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. [1] 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.

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.

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.

In the U.S. state of Arizona, Interstate 10 (I‑10), the major east–west Interstate Highway in the United States Sun Belt, runs east from California, enters Arizona near the town of Ehrenberg and continues through Phoenix and Tucson and exits at the border with New Mexico near San Simon. The highway also runs through the cities of Casa Grande, Eloy, and Marana. Segments of the highway are referred to as either the Papago Freeway, Inner Loop, or Maricopa Freeway within the Phoenix area, and the Pearl Harbor Memorial Highway outside metro Phoenix.


Route description

Interstate 17 is known as the Black Canyon Freeway from the northern end of the Phoenix Metropolitan Area to a point 2.2 miles (3.5 km) south of The Stack interchange with Interstate 10 northwest of Downtown Phoenix. (It is accompanied by frontage roads for most of this portion, and they carry the Black Canyon Highway name to distinguish from the freeway status.) At the Durango Curve southwest of downtown, between the 19th Avenue and Buckeye Road interchanges, it picks up the designation Maricopa Freeway all the way to the southern terminus at the second Interstate 10 junction. It is one of the metropolitan area's primary freeways. [1] [3] It has two interchanges with Interstate 10 in Phoenix.

The Stack freeway interchange in Phoenix, Arizona

The Stack is a colloquialism used to describe the symmetrical, four-level stack interchange in Downtown Phoenix in the U.S. state of Arizona that facilitates movements between Interstate 17/U.S. Route 60 and Interstate 10.

Downtown Phoenix central business district of Phoenix, Arizona

Downtown Phoenix is the central business district (CBD) of the City of Phoenix, Arizona, United States. It is located in the heart of the Phoenix metropolitan area or Valley of the Sun. Phoenix, being the county seat of Maricopa County and the capital of Arizona, serves as the center of politics, justice and government on the local, state and federal levels. The area is a major center of employment for the region, with many financial, legal, and other national and international corporations housed in a variety of skyscrapers. Major arts and cultural institutions also call the area home. Downtown Phoenix is a center of major league sports activities, live concert events, and is an equally prominent center of banking and finance in Arizona. Regional headquarters for several major banks, including JP Morgan Chase, Wells Fargo, US Bank, Bank of America, Compass Bank and Midfirst Bank are all located within or close proximity to the area.

Frontage road Type of road

A frontage road is a local road running parallel to a higher-speed, limited-access road. A frontage road is often used to provide access to private driveways, shops, houses, industries or farms. Where parallel high-speed roads are provided as part of a major highway, these are also known as local-express lanes.

I-17 has the unusual distinction of starting at approximately milepost 194 instead of at milepost zero. This is a holdover from Arizona's old system of marking mileposts, where a branching route would continue the milepost numbering of its original host, instead of starting over at zero. Interstate 17 inherited its milepost locations from SR 69, which the freeway replaced between Phoenix and Cordes Junction. SR 69's mileposting was such that it coincided with US 89's mileposting, which was 201.6 where the two routes intersected. When I-17 was constructed, the existing mileposting for SR 69 was retained. [1] [3]

State Route 69 is a highway that serves as the main road to Prescott, Arizona, from Interstate 17. It is almost all divided four-lane although some sections in Prescott and Prescott Valley are wider). Prior to the construction of Interstate 17, State Route 69 continued south to Phoenix, Arizona, as the Prescott-Phoenix Hwy or Black Canyon Highway on a different alignment, through the ghost towns of Bumble Bee and Cordes.

I-17 is closed to bicycles and pedestrians south of Pioneer Road (exit 225) in the Anthem area, but is open to them north of this point.

Munds Park, Arizona CDP in Arizona, United States

Munds Park is a rural, unincorporated census-designated place (CDP) in Coconino County, Arizona, United States, in the region known as Northern Arizona. The year round population was 631 at the 2010 census.

Flagstaff, Arizona City in Arizona, United States

Flagstaff is a city in and the county seat of Coconino County in northern Arizona, in the southwestern United States. In 2015, the city's estimated population was 70,320. Flagstaff's combined metropolitan area has an estimated population of 139,097. The city is named after a ponderosa pine flagpole made by a scouting party from Boston to celebrate the United States Centennial on July 4, 1876.

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.


