Phoenix to Puerto Peñasco by road
The fastest driving route is 213 miles (343 km) long and takes about 4 hr 50 min without stops or traffic. It runs mostly on AZ 85 (114 mi), the MEX 8 (62.0 mi), and I-10 (30.8 mi).
Of the 213 mi, 150 mi are in the United States and 63.2 mi are in Mexico. That’s an average of 44 mph (71 km/h). AAA recommends a break every two hours or 100 miles: with 2 stops of 20 minutes, the trip takes about 5 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 Puerto Peñasco are 170 miles (274 km) apart. That’s the geodesic on the WGS84 ellipsoid, the distance “as the crow flies”.
The road is 25% longer: for every 100 miles in a straight line you drive 125. That’s a normal detour between two cities. Of the 16 US–Canada and US–Mexico driving pairs in this series, it ranks 3rd for detour (the average is 22%).
From Phoenix, Puerto Peñasco lies to the southwest (bearing 211°), and from Puerto Peñasco, Phoenix lies to the northeast.
Halfway between Phoenix and Puerto Peñasco
Halfway along the straight line, 85.0 miles (137 km) from each city, is the point 32.3850° N, 112.8146° W. It falls near Why (Arizona, pop. 52), 10.0 mi away. The nearest town of 20,000 people or more is Puerto Peñasco (Sonora, Mexico, pop. 62,689), 85.0 mi away.
By road, the halfway point is 107 miles (172 km) from each city, near Why (Arizona, pop. 52), 14.5 mi away. The nearest town of 20,000 people or more is Puerto Peñasco (Sonora, Mexico, pop. 62,689), 86.3 mi away. The two midpoints almost coincide (4.7 mi apart), because the road doesn’t stray far from the straight line.
