U.S. 89

U.S. 89

Beginning near Flagstaff and continuing north past the Grand Canyon and Glen Canyon, U.S. 89 provides a scenic route into the national parks of Northern Arizona and Southern Utah. U.S. 89 previously extended south of Flagstaff, continuing to Wickenburg, Phoenix and Tucson before ending at the Mexican Border in Nogales. That portion was eliminated at the American Association of State Highway and Transportation Officials (AASHTO) Route Numbering Committee meeting held June 14, 1992.1

Former U.S. 89 between Flagstaff and Mexico was supplanted by I-40 (Flagstaff to Ash Fork), SR 89 (Ash Fork to Wickenburg), U.S. 93 (Wickenburg), U.S. 60 (Wickenburg to Florence Junction), SR 79 (Florence Junction to Oracle Junction), SR 77 (Oracle Junction to Tucson), Business Loop I-19 (Tucson to Green Valley), and I-19 (Green Valley to Nogales).
