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.

Route description

U.S. 89 begins at Flagstaff, Arizona. The highway proceeds north passing near Grand Canyon National Park and through the Navajo Nation. Near the Utah state line the highway splits into U.S. 89 and U.S. Route 89A. The Alternate is the original highway; what is now the main highway was constructed in the 1960s to serve the Glen Canyon Dam. The two highways rejoin in Kanab, Utah.

Grand Canyon National Park national park of the United States in Arizona

Grand Canyon National Park, located in northwestern Arizona, is the 15th site in the United States to have been named a national park. The park's central feature is the Grand Canyon, a gorge of the Colorado River, which is often considered one of the Wonders of the World. The park, which covers 1,217,262 acres of unincorporated area in Coconino and Mohave counties, received more than six million recreational visitors in 2017, which is the second highest count of all American national parks after Great Smoky Mountains National Park. The Grand Canyon was designated a World Heritage Site by UNESCO in 1979.

Navajo Nation US Indian reservation

The Navajo Nation is a Native American territory covering about 17,544,500 acres, occupying portions of northeastern Arizona, southeastern Utah, and northwestern New Mexico in the United States. This is the largest land area retained by a Native American tribe, with a population of roughly 350,000 as of 2016.

U.S. Route 89A highway in Arizona and Utah

U.S. Route 89A is a north–south auxiliary U.S. highway, though its actual direction of travel is more east–west. The highway is an old routing of U.S. Route 89 from Bitter Springs, Arizona to Kanab, Utah. The state of Arizona has designated this highway the Fredonia-Vermilion Cliffs Scenic Road. The highway is used to access Grand Canyon National Park and is known for the Navajo Bridge. Until 2008, the Utah portion was signed State Route 11.

The main branch passes over the Colorado River just south of the Glen Canyon Dam and Lake Powell near Page then enters Utah. The Alternate branch crosses the Colorado River at Navajo Bridge and proceeds to the North Rim of the Grand Canyon before entering Utah.

Colorado River major river in the western United States and Mexico

The Colorado River is one of the principal rivers in the Southwestern United States and northern Mexico. The 1,450-mile-long (2,330 km) river drains an expansive, arid watershed that encompasses parts of seven U.S. and two Mexican states. Starting in the central Rocky Mountains of Colorado, the river flows generally southwest across the Colorado Plateau and through the Grand Canyon before reaching Lake Mead on the Arizona–Nevada border, where it turns south toward the international border. After entering Mexico, the Colorado approaches the mostly dry Colorado River Delta at the tip of the Gulf of California between Baja California and Sonora.

Lake Powell reservoir in the United States

Lake Powell is a reservoir on the Colorado River, straddling the border between Utah and Arizona, United States. Most of Lake Powell, along with Rainbow Bridge National Monument, is located in Utah. It is a major vacation spot that around two million people visit every year. It is the second largest man-made reservoir by maximum water capacity in the United States behind Lake Mead, storing 24,322,000 acre feet (3.0001×1010 m3) of water when full. However, due to high water withdrawals for human and agricultural consumption, and because of subsequent droughts in the area, Lake Mead has fallen below Lake Powell in size several times during the 21st century in terms of volume of water, depth and surface area.

Page, Arizona City in Arizona, United States

Page is a city in Coconino County, Arizona, United States, near the Glen Canyon Dam and Lake Powell. As of the 2010 census, the population of the city was 7,247.

History

Directional colored shields found on US 89 during the 1950s.

Prior to 1992, [2] the southern terminus of US 89 was at Nogales, Arizona. US 89 ran concurrently with Interstate 19 (I-19) until Green Valley. The route was taken (in a northerly direction) through Tucson via 6th Avenue, Congress Street and Granada Avenue. The route was carried out of Tucson via State Route 77 (SR 77). Further north it was carried via the Pinal Pioneer Parkway northwest out of Oracle Junction on SR 79. In Maricopa County, it ran concurrently with existing US 60 along Main Street in Mesa, Apache Boulevard and Mill Avenue in Tempe, then along Van Buren Street in Phoenix to Grand Avenue, [3] then to Wickenburg. Departing Wickenburg, it followed US 93 and SR 89 to Prescott. Departing Prescott, the route followed present-day SR 89 to Ash Fork, then ran east concurrently with I-40 to Flagstaff.

Nogales, Arizona City in Arizona, United States

Nogales is a city in Santa Cruz County, Arizona. The population was 20,837 at the 2010 census and estimated 20,407 in 2014. Nogales forms part of the larger Tucson-Nogales combined statistical area, with a total population of 1,027,683 as of the 2010 Census. The city is the county seat of Santa Cruz County.

Green Valley, Arizona CDP in Arizona, United States

Green Valley is a census-designated place (CDP) in Pima County, Arizona, United States. The population was 23,765 at the 2010 census.

State Route 77 is a state highway in Arizona that traverses much of the state's length, stretching from its northern terminus at the boundary of the Navajo Nation north of Holbrook to its junction with I-10 in Tucson.

In Flagstaff, US 89 ran along old Route 66, Milton Road and Santa Fe Avenue. The highway crossed the Little Colorado River at Cameron on the Cameron Suspension Bridge until 1959, when the bridge was retired and replaced by a parallel span. [4]

U.S. Route 66 in Arizona former highway in Arizona

U.S. Route 66 covered 401 miles (645 km) as part of a former United States Numbered Highway in the state of Arizona. The highway ran from west to east, starting in Needles, California, through Kingman and Seligman to the New Mexico state line as part of the historic US 66 from Santa Monica, California, to Chicago, Illinois. The highway was decommissioned in 1985, although portions remain as State Route 66 (SR 66).

