Road Map of Arizona
Explore Arizona's major highways, interstates, and routes. Find detailed information about travel distances, road conditions, and connections across the state.
Which two labeled interstate routes are in the part of Arizona shown in the road map?
Based on the road map of Arizona, the two labeled interstate routes that run through the state are:
- Interstate 10 (I-10) - An east-west highway that enters Arizona from California, passes through Phoenix, and exits into New Mexico.
- Interstate 17 (I-17) - A north-south highway that runs entirely within Arizona, connecting Phoenix to Flagstaff.
These two major interstates form a critical transportation backbone for Arizona, connecting major population centers and providing essential travel corridors through the state.
Arizona Interstates and Major Highways
Arizona's transportation network includes several major interstates and highways that connect cities and regions throughout the state. These routes provide essential travel corridors for both residents and visitors.
Interstate 10
Interstate 10 runs east-west across the southern part of Arizona. It enters the state from California near Ehrenberg, passes through Phoenix and Tucson, and exits into New Mexico near San Simon. It's a major trucking and travel corridor connecting California to the eastern United States.
Interstate 17
Interstate 17 is a north-south highway that runs entirely within Arizona. It connects Phoenix to Flagstaff, climbing from the desert valleys to the high plateaus of northern Arizona. The highway is known for its scenic views and significant elevation changes.
Interstate 8
Interstate 8 is an east-west highway in southern Arizona. It begins at the California border near Yuma and continues east until it connects with Interstate 10 near Casa Grande. The highway traverses the Sonoran Desert and passes through agricultural areas.
Interstate 40
Interstate 40 runs east-west across northern Arizona. It enters from California near Topock, passes through Kingman, Flagstaff, and Winslow, and exits into New Mexico near Lupton. I-40 replaced much of the historic Route 66 and serves as a major cross-country thoroughfare.
Interstate 19
Interstate 19 is a north-south highway that runs entirely within Arizona. It connects Tucson to Nogales at the Mexican border. I-19 is notable as the only highway in the United States that uses metric units (kilometers) on its signs, a remnant from the 1970s metric conversion initiative.
US Route 60
US Route 60 is a major east-west highway that traverses central Arizona. It runs from the California border near Quartzsite through Phoenix and the mining communities of Miami and Globe, and exits into New Mexico near Springerville. Parts of US-60 are now superseded by I-10.
Understanding Arizona's Road System
Arizona's road system is a comprehensive network of interstates, US highways, state routes, and county roads that connect cities, towns, and attractions across the state. The system is designed to accommodate both local traffic and long-distance travelers passing through the state.
The primary interstate highways in Arizona form a pattern that resembles an hourglass, with I-17 serving as the north-south connector between the east-west corridors of I-40 in the north and I-10 in the south. This configuration reflects Arizona's geography and population distribution, with major cities clustered along these main transportation arteries.
When looking at a road map of Arizona, you'll notice that the highway density is greatest in and around Phoenix (Maricopa County) and Tucson (Pima County), with highways radiating outward from these population centers. In more remote areas, highways often follow natural corridors formed by rivers, valleys, and mountain passes.
The state's road system has evolved significantly over time, from early trails and wagon routes to modern multilane highways. Historic routes like US-66 (Route 66) have played important roles in Arizona's development and continue to attract tourists interested in the state's transportation heritage.
