U.S. Route 160 (US 160) travels west to east across the Navajo Nation and Northeast Arizona for 159.35 miles (256.45 km). US 160 begins at a junction with US 89 north of Cameron and exits the state into New Mexico southeast of the Four Corners National Monument. Along its journey, the route connects the communities of Tuba City, Moenkopi, Rare Metals, Tonalea, Tsegi, Kayenta, Dennehotso, Mexican Water, Red Mesa, and Teec Nos Pos.
The vast majority of US 160's route through Arizona runs through rural and sparsely populated sections. As a result, the road is entirely two-lane except two short four-lane sections in Tuba City and Kayenta. Most of US 160 in Arizona is also known as the Navajo Trail.

The current routing of US 160 was originally designated as Navajo Route 1 (N1) in late 1958, but had yet to be constructed east of Tuba City. Also known as the Navajo Trail, the route was slated to run from U.S. Route 89 (US 89) to the Arizona–New Mexico state line near the Four Corners Monument. The first contract for the construction of N1 past Tuba City was awarded by the Bureau of Indian Affairs (BIA) on July 3, 1959 to the C.R. Davis Contracting Company based in Albuquerque, New Mexico. The contracted stipulated C.R. Davis would construct 9 miles (14 kilometres) of highway northeast of Tuba City at a total cost of $393,202. Another contract to construct a further 10 miles (16 kilometres) of N1 northeast of Tuba City towards Kayenta was awarded in December 1960.[2] On September 9, 1961, the route between US 89 and Teec Nos Pos became a state highway as part of Arizona State Route 64 (SR 64).[3] The reconstructed segment from Teec Nos Pos to the New Mexico state line became SR 364 on September 9, 1961.[4]
On September 12, 1962, a ribbon cutting ceremony was held at Four Corners Monument on September 16, 1962, marking the completion of SR 64 and SR 364 between US 89 and the Arizona–New Mexico border, as well as the continuation of the Navajo Trail into New Mexico and Colorado, before ending at US 666. The ceremony also marked the completion of the Four Corners Monument for motor tourism. Secretary of the Interior Stewart Lee Udall attended the ceremony, as did Governor George Clyde of Utah, Governor Paul Fannin of Arizona, Governor Edwin Mechem of New Mexico, and Governor Stephen McNichols of Colorado were present at the ceremony, joined by Tribal Council members of the Navajo Nation and their families.[5]
On October 1, 1965, most of SR 64 and all of SR 364 became part of the U.S. Highway System, when the American Association of State Highway Officials (AASHO) approved the highway from US 89 to Four Corners as part of U.S. Route 164 (US 164). Nationally, US 164 encompassed the entire length of the Navajo Trail between US 666 in Colorado and US 89 in Arizona, as well as running concurrently with US 89 southwest to a western terminus at US 66 near Flagstaff.[6] June 29, 1970, all of US 164 became a re-routing of US 160 west of Cortez, Colorado. Up to that point, US 160 had not entered Arizona and instead ended at US 6 and US 50 in Crescent Junction, Utah. However, the US 160 designation was only applied to the junction with US 89 north of Flagstaff, with the remainder of US 164 concurrent with US 89 to Flagstaff being removed entirely.[7]
