U.S. Route 180

U.S. Route 180 is an east–west United States highway. Like many three-digit routes, US 180 no longer meets its "parent", US 80. US 80 was decommissioned west of Mesquite, Texas, and was replaced in Texas by Interstate 20 and Interstate 10 resulting in U.S. 180 being longer than U.S. 80. The highway's eastern terminus is in Hudson Oaks, Texas (west of Fort Worth, near Weatherford), at an intersection with Interstate 20. Its western terminus is unclear. Signage at an intersection with State Route 64 in Valle, Arizona 40 miles (64 km) northwest of Flagstaff indicates that the route ends at SR 64, which is consistent with the AASHTO U.S. Highway logs. However, many maps continue the US 180 designation to the south rim of the Grand Canyon at Grand Canyon Village.

Four National Parks can be accessed on the highway, Grand Canyon National Park, Petrified Forest National Park, Guadalupe Mountains National Park, and Carlsbad Caverns National Park. It also passes through the San Francisco Peaks, the highest mountains in Arizona.

U.S. Route 70

U.S. Route 70 (US 70) is an east–west United States highway that runs for 2,385 miles (3,838 km) from eastern North Carolina to east-central Arizona. As can be derived from its number, it is a major east–west highway of the Southern and Southwestern United States. It formerly ran from coast to coast, with the current Eastern terminus near the Atlantic Ocean in North Carolina, and the former Western terminus near the Pacific Ocean in California. Before the completion of the Interstate system, U.S. Highway 70 was sometimes referred to as the "Broadway of America", due to its status as one of the main east–west thoroughfares in the nation.

U.S. 70 begins in Globe at a junction with U.S. Route 60, concurrent with State Route 77. SR 77 splits off east of town. U.S. 70 then enters the San Carlos Apache Indian Reservation and runs southeast for 17 miles (27 km) to Peridot, where it crosses Indian Route 9. It has no other highway junctions until Safford, where it begins a ten-mile (16 km) overlap with U.S. 191. U.S. 70 then runs an additional 37 mi (60 km).
