U.S. state of Arizona. I-17's southern terminus lies within Phoenix, at Interstate 10, and its northern terminus is in Flagstaff, at Interstate 40. The majority of I-17 is known as the Arizona Veterans Highway. In the Phoenix metropolitan area, it is mostly known as the Black Canyon Freeway, however the southern 4.16 miles (6.69 km) is part of the Maricopa Freeway. The portion of the highway south of Cordes Lakes was built along the alignment of SR 69, while the northern part was built along old SR 79's alignment. I-17 is one of the most scenic Interstate Highways as it gains more than a mile in altitude between Phoenix at 1,117 feet (340 m) and Flagstaff at 7,000 feet (2,100 m). The highway features several scenic view exits along its route that overlook the many mountains and valleys found in northern Arizona.
U.S. Route 93 (US 93) is a major north–south United States highway in the western United States. The southern terminus is at US 60 in Wickenburg, Arizona. The northern terminus is at the Canada–US border north of Eureka in Lincoln County, Montana, where the roadway continues into Roosville, British Columbia, as Highway 93. Major cities that US 93 travels through include: Las Vegas, Nevada, Twin Falls, Idaho, Missoula, Montana and Kalispell, Montana.
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 lost his life in a car accident on October 14, 1940.
State Route 89 (SR 89) is a 104.53-mile (168.22 km) state highway in the U.S. state of Arizona. It is part of the former route of U.S. Route 89 (US 89) throughout the state.
Interstate 11 (I-11) is a north-south Interstate Highway tentatively planned to run from Nogales, Arizona, to the vicinity of Reno, Nevada, generally following the current routes of Interstate 19 (I-19), I-10, U.S. Route 93 (US 93) and US 95. Currently, the only open section of I-11 is a 22.845-mile-long (36.765 km) freeway running predominantly northwest–southeast in the U.S. state of Nevada that currently follows US 93 between the Arizona state line and Henderson. Planners anticipate upgrading two existing highway segments to carry future I-11: US 93 in Arizona from Wickenburg to the Nevada state line on the Mike O'Callaghan–Pat Tillman Memorial Bridge over the Colorado River and US 95 in Nevada from the Las Vegas Valley to Tonopah. Outside of these sections, an alignment for I-11 has yet to be determined; however, a number of corridor alternatives have been identified for further study and refinement.
The CANAMEX corridor is a series of improvements to freeways and other transportation infrastructure linking Canada to Mexico through the United States. The corridor was established under the North American Free Trade Agreement. Currently the corridor is defined by a series of highways. However, the corridor is also proposed for use by railroads and fiber optic telecommunications infrastructure.
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.
Arizona State Route 74 (SR 74), locally known as the Carefree Highway, is a state highway in central Arizona that stretches east to west from its junction with U.S. Route 60 (US 60) just south of Wickenburg to its junction with Interstate 17 (I-17) in North Phoenix. It serves Lake Pleasant Regional Park and serves as a northern bypass around the often congested stretches of US 60 through the northwest suburbs of the Phoenix metropolitan area. From end to end, it is 30.4 miles (48.9 km) long.
State Route 587, also known as SR 587, is a state highway in south-central Arizona that travels from its junction with State Route 87 just south of Sun Lakes directly south to Interstate 10 in Bapchule. The entire highway is just six miles (10 km) long, traveling entirely within the Gila River Indian Reservation, and serves as a shortcut from the far southern suburbs of the Phoenix metropolitan area to Interstate 10.
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.
Interstate 40 (I-40) is an east–west Interstate Highway that has a 359.11-mile (577.93 km) section in the U.S. state of Arizona, connecting sections in California and New Mexico. The section throughout the entire route in Arizona is also known as the Purple Heart Trail to honor those wounded in combat who have received the Purple Heart. It enters Arizona from the west at a crossing of the Colorado River southwest of Kingman. It travels eastward across the northern portion of the state connecting the cities of Kingman, Ash Fork, Williams, Flagstaff, Winslow, and Holbrook. I-40 continues into New Mexico, heading to Albuquerque. The highway has major junctions with U.S. Route 93 — the main highway connecting Phoenix and Las Vegas, Nevada — in Kingman and again approximately 22 miles (35 km) to the east and Interstate 17 — the freeway linking Phoenix to northern Arizona — in Flagstaff.
U.S. Route 89 in the U.S. state of Arizona is a U.S. Highway that begins in Flagstaff and heads north to the Utah border northwest of Page.
In the U.S. state of Nevada, U.S. Route 93 is a major United States Highway traversing the eastern edge of the state. The highway connects the Las Vegas area to the Great Basin National Park, and provides further connections to Ely and Wells. US 93 also provides the majority of the most direct connection from the major metropolitan areas of Las Vegas and Phoenix to the Boise, Idaho Metropolitan Area with a final connection to Boise via Interstate 84 from Twin Falls, Idaho.
