Route description

The eastern terminus of SR 266 is located on US 191 south of Safford. The highway heads southwest from this intersection before curving towards the west.

History

SR 266 was designated in 1957 as a state route from US 666 (now US 191) to Fort Grant. In 1961 the road was a gravel road providing access to the Coronado National Forest and Fort Grant, but it has been completely paved since that time. The highway has had several realignments since the highway was originally designated.