In 1936, SR 69 was established as a state route from Phoenix north to Prescott. [4] [5] The road was completed by 1940 to Prescott. In 1954, a new route north to Flagstaff was established as SR 79. By 1961, the roadway from Phoenix to Flagstaff had been established, but not to Interstate standards. [6] By 1971, I-17 had been completed from Phoenix northward to Camp Verde where a short stretch had not been completed to standards. The stretch from SR 279 north to SR 179 was also complete. The largest section yet to be completed was from SR 179 north to Flagstaff. This segment was still just a two-lane roadway, but it did have full traffic interchanges built at crossroads. The portion from I-40 south to the Flagstaff Municipal Airport had been completed by this time. [7]

Prescott, Arizona City in Arizona, United States

Prescott is a city in Yavapai County, Arizona, United States. According to the 2010 Census, the population of the city is 39,843. The city is the county seat of Yavapai County. In 1864 Prescott was designated as the capital of the Arizona Territory, replacing the temporary capital at Fort Whipple. The Territorial Capital was moved to Tucson in 1867. Prescott again became the Territorial Capital in 1877, until Phoenix became the capital in 1889.

State Route 179, also known as SR 179, the Red Rock Scenic Byway, a north–south state highway in Arizona, United States, running from Interstate 17 to SR 89A in Sedona, entering Coconino County from Yavapai County. In 2006, the US Dept. of Transportation awarded SR 179 its highest designation within the National Scenic Byways Program: the All-American Road designation, due to the red rock and sandstone formations through which it travels along its 7.5-mile (12.1 km) length within the hills of the Coconino National Forest. The All-American Road designation also signifies to the travelling public that this is a road that is "a destination unto itself".

State Route 85 is a 128.86-mile-long (207.38 km) state highway in the U.S. state of Arizona. The highway runs from the United States-Mexico border near Lukeville to the north ending at Interstate 10 (I-10) in Buckeye. The highway also intersects I-8 in Gila Bend and serves as a connector between I-8 and I-10 and for travelers between Phoenix and Yuma as well as San Diego. SR 85 between I-10 and I-8, as well as I-8 between SR 85 and I-10 in Casa Grande, is touted as a bypass of the Phoenix area for long-distance travelers on I-10.

Arizona State Route 51 freeway in the Phoenix metropolitan area

Arizona State Route 51 (SR 51), also known as the Piestewa Freeway, is a numbered state highway in Phoenix, Arizona. It connects Interstate 10 just outside Downtown Phoenix with Loop 101 on the north side of Phoenix, making it one of the area's major freeways. It is a largely north–south route and is known for traversing the Piestewa Peak Recreation Area. The peak was named after Lori Piestewa, the first Native American woman to die in combat in the U.S. Military. Prior to this time, the freeway was known as the Squaw Peak Parkway, a name considered offensive by many Native Americans. Rapid growth and increased traffic demand on the east side of Metro Phoenix made the Piestewa Freeway necessary.

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.

Arizona State Route 101 freeway in the Phoenix metropolitan area

Arizona State Route 101, or Loop 101, is a semi-beltway encompassing much of the Phoenix Metropolitan Area in the United States. It connects several suburbs of Phoenix, including Tolleson, Glendale, Peoria, Scottsdale, Mesa, Tempe, and Chandler. Construction began in the late-1980s and was completed in 2001. Additional general purpose lanes and a high occupancy vehicle lane (HOV) are being constructed along the eastern stretch of Loop 101 from Scottsdale to Chandler, starting at Princess Drive to Loop 202.

State Route 202 or Loop 202 is a partial beltway looping around the eastern areas of the Phoenix metropolitan area in central Arizona. It traverses the eastern end of the city of Phoenix, in addition to the towns of Tempe, Mesa, Chandler, and Gilbert, and is a vital route in the metropolitan area freeway system. Loop 202 has two currently officially designated sections along its route; the Red Mountain Freeway and the Santan Freeway. The Red Mountain Freeway runs from the Mini Stack Interchange in Phoenix with Interstate 10 (I-10) and State Route 51 (SR 51) in Phoenix to the SuperRedTan Interchange with U.S. Route 60 in Mesa, and the Santan Freeway runs from there to an interchange with Interstate 10 (I-10) in Chandler. A third section currently under construction, the South Mountain Freeway, will run from there to Interstate (I-10) in western Phoenix.

Arizona State Route 143, also known as SR 143 and the Hohokam Expressway, is a north–south and access-controlled freeway in Maricopa County, Arizona, that runs from a junction with Interstate 10 at 48th Street in Phoenix to McDowell Road. The only other major junction along the 3.93-mile (6.32 km) route is with Loop 202, which is located one half-mile south of McDowell Road and the northern terminus.

