US 180 in Arizona
|Get started||Grand Canyon|
According to Directoryaah, US 180 is a US Highway in the US state of Arizona. The road forms an east-west route through the center and east of the state. The exact beginning is unclear, the road begins in Grand Canyon at the Grand Canyon, or at an intersection with SR-64 in uninhabited land 80 kilometers northwest of Flagstaff. The road runs to the New Mexico border, and is significantly double – numbered with Interstate 40 and US 191. The road is 467 or 422 kilometers long.
The road begins in Grand Canyon National Park on the south side of the Grand Canyon in the village of the same name. The road then heads south, and after 45 kilometers reaches its second possible starting point, an intersection with SR-64 in the desert, in Valle, a hamlet with only an airport and a gas station. The road then heads east at an elevation of 1,900 meters and begins a climb through the San Francisco Mountains.
US 180 east of Holbrook.
The road runs through the forests of the Kaibab National Forest and rises to an altitude of 2,400 meters, right past the 3,850-meter Humphreys Peak, the highest mountain in Arizona. One then reaches the town of Flagstaff, which consists mainly of business parks and commercial strips as it is the main town within 200 kilometers. The road merges here with Interstate 40 and then begins a 145-kilometer double numbering. Interstate 17 from Phoenix also ends here. The road then heads east on I-40, through the endless deserts through virtually uninhabited land. Only the town of Winslow is on the route, but no other roads are crossed here.
At Holbrook, US 180 exits from I-40, then heads southeast. I-40 continues east toward Albuquerque. The road then runs past the Petrified Forest National Park, which is home to petrified trees. At St. Johns, the road merges with US 191 from Moab in Utah. Both roads then run to the south and are double-numbered over a distance of 87 kilometers. At the village of Eager you cross US 60, the road from Globe and Phoenix to Socorro in New Mexico. Due to the higher altitude, the area here is more alpine, and less desert-like with small trees. In Alpine, US 180 turns east, leaving US 191on towards Douglas in the south. US 180 then continues for a few kilometers to the border with New Mexico. US 180 in New Mexico then continues toward Silver City in the southeast.
Beginning in 1931, the section between Holbrook and Springerville at Eagar was numbered US 260. In 1962 this section was numbered US 180. US 180 officially begins in Valle on State Route 64, but many maps show US 180 continuing north to the Grand Canyon. Between 1960 and 1971, US 180 between Flagstaff and Holbrook was gradually replaced by the construction of I-40. Only the Winslow, Joseph City, and Holbrook bypasses took a little longer, common for road construction in the western United States, because these places owed their existence to through traffic, which would otherwise bypass the places. Since 1981, US 180 between Flagstaff and Holbrook has been completely replaced by I-40 when the Joseph City bypass opened.
The road is very quiet, there is still a lot of traffic in Flagstaff, but only 400 vehicles per day drive past the Petrified Forest NP. The double numbering with US 191 is not much busier with 1,500 vehicles. Only 640 vehicles cross the New Mexico border every day.
US 70 in Arizona
According to ehotelat, US 70 is a US Highway in the US state of Arizona. The road forms an east-west route in the east of the state, running from US 60 in Globe to the New Mexico border. The route is 200 kilometers long.
The road begins in Globe, a small town of 7,000 residents about 150 miles east of Phoenix on US 60, the Phoenix-Eagar road. The road then heads southeast, at an elevation of about 1,100 meters through a mountainous desert area. The road runs partially through the San Carlos Apache Indian Reservation. The road follows the course of the Gila River and descends slowly. After about 125 kilometers you pass through Thatcher, and shortly afterwards, in Safford, US 191 merges from Douglas in the south. Both roads are then double-numbered for about 15 kilometers, after which the US 191 turns north, towards Eager, parallel to the border with New Mexico. The road then rises again to about 1,400 meters above the Peloncillo Mountains. Near Franklin, the road then crosses the border into New Mexico, after which US 70 continues in New Mexico towards Las Cruces.
US 70 was created in 1926, and was double-numbered west of Globe with US 60. In the 1930s, the route in Arizona was extended and shortened several times. In 1932, US 70 was shortened to Clovis, and then was no longer in Arizona. In 1934, US 70 was extended west to Mecca, California, and shortened again to Ehrenburg in 1965. In 1969 the route was further shortened to Globe.
US 70 was of little importance after I-10 was built through Arizona, and only a short section between Pima and Thatcher has been widened to 4 lanes.
The road is generally not too busy, but due to the lack of roads in the region, there is quite a bit of traffic. To the south, the nearest road is I-10 at Tucson, which quickly runs about 150 miles more southwest. The road has about 3,000 vehicles at its quietest point between Globe and Safford, but has 22,000 vehicles at its busiest point at the double- numbering US 191. Only 1,500 vehicles cross the New Mexico border every day.
