U.S. Route 93 (US 93) is aUnited States Numbered Highway in the state ofArizona that begins inWickenburg and heads north to theNevada state line at theMike O'Callaghan–Pat Tillman Memorial Bridge. The total length of US 93 in Arizona is 199.38 miles (320.87 kilometres). Between Wickenburg andInterstate 40 (I-40), part of US 93 is designated as theJoshua Forest Scenic Byway. While most of US 93 is afour-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 byInterstate 11 (I-11).
Most of US 93 from Hoover Dam to Kingman was originally designated asState Route 69 (SR 69) and was later re-designated as the easternmost part ofUS 466 in 1935. US 93 was extended into Arizona along US 466 toKingman the same year. Until 1965, the route fromUS 89 (nowSR 89) in Wickenburg to Kingman was designated asSR 93. The remainder of the route toUS 60 Wickenburg was part of US 89 until the designation was truncated toFlagstaff, Arizona 1992. US 93 was extended over the former route of US 89, to its current terminus at US 60.
The southern terminus of US 93 is located at a junction (rebuilt and relocated between February 2008 and February 2010) withUS 60 inWickenburg, a small town about 50 miles (80 km) northwest ofPhoenix. It heads towards the northwest from this junction to an intersection withSR 89 (former US 89) across theMaricopa –Yavapai county line just northwest of town. SR 89 heads northeast toPrescott 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 withSR 71 at a diamond interchange southwest ofCongress. As it continues to the northwest through this scenic but remote rural area, the highway is known as theJoshua Forest Parkway of Arizona.[2]
The highway widens to four lanes at theSanta Maria River and continues towards the northwest past a junction withSR 97 on its way to the town ofWikieup. Before reaching that town, it passes the tiny settlement ofNothing (just across the Yavapai –Mohave county line) and crosses Burro Creek over dualsteel arch bridges, which are located about 400 feet (120 metres) above the intermittent waterway.[2]
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 towardInterstate 40 (I-40).[2]
At I-40's exit 71, US 93 merges with the Interstate freeway and shares the same alignment heading west until they reachKingman. 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 intoCalifornia and US 93 heading northwest towardsLas Vegas. A project is currently underway to design and build a free-flowing connection between I-40 and US 93 in the 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.[2]
Northwest of Kingman and just over Coyote Pass, US 93 has an interchange withSR 68 (exit 67). This junction incorporates a large Commercial Vehicle Inspection Station (CVIS), whichADOT calls a "Port of Entry" (POE), for southbound and eastbound commercial traffic. Highway 68 heads west over the Black Mountains toDavis Dam,Laughlin, andBullhead City (the latter viaSR 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 most remote area. As it nears theNevada state line, it enters theLake Mead National Recreation Area and climbs over Householder Pass, before crossing into Nevada via the Mike O'Callaghan–Pat Tillman Memorial Bridge over theBlack Canyon just downstream of theColorado River fromHoover Dam.[2]
US 93 continues into Nevada to the cities ofBoulder City,Henderson and Las Vegas as part of Interstate 11 (I-11) and as US 93 north of them.[2][3]

