Phoenix to Tucson by road
The fastest driving route is 116 miles (187 km) long and takes about 2 hr 10 min without stops or traffic. It runs mostly on I-10 (96.0 mi) and I-17 (14.0 mi).
The whole route stays in Arizona. That’s an average of 54 mph (87 km/h). AAA recommends a break every two hours or 100 miles: with 1 stop of 20 minutes, the trip takes about 2 hr 30 min. The time is OSRM’s estimate with OpenStreetMap data: no traffic and speeds somewhat below the limits, so real trips can differ.
Straight-line distance and bearing
In a straight line, the shortest distance over the Earth’s surface, Phoenix and Tucson are 108 miles (173 km) apart. That’s the geodesic on the WGS84 ellipsoid, the distance “as the crow flies”.
The road is 8% longer: for every 100 miles in a straight line you drive 108. The route runs almost straight. Of the 110 US driving pairs in this series, it ranks 100th for detour (the average is 16%).
From Phoenix, Tucson lies to the southeast (bearing 141°), and from Tucson, Phoenix lies to the northwest.
