Ajo Arizona Business District Bypass
(Traffic Loop)

The route from Phoenix to Rocky Point (Puerto Penasco) Mexico passes through Ajo, Arizona. Ajo is your last chance, before crossing the border, for decent restaurants, groceries and lodging, as well as multiple choices for gasoline and Mexico travel insurance. If you have no need for these products and services, you can loop around the Ajo business district. This is an opportunity to save a few minutes only on days of heavy traffic, since the loop is longer than the business route.

Ajo Traffic Loop

Ajo Business District Bypass
Southbound

From southbound Route 85, at milepost 35+, take a left on Mead Road. Mead takes a sharp left at the entrance to the Ajo Country Club and Airport, so be careful and reduce your speed from the posted speed limit of 45 MPH. Mead merges into Ajo Well Road and eventually intersects Route 85. Turn left on Rt 85. The Mexico border is about 45 miles south.

 

Ajo Business District Bypass (Traffic Loop)
Northbound

From northbound Rt 85 turn right at Ajo Well Road. Continue north for 5.8 miles, then merge left onto Mead Road. Continue on Mead to the end. Turn right on Rt 85 to go to Gila Bend and Phoenix.

Speed Limits, Travel Times and Mileage

The bypass is 8.2 miles and, at the posted speed limits, takes 12 minutes. The business route is 7.2 miles and, at the posted speed limits, takes 10 minutes. On days of heavy traffic to, and from, Rocky Point, it is not likely that traffic through the business district will flow at the posted speed limit. The traffic loop, however, has no businesses, or cross traffic, to hinder traffic.

Whether you drive through the business district, or take the bypass, be informed that speed limits are enforced aggressively.

Here are the posted speed limits for both routes through Ajo (North to South):
