The Catalina Highway begins at its intersection with Tanque Verde Road in northeast Tucson, traversing the unincorporated community of Tanque Verde before crossing into the Coronado National Forest.At this point, the roadway officially becomes the General Hitchcock Highway (Arizona Forest Highway 39), although many maps reflect the common usage of "Catalina Highway" to refer to the entire roadway. Please drive slowly and turn on headlights for safety.
