US 191 turns northeast to split from US 70. The route heads toward Three Way, passing through the Black Hills and entering Greenlee County. At Three Way, US 191 turns to the north, but the intersection is the northern terminus of SR 75, which heads toward Duncan, and the western terminus of SR 78, which heads into New Mexico toward Mule Creek. Heading north, US 191 is a divided highway for about until it arrives in Clifton, the start of the road's designation as the Coronado Trail Scenic Road (both an Arizona Scenic Route and a National Scenic Byway). This scenic road approximates the route taken by Francisco Vázquez de Coronado between 1540 and 1542. At the intersection with Zorrilla Street in Clifton, the US 191 designation temporarily ends and the road continues as US 191 Temporary through the Morenci mine . At the northern end of the Morenci mine, the road reacquires its US 191 designation and travels through the Apache–Sitgreaves National Forests, in which it enters Apache County. The road through the forests is dangerous with no shoulders and many hairpin turns along steep mountainsides. About through the forests, US 191 arrives in Alpine and intersects US 180, where their concurrency begins. Continuing through the forests, the road travels through the community of Nutrioso before leaving the Apache–Sitgreaves National Forests. Just after leaving the forests, US 180/US 191 turns north at a T-intersection, the eastern terminus of SR 260. About to the northwest, US 180/US 191 enters Springerville and turns to the west at another T-intersection, this time with Main Street, where a triple concurrency between US 60, US 180, and US 191 begins. This triple concurrency passes through Springerville and ends about northwest of Springerville, where US 180/US 191 turns north and the road continues west as US 60. The US 180/US 191 concurrency continues north for another , intersecting former SR 81, which leads to Lyman Lake State Park before arriving in St. Johns as White Mountain Drive. St. Johns to Utah In St. Johns, US 180/US 191 intersects Commercial Street (SR 61), where the US 180/US 191 concurrency ends but a concurrency with SR 61 begins. This concurrency leaves St. Johns and travels north for about until SR 61 turns to the northeast and heads toward Zuni, New Mexico. Continuing north, US 191 immediately enters the Navajo Nation and then travels another until it arrives
