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. ==Route description== 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. |- |AZ |292 |470 |- |NM (Southwest) |248 |399 |- |TX (Trans-Pecos) |146 |235 |- |NM (Southeast) |110 |180 |- |TX (Northwest) |339 |546 |- |Total |1135 |1827 |} 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「U.S. Route 180」の詳細全文を読む スポンサード リンク
