U.S. state constituent political entity of the United States

In the United States, a state is a constituent political entity, of which there are currently 50. Bound together in a political union, each state holds governmental jurisdiction over a separate and defined geographic territory and shares its sovereignty with the federal government. Due to this shared sovereignty, Americans are citizens both of the federal republic and of the state in which they reside. State citizenship and residency are flexible, and no government approval is required to move between states, except for persons restricted by certain types of court orders. Four states use the term commonwealth rather than state in their full official names.

Arizona state of the United States of America

Arizona is a state in the southwestern region of the United States. It is also part of the Western and the Mountain states. It is the sixth largest and the 14th most populous of the 50 states. Its capital and largest city is Phoenix. Arizona shares the Four Corners region with Utah, Colorado, and New Mexico; its other neighboring states are Nevada and California to the west and the Mexican states of Sonora and Baja California to the south and southwest.

Wickenburg, Arizona Town in Arizona, United States

Wickenburg is a town primarily located in Maricopa County, Arizona, United States, with a portion in neighboring Yavapai County. According to the 2010 census, the population of the town is 6,363.


As part of a proposal by municipal leaders in Nevada and Arizona, the highway could be replaced by Interstate 11 (I-11).

Interstate 11 (I-11) is a north-south Interstate Highway tentatively planned to run from Nogales, Arizona, to Reno, Nevada, along the current routes of I-19, I-10, 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 U.S. Route 93 (US 93) and U.S. Route 95 (US 95) between the Arizona state line and Henderson. The bulk of the route is still in the early discussion and planning stages. Except for the portion between Wickenburg, Arizona to Hoover Dam, which will run on an upgraded US 93, an exact route for I-11 has yet to be determined. A number of corridor alternatives have been identified for further study and refinement.

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.

Hoover Dam hydroelectric dam on the Colorado River, United States

Hoover Dam is a concrete arch-gravity dam in the Black Canyon of the Colorado River, on the border between the U.S. states of Nevada and Arizona. It was constructed between 1931 and 1936 during the Great Depression and was dedicated on September 30, 1935, by President Franklin D. Roosevelt. Its construction was the result of a massive effort involving thousands of workers, and cost over one hundred lives. Originally known as Boulder Dam from 1933, it was officially renamed Hoover Dam, for President Herbert Hoover, by a joint resolution of Congress in 1947.

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.

U.S. Route 60 in Arizona highway in Arizona

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.

Phoenix, Arizona State capital city in Arizona, United States

Phoenix is the capital and most populous city of Arizona, with 1,626,000 people. It is also the fifth most populous city in the United States, and the most populous American state capital, and the only state capital with a population of more than one million residents.

Arizona State Route 89 highway in Arizona

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.

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.

Santa Maria River (Arizona) river in the United States of America

The Santa Maria River is an intermittent stream located in western Arizona. It is a primary tributary of the Bill Williams River and one of the main sources of inflow for Alamo Lake. The river forms a portion of the boundary between Mohave and La Paz counties.

State Route 97(SR 97) is a 10.91-mile-long (17.56 km) state highway in the U.S. state of Arizona. It runs from U.S. Route 93 northwest of Congress northeast to SR 96 southeast of Bagdad. The road was built by the late 1930s and improved during the late 1940s. Established as a state route in 1962, SR 97 was paved in the early 1970s. In 2000, the highway was officially added to the State Highway system.

Wikieup, Arizona Place in Arizona, United States

Wikieup is a small unincorporated community located on U.S. Route 93 in Mohave County, Arizona. It is located approximately 32 miles (51 km) south of Interstate 40 using U.S. Route 93 and approximately 124 miles (200 km) northwest of Phoenix, Arizona. In 2000, the population of Wikieup's ZCTA was 305.

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).

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 Arizona is also known as the Purple Heart Trail. 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.

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). [1] [3]


The route between Kingman and Hoover Dam first became part of the state highway system in 1934 when it was designated as SR 69. [4] 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. [5] 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 in 1951. [6]

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. [6]

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. [7] Between 1942 and 1958, the highway was rebuilt and reworked into a suitable highway for an eventual extension of US 93. [8] [6] 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. [6] The rest of SR 93 kept its state route designation until 1984. [9]

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.

New bypass bridge

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.

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.
