US 180 skirts the San Francisco Peaks on its way to the Grand Canyon.
Although the ADOT map and highway log indicates this highway goes to the Grand Canyon National Park boundary, there is an END sign where it meets AZ 64.
The multiplex with I-40 isn't well marked. Although there are reassurance markers along with most of the I-40 signs, there are no references to US 180 on intersecting roads, nor are there signs directing you eastbound through Flagstaff. If you're going east, US 180 seems to vanish at Business I-40.
US 180 serves the south entrance to the Petrified Forest National Park. If you're traveling I-40, you can use US 180 to go through the park without backtracking.
US 180 was replaced by US 70 in 1936. The number was reestablished when it replaced US 260 on it's route from Alpine to Holbrook in 1961. In 1963 it was extended along US 66/I-40 to Flagstaff, then replaced AZ 164 to Valle. It then joined with AZ 64 the rest of the way to the Grand Canyon.
