29: I-17 in Arizona
Back into the desert of Arizona, we take a look at I-17, the stretch between Flagstaff and Phoenix. The interstate is known for being increasingly long to drive, with plenty of open space but little to no tourist attractions. If you like to stop along the way at gas stations or restaurants you won’t find much on this stretch. The area has also been affected by wildfires in the past decade, which have negatively affected the natural beauty of the area.

Nevertheless, if you love cruising along a desert road with plenty of open space, I-17 is the ultimate day trip. You’ll want to take someone along for the ride because this is perhaps one of the most daunting roads in the country.