Little Colorado River river in the United States of America

The Little Colorado River is a tributary of the Colorado River in the U.S. state of Arizona, providing the principal drainage from the Painted Desert region. Together with its major tributary, the Puerco River, it drains an area of about 26,500 square miles (69,000 km2) in eastern Arizona and western New Mexico. Although it stretches almost 340 miles (550 km), only the headwaters and the lowermost reaches flow year-round. Between St. Johns and Cameron, most of the river is a wide, braided wash, only containing water after heavy snowmelt or flash flooding.

Cameron, Arizona CDP in Arizona, United States

Cameron is a census-designated place (CDP) in Coconino County, Arizona, United States. The population was 885 at the 2010 census. Most of the town's economy is tourist food and craft stalls, restaurants, and other services for north-south traffic from Flagstaff and Page. There is a ranger station supplying information and hiking permits for the Navajo Nation as well as a small selection of books for sale. There is also a large craft store run by the Nation itself; most vendors in the area operate from small private stalls.

On February 20, 2013, [5] the main alignment of US 89 was closed in both directions approximately 25 miles (40 km) south of Page due to a landslide that caused the roadway to buckle and subside. Traffic was re-routed via 45 miles (72 km) of secondary and tertiary roads on the Navajo Reservation. Alternate routes through Las Vegas, Nevada, or Hurricane, Utah, and Marble Canyon (US 89A) were also suggested. [6] US 89T (see below) opened in August 2013 as a bypass of the closed section, utilizing Navajo Route 20 as an alignment.

U.S. 89 reopened in March 2015 after a $25 million repair project. [5]

U.S. Route 89T (US 89T) was the designation for Navajo Route 20 (N20), a 44-mile (71 km) road running mostly parallel to U.S. 89 in Arizona. Added to the Arizona state highway system in 2013, US 89T served as a temporary detour for a closed section of US 89.

The need for US 89T arose in February 2013, when a geological event caused a 150-foot (46 m) [7] stretch of US 89 25 miles (40 km) south of Page to buckle. The loss of this stretch of road forced detours for traffic entering the Page area from the south. The Navajo Nation declared a state of emergency. [8] Motorists were rerouted on a 115-mile (185 km) detour via US 160 and SR 98 or a 90-mile detour on N20, which had a 28-mile (45 km) unpaved stretch. At the same time, commute times into Page increased, and merchants in Page and the surrounding area lost significant business.

The Arizona Department of Transportation (ADOT) added the road to the state highway system as US 89T and quickly moved to get money ($35 million from the Federal Highway Administration's emergency relief project fund) and equipment to pave the road. As the Navajo had wanted to pave N20 for decades, and some design and environmental clearances had already been obtained, it took just 79 days to pave N20 in a project that might have otherwise taken more than a year. [9] [10] In addition to pavement, right-of-way and fencing to separate the road from the local livestock population were required. [11] The improved road opened to traffic on August 29, 2013. Plans call for the road to be used for three years before the road reverts to Bureau of Indian Affairs jurisdiction. [12]

Initially, the route lacked proper fencing, cattle guards, and pavement markings to support safe travel at higher speeds. As a result, US-89T was open to local traffic only at night, and posted speed limits as low as 25 miles per hour (40 km/h). [9] As of October 15, US-89T restrictions were lifted following the installation of upgraded control features. [13]

With the reopening of mainline US 89 in March 2015, the US 89T designation was retired and ownership of the route returned to the Navajo Reservation in April 2015. [14]

Interstate 17 (I-17) is an Interstate Highway located entirely within the U.S. state of Arizona. I-17's southern terminus lies within Phoenix, at Interstate 10, and its northern terminus is in Flagstaff, at Interstate 40. The majority of I-17 is known as the Arizona Veterans Highway. In the Phoenix metropolitan area, it is mostly known as the Black Canyon Freeway, however the southern 4.16 miles (6.69 km) is part of the Maricopa Freeway. The portion of the highway south of Cordes Lakes was built along the alignment of SR 69, while the northern part was built along old SR 79's alignment. I-17 is one of the most scenic Interstate Highways as it gains more than a mile in altitude between Phoenix at 1,117 feet (340 m) and Flagstaff at 7,000 feet (2,100 m). The highway features several scenic view exits along its route that overlook the many mountains and valleys found in northern Arizona.

U.S. Route 180 highway in the United States

U.S. Route 180 is an east–west United States highway. Like many three-digit routes, US 180 no longer meets its "parent", US 80. US 80 was decommissioned west of Mesquite, Texas, and was replaced in Texas by Interstate 20 and Interstate 10 resulting in U.S. 180 being longer than U.S. 80. The highway's eastern terminus is in Hudson Oaks, Texas, at an intersection with Interstate 20. Its western terminus is unclear. Signage at an intersection with State Route 64 in Valle, Arizona 40 miles (64 km) northwest of Flagstaff indicates that the route ends at SR 64, which is consistent with the AASHTO U.S. Highway logs. However, many maps continue the US 180 designation to the south rim of the Grand Canyon at Grand Canyon Village. Signage at the SR 64 intersection as late as 2011 indicated that US 180 continues north concurrent with the route. However, no signage along the route exists past this intersection until SR 64 turns east towards Cameron, Arizona. At this intersection, signage makes no mention of US 180 nor is there any mention at the terminus of SR 64 at US 89.

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.
