U.S. Route 89 (US 89) in the U.S. state of Arizona is a U.S. Highway that begins in Flagstaff and heads north to the Utah border northwest of Page.


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.

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.


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.

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]

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 or US 89X) was the designation for Navajo Route 20 (N20), a road running mostly parallel to US 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 route was 46.17 miles (74.30 kilometres) long. [7]

The need for US 89T arose in February 2013, when a geological event caused a 150-foot (46 m) [8] stretch of US 89 to buckle 25 miles (40 km) south of Page. 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. [9] Motorists were rerouted on a 115-mile (185 km) detour via US 160 and SR 98 or a 90-mile (145 km) 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. [10] [11] In addition to pavement, right-of-way and fencing to separate the road from the local livestock population were required. [12] The improved road opened to traffic on August 29, 2013. Plans called for the road to be used for three years before the road reverted to Bureau of Indian Affairs jurisdiction. [13]

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). [10] As of October 15, US 89T restrictions were lifted following the installation of upgraded control features. [14]

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 Nation in April 2015. The route from The Gap to SR 98 is currently designated only as N20. [15]

Interstate 17 (I-17) is a north–south 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 Numbered 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.

State Route 79, also known as the Pinal Pioneer Parkway, is a 58.40 mi (93.99 km) long state highway in the U.S. state of Arizona. It serves as the main route through the town of Florence, which is also the county seat of Pinal County. Although the highway has been part of the state highway system since at least 1926, it was not designated as SR 79 until 1992. The highway was previously a section of U.S. Route 80 and U.S. Route 89 between Phoenix and Tucson, until both highways were decommissioned in 1977 and 1992 respectively. SR 79 is also the only state highway in Arizona that has a business route, which is SR 79 Business through downtown Florence. SR 79 is also notable for being the location where cowboy western actor Tom Mix lost his life in a car accident on October 14, 1940.

State Route 89A is an 83.85-mile (134.94 km) state highway that runs from Prescott north to Flagstaff in the U.S. state of Arizona. The highway begins at SR 89 and heads northward from Prescott, entering Jerome. From Jerome, the route then heads to Cottonwood and Sedona. The highway is notable for its scenic value as it passes through Sedona and the Oak Creek Canyon. The route then enters Flagstaff, where it crosses Interstate 17 (I-17) and I-40. The highway ends at I-40 Business in Flagstaff. What is now SR 89A became a state highway in the late 1920s as SR 79. The highway was extended and improved several times through 1938. SR 79 was renumbered to U.S. Route 89A in 1941 and then to SR 89A in the early 1990s.

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.

U.S. Route 66 also known as the Will Rogers Highway, was a major United States Numbered Highway in the state of Arizona from November 11, 1926 to June 26, 1985. US 66 covered a total of 385.20 miles (619.92 km) through Arizona. The highway ran from west to east, starting in Needles, California, through Kingman and Seligman to the New Mexico state line. Nationally, US 66 ran from Santa Monica, California, to Chicago, Illinois. In its height of popularity, US 66 was one of the most popular highways in the state of Arizona, sometimes carrying over one million cars a year.

State Route 67 is a 43.4 mi (69.8 km) long, north–south state highway in northern Arizona. Also called the Kaibab Plateau – North Rim Parkway, SR 67 is the sole road that links U.S. Route 89A at Jacob Lake to the North Rim of Grand Canyon National Park. Along the route, the road heads through the national park as well as Kaibab National Forest and is surrounded by evergreen trees. The section inside the national park is maintained by the National Park Service (NPS), whereas the section north of the entrance, completely within Kaibab National Forest, is owned by the Arizona Department of Transportation (ADOT). The road was built in the late 1920s and improved through the 1930s. In 1941, the road received its number, and was given its designation as the parkway in the 1980s. The parkway has received designations as a National Forest Scenic Byway as well as a National Scenic Byway.

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.

From Tempe to Apache Junction, it is known as the Superstition Freeway.

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.

U.S. Route 93 in the state of Arizona is a United States Numbered Highway that begins in Wickenburg and heads north to the Nevada state line at the Mike O'Callaghan–Pat Tillman Memorial Bridge.
