Interstate 17
Interstate Highway in Maricopa, Yavapai, and Coconino counties in Arizona, United States
Interstate 17 (I-17) is a north–south Interstate Highway located entirely within the US state of Arizona. I-17's southern terminus lies in Phoenix, at I-10/US 60 and its northern terminus is in Flagstaff, at I-40.
Most 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) are part of the Maricopa Freeway. The portion of the highway south of Cordes Lakes was built along the alignment of State Route 69 (SR 69), while the northern part was built along old SR 79's alignment. The final section of I-17 was completed in 1978.
I-17 gains more than one mile (1.6 km) in elevation 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 in northern Arizona.
Route description
I-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 I-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 I-10 junction.
