Special routes of U.S. Route 93
highway system
Several special routes of U.S. Route 93 exist. In order from south to north they are as follows.
US 93 has two special routes within the state of Arizona.
Hoover Dam temporary route
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. 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.

Why this record matters
The phrase “highway system” supplies a clear boundary for inquiry. It also exposes the unanswered questions: who defined that boundary, when it became stable and which sources sit outside it.
Vocabulary and entity names are the principal evidence signals here, because they determine the precision of every later search. The source revision retrieved here is dated Sep 10, 2026. The linked authority identifier is Q122563657. Authority coordinates are 42.592, -114.460. None of the 1 selected statements returned an explicit reference. The first chronological checks are 2011.
Overview language is designed for orientation and should not be treated as a substitute for the evidence cited beneath it. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