State Route 153, also known as SR 153 and the Sky Harbor Expressway, is a former state highway in Maricopa County, in the U.S. state of Arizona, that ran from the intersection of 44th Street and Washington Street in Phoenix south to University Drive. It was a controlled access arterial expressway, with a speed limit of 45 mph (72 km/h), lower than the standard freeway speed of 65 mph (105 km/h). Route 153 was a north–south route that skirted the eastern edge of Sky Harbor International Airport, and along with SR 143, SR 153 served a portion of East Valley residents with access to the airport. Many motorists used SR 143 instead, because of its quick access to and from Interstate 10 and Loop 202. The freeway did, however, provide a direct link to office developments in the Southbank commercial project in east Phoenix with the city of Tempe.

State Route 84, also known as SR 84, is a 23-mile (37 km) east–west highway in south-central Arizona, with its western terminus at Exit 151 of Interstate 8 and its eastern terminus at its junction with State Route 387 and State Route 287 in Casa Grande. An orphaned and unsigned section runs along the final 0.87 miles (1.40 km) of State Route 87 just north of Interstate 10 near Picacho. Formerly, SR 84 ran between Tucson and Gila Bend, serving as the primary route for travelers to San Diego, California and bypassing U.S. Route 80 through Phoenix. SR 84 was also part of the Broadway of America transcontinental highway in the mid-20th Century. It was mostly replaced by both I-10 and I-8 in the late 1960s and early 1970s.

Arizona State Route 303 highway in Arizona

Arizona State Route 303, also known as Loop 303 or Bob Stump Memorial Parkway and formerly called Estrella Freeway, is a freeway that serves the northwestern portion of the Phoenix area. The freeway, originally a two-lane rural highway, was maintained by Maricopa County in central Arizona serving the far western suburbs of the Phoenix metropolitan area until 2004 when the Arizona Department of Transportation again took the control of upgrading the interim road to a freeway. In 2004, it was renamed "Bob Stump Memorial Parkway" to honor former Arizona congressman Bob Stump.

State Route 83 is a scenic state highway in southern Arizona, stretching from its junction with Interstate 10 near Vail south to Parker Canyon Lake. It passes through sparsely populated areas of Pima, Cochise and Santa Cruz Counties, passing through the wine towns of Sonoita and Elgin.

Arizona State Route 587 highway in Arizona

State Route 587, also known as SR 587, is a state highway in south-central Arizona that travels from its junction with State Route 87 just south of Sun Lakes directly south to Interstate 10 in Bapchule. The entire highway is just six miles (10 km) long, traveling entirely within the Gila River Indian Reservation, and serves as a shortcut from the far southern suburbs of the Phoenix metropolitan area to Interstate 10.

Arizona State Route 347 highway in Arizona

State Route 347, also known as John Wayne Parkway, is a 28.69 miles (46.17 km) long, north–south state highway in central Arizona. The route begins at SR 84 and heads north. It passes through Maricopa, meeting SR 238. The route ends at an interchange with Interstate 10 (I-10) south of Chandler. It primarily serves as the major road to Maricopa; much of the road lies within the Gila River Indian Community, with another short stretch through the Ak-Chin Indian Community. The road was built in the late 1930s and established as a state highway in the 1990s. On average, between 4,000 and 35,000 vehicles use the roadway daily.

State Route 24, formerly State Route 802, also known as Gateway Freeway and Williams Gateway Freeway, is a freeway in the extreme southeastern region of the Phoenix Metropolitan Area. The roadway is planned as a controlled-access highway to move traffic from the southeastern suburbs of Phoenix to planned ones in northwestern Pinal County. It is the lowest-numbered state route in Arizona. The first mile from Loop 202 to Ellsworth Road opened on May 4, 2014. Planning for future sections has been halted until studies for the Pinal North-South Freeway are completed to confirm how the two freeways will intersect.

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.

The transportation system of Arizona comprises rail, air, bus, car and bicycle transport.

The Pinal North–South Freeway is a planned freeway in the extreme southeastern region of the Phoenix Metropolitan Area currently under study by the Arizona Department of Transportation (ADOT). If constructed, the roadway would serve as a Phoenix–Mesa bypass for cities and suburbs in far eastern Maricopa County and northwestern Pinal County.
