 This provides a shortcut for traveling between Bowie and Safford, as the mainline of US 191 is curved toward the west near I-10.Going toward Safford, the eastern terminus of two state routes intersect the route, namely SR 266, which provides access to Fort Grant, and SR 366 in Swift Trail Junction, which climbs up to the summit of Mount Graham and provides access to Mount Graham International Observatory.Arriving in Safford, US 191 turns east at an intersection with 5th Street (US 70), where its concurrency with US 70 begins.
