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. [2] 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.

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. [2] [3] It has two interchanges with Interstate 10 in Phoenix.

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. [2] [3]

I-17 is closed to bicycles and pedestrians south of Anthem Way (exit 229) in the Anthem area, but is open to them north of this point.


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]


The existing interchange with Happy Valley Road in Phoenix is currently being converted to a diverging diamond interchange (DDI). The project is projected to be finished in the fall of 2020. [8]

Former business route

Black canyon city

State Business Route 17
Location Black Canyon City
Length3.0 mi (4.8 km)

State Business Route 17 (also known as SR 17 Bus.) was a former 3.0-mile (4.8 km) business loop of Interstate 17 that served the west side of Black Canyon City, Arizona. I-17 Business followed Old Black Canyon Highway (formerly SR 69 before I-17 replaced most of the route between Phoenix and Cordes Junction) from Exit 244 north of town at a diamond interchange to another diamond interchange at Exit 242. The business route was subsequently transferred from state to local maintenance and because of ADOT's policy of not signing business loops on non-state maintained roadways, the route was decommissioned in 2011. [9]

Major intersections
The entire route is in Yavapai County.
