U.S. Route 93 (US 93) is a United States Numbered Highway in the state of Arizona that begins in Wickenburg and heads north to the Nevada state line at the Mike O'Callaghan–Pat Tillman Memorial Bridge. The total length of US 93 in Arizona is 199.38 miles (320.87 kilometres). Between Wickenburg and Interstate 40 (I-40), part of US 93 is designated as the Joshua Forest Scenic Byway. While most of US 93 is a four-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 by Interstate 11 (I-11).
Most of US 93 from Hoover Dam to Kingman was originally designated as State Route 69 (SR 69) and was later re-designated as the easternmost part of US 466 in 1935. US 93 was extended into Arizona along US 466 to Kingman the same year. Until 1965, the route from US 89 (now SR 89) in Wickenburg to Kingman was designated as SR 93. The remainder of the route to US 60 Wickenburg was part of US 89 until the designation was truncated to Flagstaff, Arizona 1992. US 93 was extended over the former route of US 89, to its current terminus at US 60.
