Encyclopedia
State Route 366 is a highway in Graham County, Arizona
that runs from its junction with US 191 south of Safford
to near the summit of Mount Graham
. It is a winding mountain road with one half primarily a northwest-southeast route, the other half being northeast-southwest.
with US 191 at Swift Trail Junction south of Safford. The western terminus of the highway is located near a ranger station near the peak of Mount Graham. The highway heads in a southeastern route as it descends the mountain. There are several hair pin turns as the highway follows the terrain. At Turkey Flat, the highway goes through a series of five hair pin turns. The highway also begins to generally head in a northeasterly direction from this point on. The terrain eventually smooths out and the highway follows a straight path towards the northeast to its eastern terminus at US 191.
SR 366 traverses sparsely inhabited forest and mountain terrain and does not pass through any cities or towns aside from minor settlements. The highway does provide access to Mount Graham, one of the higher peaks in Arizona
at over 10000 feet (3,048 m). It also provides access to the Mount Graham International Observatory

History
SR 366 was established in 1960 from a junction with US 666 (now US 191) to the southwest for 6.3 miles (10.1 km). Later that same year, it was extended an additional 22 miles (35 km) to the Columbine Ranger Station. At this time the road was a gravel road providing access to the Coronado National Forest. Since that time, the easternmost 21.7 miles (34.9 km) have been paved while the rest remains as a gravel road.Junction list
