'''Interstate&nbsp;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, Arizona|Phoenix]], at [[Interstate 10 in Arizona|I-10]]/[[U.S. Route 60 in Arizona|US 60]] and its northern terminus is in [[Flagstaff, Arizona|Flagstaff]], at Milton Road north of [[Interstate 40 in Arizona|I-40]].<ref name="ADOT NHS Map"/>

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 {{convert|4.16|mi|km}} are part of the '''[[Maricopa Freeway]]'''. The portion of the highway south of [[Cordes Lakes, Arizona|Cordes Lakes]] was built along the alignment of [[Arizona State Route 69|State Route&nbsp;69]] (SR&nbsp;69), while the northern part was built along old [[Arizona State Route 89A#History|SR&nbsp;79]]'s alignment. The final section of I-17 was completed in 1978.

I-17 gains more than {{Convert|1|mi|km|spell=in}} in elevation between Phoenix at {{convert|1,117|ft|m}} and Flagstaff at {{convert|7,000|ft|m}}. The highway features several scenic view exits along its route that overlook the many mountains and valleys in northern Arizona.
