Gila Bend is on I-8.
Gila Bend is 40 miles from Ajo, and it is a town of perhaps a thousand people. Still, there is more action in Ajo, even though it closes down at 9 PM.
It is, which is why it’s effective to navigate around Phoenix on an I-10 trip, since I-10 goes straight through Phoenix, but using I-8 and 85 (which meet at Gila Bend) you can run the other half of the square and skip Phoenix.
