State Route 77 (or SR 77) is a state highway in Arizona that traverses much of the state's length, stretching from its northern terminus at the boundary of the Navajo Nation north of Holbrook to its junction with I-10 in Tucson.

Route description[edit]

At its southern terminus, north of Tucson, the road is known as Oracle Road[2] until the final mile and a half when the road turns westward directly toward Interstate 10 and is called Miracle Mile Road,[2] named such in 1962.[3]

Route 77 traveling through Salt River Canyon

Past the Navajo Nation boundary, SR 77 becomes BIA Route 6 northbound towards Keams Canyon. Between Show Low and Globe, this highway is concurrent with U.S. Route 60. Its southernmost reaches were formerly part of U.S. Route 80 and U.S. Route 89, except for its terminal segment, the Miracle Mile segment of old Business 10 and State Route 84A.
