Miscellaneous notes for Arizona:

There could be some confusion about highways 89 and 89 Alt. because some maps show them as State highways and some maps show them as US highways. North of I-40 they all seem to agree that they are US highways.

Between Flagstaff and Prescott, 89 Alt. is shown as a US highway on some maps and a State highway on other maps. The exit from I-17 south of Flagstaff calls it US 89 Alt.

Between Ash Fork and Wickenburg, some maps show State 89 and some show US 89.

Between Phoenix and Tucson, (through Florence Jct. and Florence) some maps show US 89 and some maps show State 79 (yes, 79 not 89).
