U.S. Route 160 is a 1,465 mile (2,358 km) long east–west United States highway in the Midwestern United States. The western terminus of the route is at US 89 five miles (8 km) west of Tuba City, Arizona. The eastern terminus is at US 67 and Missouri 158 southwest of Poplar Bluff, Missouri.
Its route, if not its number, was made famous in song in 1975, as the road from Wolf Creek Pass to Pagosa Springs, Colorado in C.W. McCall's country music song Wolf Creek Pass.
US 160 begins at US 89 near the western edge of Navajo Nation. Near Tuba City, it intersects State Route 264. It goes through Tonalea and Cow Springs before entering Kayenta, where it intersects U.S. Route 163. It continues northeast through Dennehotso, then has a brief overlap with U.S. Route 191 in Mexican Water. It goes east until Teec Nos Pos, where it intersects U.S. Route 64, then turns northeast to go to the Four Corners and enters New Mexico.
US 160 is one of the major routes crossing the Navajo Nation and in Arizona does not leave the Navajo Nation.
U.S. Route 191 (US-191) is a major north–south state highway through the eastern part of the U.S. state of Utah. The present alignment of US-191, which stretches from Mexico to Canada, was created in 1981 through Utah. Previously the route had entered northern Utah, ending at US-91 in Brigham City, but with the completion of I-15 it was truncated to Yellowstone National Park and re-extended on a completely different alignment. In addition to a large portion of US-163, this extension absorbed several state routes: SR-33, most of SR-44, and SR-260.
US-191 enters Utah on Navajo Nation land and crosses mostly desolate parts of the state. The largest cities served by US-191 are Moab, Price and Vernal. The highway nears the 10,000-foot (3,000 m) level in 2 places in Utah, over Indian Summit near Price and again while crossing the Uintah Mountains near Vernal. It leaves Utah at Flaming Gorge Reservoir. US-191 directly or indirectly serves a number of parks in eastern Utah: Monument Valley Navajo Tribal Park, Glen Canyon National Recreation Area, Hovenweep National Monument, Natural Bridges National Monument, Capitol Reef National Park, Canyonlands National Park, Arches National Park, Dead Horse Point State Park, Dinosaur National Monument, and Flaming Gorge National Recreation Area.
