Unpaved section of roadway to remain closed until spring
SAFFORD – The upper, unpaved section of State Route 366, which ascends Mount Graham in the Pinaleno Mountains southwest of Safford, has closed for the winter, according to the Arizona Department of Transportation.
The closure is in effect through April 15.
SR 366, also known as the Swift Trail, begins about 5 miles south of Safford off of US 191.
The highway is closed about one-half mile past the Coronado National Forest’s Shannon Campground, at the end of the pavement.
Motorized vehicles aren’t allowed on SR 366 past the locked gate. Hikers, mountain bikers and cross-country skiers can still use the area.
ADOT will close lower portions of SR 366 as needed to clear snow.
