In the early 1950s, Arizona experimented with color US signs. By the late 1950s the state had switched to the standard black-on-white shields. This assembly was in Tucson. (Photo courtesy of James H. Lindsay).
Arizona has seen quite a few of its US routes decommissioned since the rise of the Interstate systems. At one time Phoenix had four US highways running through it; now there is just one.
Routes that were on Arizona's original 1927 highway plan are marked with a *
|US 60*||US 64||US 70*||US 89*||US 89A||US 93|
|US 95||US 160||US 163||US 180||US 191|
|US 66*||US 80*||US 91*||US 164||US 260*||US 466||US 666|