The route between Kingman and Hoover Dam first became part of the state highway system on June 18, 1934, when it was designated as SR 69.[5] 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.[6] In that year,U.S. Route 466 (US 466) was designated over SR 69 from Kingman to Hoover Dam. US 93 was extended south from (then) US 91 atGlendale, Nevada later the same year.[7] Although the US 466 designation had been approved by theAmerican Association of State Highway Officials (AASHO) from Glendale to Kingman on October 9, 1933, theArizona State Highway Department had waited until May 16, 1935, before retiring SR 69 and re-designating it as US 466.[8][9] US 466 was joined by US 93 on June 17, 1935, after AASHO approved an extension of the latter route from US 91 north ofLas Vegas, Nevada to Kingman.[10]
In 1935, Arizona proposed an extension of US 93 from Kingman toAsh Fork, overlappingUS 66, and then south toPhoenix. This proposal was protested by the towns ofAguila andWickenburg 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 originally proposed extension overlapping US 66 stayed in planning asUS 93T. Another route,US 193, was also planned, traveling from Phoenix throughSacaton andCasa Grande before terminating in Picacho. US 193 was briefly reworked under the designation US 93A before the proposal was abandoned in 1937.[7]
On March 23, 1946, what would become the southern leg of US 93 past Kingman was added to the State Highway System asState Route 93.[11] Between 1942 and 1958, the highway was rebuilt and reworked into a suitable highway for an eventual extension of US 93.[12][7] Though the state wanted US 93 to be extended over all of SR 93 through Phoenix, Casa Grande andTucson to theMexico border inNogales, a southern extension was only accepted by theAASHTO to US 89 north of Wickenburg in 1965.[7] The rest of SR 93 kept its state route designation until 1984.[13] On December 3, 1971, the entirety of US 466 was decommissioned, upon request by the states of Arizona and Nevada. This left US 93 as the sole designation between Kingman and Las Vegas.[14]
Until 1992, US 93 ended a short distance north ofWickenburg, Arizona at a junction withU.S. Route 89. When US 89 was decommissioned in the area, the US 93 designation was carried on into Wickenburg.
In 2005, construction started on a new route across theColorado 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. It opened to traffic in 2010.
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 severalhairpin turns, many dangerous curves, and poor sight distances. Also, in the wake of theSeptember 11, 2001 attacks, truck traffic over the Hoover Dam had been diverted south to a river crossing nearLaughlin,Nevada viaState Route 68,State Route 163 in Nevada and US 95, to safeguard the dam from hazardous spills or explosions.
Starting in 2006, several widening projects were completed on the section between Wickenburg and Interstate 40, with the ultimate goal of improving the entire route to a four-lane divided highway.[15]
In 2010, the "Interim Wickenburg Bypass" was completed, re-aligning US-93 to the east of the downtown, and constructing two roundabouts and a bridge to relieve congestion in the area.[15] In 2024, an additional four roundabouts in the town were constructed, extending the so-called bypass north.[16]
In 2024, construction started on a direct system interchange with I-40 in Western Kingman to eliminate the current bottleneck at Beale Street. It is expected to be finished in 2027.[17]

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 theSouthwest, and is an officially designated portion of theCANAMEX Corridor. While the bulk of US 93 through Arizona has been widened to four lanes, some portions of the corridor are not built to Interstate Highway standards, as there are scattered at-grade intersections, substandard roadway and shoulder widths, median crossovers, and other deficiencies. Part of these dual roadways are repaved, restriped sections of very old parts of US 93. This routing is part ofInterstate 11 (I-11), which includes the formerInterstate 515 (I-515) and runs concurrent withU.S. Route 95 (US 95) throughoutLas Vegas,Nevada. Future plans for the extension of I-11 call for the route to continue following US 93 all the way to its southern terminus inWickenburg, Arizona.[18] Phase 4 of the US 93 Corridor Improvement Project will finish what was started in 1998 and connect the four sections of the divided highway to Wickenburg, allowing more traffic on these congested roads. US 93 will be co-signed as I-11 once it is built to Interstate standards. US 93 from its southern terminus to north of Las Vegas will most likely be decommissioned afterwards.
Although seen as beneficial to some people, the controversial plan to build I-11 in Arizona as a whole is still receiving fierce pushback and conservation groups are currently suing bothADOT andFHWA over the construction of that route. In 2025, planning for the freeway bypass fromI-19 inSahuarita to US 93 in Wickenburg was stopped per court order.
Mileposts start at theNevada state line and are based on the mileposts of formerSR 69 andUS 466.

| Existed | January 1, 2011–present |
State Route 93 Temporary (SR 93T orSR 93X) is an unsigned 2.13-mile (3.43 km) long state highway near theHoover Dam inMohave County.[2] 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 theHoover 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.[21] SR 93X is not related in any way toSR 93, which was the original designation of US 93 betweenKingman andWickenburg, as well as a failed extension of US 93 from Wickenburg toNogales.[7] The route begins at theNevada state line on the Hoover Dam, heading southeast, before switch-backing up a hillside at the southeastern end of the dam.[22] 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.[2] 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 93X 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, I-11,SR 172 and Hoover Dam Access Road through Nevada. There is currently no open road for bicycles, pedestrians and vehicles to leave the Arizona side of the Dam, whilst remaining in the state.[23]
The entire route is inMohave County.

U.S. Route 93 Spur (US 93 Spur) is a 0.38-mile (0.61 km) long unsigned spur route of US 93 inKingman.[2] Originally a small section ofUS 66, it became part of the KingmanI-40 Business Loop (I-40 BL) on October 26, 1984, upon the decommissioning of the former highway in Arizona.[24] 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.[25] On September 18, 2009, the I-40 BL designation was decommissioned. The two remaining segments owned by ADOT became a minor southwestern extension ofSR 66 and a new route designated US 93 Spur.[26] 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 east on Beale Street, ending about three blocks east of I-40 and US 93, at an intersection with Ella's Place, Grandview Avenue, and Beale Street in front of Locomotive Park.[27]
The entire route is inKingman,Mohave County.
