The Interstate 17 (abbreviated I-17 ) is an interstate highway , the only north-south direction by the US state of Arizona leads. It begins in Phoenix on Interstate 10 and ends in Flagstaff on Interstate 40 . The southern portion of the highway was built along Arizona State Route 69 , while the northern portion was built along Arizona State Route 79 . The interstate has several exits to lookout points to overlook the mountains and valleys of the northern portion of the highway.
On Interstate 17 are the Montezuma Castle National Monument and the Agua Fria National Monument , as well as the Arcosanti architectural project by the architect Paolo Soleri .
Designations
I-17 is called the Black Canyon Freeway from the north end in Flagstaff to downtown Phoenix . From the curve southwest of downtown between 19th Avenue and Buckeye Road, it is called the Maricopa Freeway . This name is then adopted from I-10 to the eastern outskirts.
Milestones
In Phoenix, Interstate 17 starts, contrary to the usual procedure, with milestone 194 instead of zero. This is a holdover from the old Arizona system that roads that branch off take the mileage from the previous road. Because of this tradition, I-17 got its milestones from Arizona State Route 69, which was replaced by the interstate between Phoenix and Cordes. The milestones of State Route 96 come from the junction with US Highway 89 . When building Interstate 17, the AZ 69 milestones were retained.
