| Existed | January 1, 2011–present |
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.[1] 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.[2] 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.[3] 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.[4] 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.[1] 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.[5]

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.[1] 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.[6] 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.[7] 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.[8] 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.[9]
