U.S. Route 191
U.S. Route 191 (US 191) is a north–south highway in the Western United States and a spur of parent route U.S. Route 91 that has two segments. The southern segment runs for 1,211 miles (1,949 km) from Douglas, Arizona on the Mexican border to the southern part of Yellowstone National Park. The northern segment runs for 442 miles (711 km) from the northern part of Yellowstone National Park to Loring, Montana, at the Canada–US border. Unnumbered roads within Yellowstone National Park connect the two segments. The highway passes through the states of Arizona, Utah, Wyoming, and Montana.
The highway was designated in 1926 and its routing has changed drastically through the years. The modern US 191 bears almost no resemblance to the original route, which was primarily in the state of Idaho. Most of the current route of US 191 was formed in 1981. Since the extensions in the 1980s and 1990s, U.S. Route 191 is much longer than its parent route to which it no longer connects, and it is one of the longest U.S. three-digit routes.
US 191 begins in Cochise County, Arizona at a signaled intersection with Arizona State Route 80 (SR 80) and Historic U.S. Route 80 (Historic US 80) near Douglas. The highway then proceeds north past Bisbee Douglas International Airport passing through the hamlets of Elfrida and McNeal. Near Sunizona, US 191 intersects with the western terminus of SR 181. US 191 then curves west for 7.5 miles (12.1 km) before turning northwest through Sunsites and Cochise. US 191 intersects Interstate 10 (I-10) near Cochise at a trumpet interchange (I-10 Exit 331). US 191 and I-10 run concurrent for 20.9 miles (33.6 km) around Willcox. In Willcox, I-10/US 191 serves as the northern terminus for SR 186 at Exit 340. The city itself is served by the Willcox I-10 Business Loop, which begins and ends at I-10/US 191 southwest and northeast of the city. In Bowie Junction at Exit 352, US 191 leaves I-10 and heads north, exiting Cochise County and entering Graham County. US 191 has a ten-mile (16 km) overlay with US 70 east of Safford. The route links to State Route 366 (SR 366) and SR 266 to the south of Safford. The route between Springerville and Morenci was designated a National Scenic Byway and given the name of Coronado Trail Scenic Byway, as this approximates the path taken by Francisco Vásquez de Coronado between 1540 and 1542. This is a very dangerous mountain road with many sharp curves and little or no shoulders on steep cliffs. North of the byway, the highway is the primary route to access Canyon de Chelly National Monument. US 191 traverses the Navajo Nation before entering Utah.
US 191 has a detached business route in Arizona, running from SR 80/Historic US 80 in Douglas, along Pan American Ave to the US Customs/Immigration Port of Entry at the border with Mexico. The portion of this route between its intersection with SR 80 near Douglas and the intersection with Interstate 40 at Sanders was formerly the major Arizona portion of US 666. Part of US 191 through the Navajo Nation is designated by the Arizona Department of Transportation as the Tse'nikani Flat Mesa Rock Scenic Road.
US 191 serves the eastern half of the state. The road enters Utah in a remote portion of the Navajo Nation. The highway passes through mostly desolate areas of eastern Utah. Several portions are National or Utah Scenic Byways. It passes through Bluff, Blanding, Monticello (the seat of San Juan County), and Moab, the largest city in southeastern Utah and the seat of Grand County. It connects with U.S. Routes 6 and 50 as it joins Interstate 70 going due west through the town of Green River, home of the John Wesley Powell Museum. A few miles west of town it splits off with US 6 and continues north between the San Rafael Reef to the west and Book Cliffs to the east through Emery County. It then enters the historic coalfields of Carbon County, passing through Wellington and Price, the largest city in Eastern Utah, home to the USU Eastern Prehistoric museum, and historic Helper, the main stop for Amtrak between Provo, Utah and Grand Junction, Colorado. In addition to linking many rural towns in Utah to I-70 and US 40, the highway served to interconnect several national and state parks for tourism, namely Canyonlands National Park, Arches National Park, Bears Ears National Monument, and Dead Horse Point State Park. The highway exits Utah just after crossing the Flaming Gorge Reservoir.
US 191 enters Wyoming near a geographical feature known as Minnie's Gap, just east of Flaming Gorge National Recreation Area. The route proceeds north through rugged desert country following an alignment mostly constructed during the 1970s, to a junction with Interstate 80 at Exit 99, just west of Rock Springs. This segment of the route is known locally as "East Flaming Gorge Road."
The route is then concurrent with Interstate 80 eastward for approximately five miles (8.0 km), passing just north of Rock Springs. US 191 diverges northward at Exit 104, following the former route of US 187. Traveling through high desert country, the route passes through Eden, Farson, and Pinedale before meeting US 189 at Daniel Junction. Continuing north, the road traverses increasingly mountainous terrain, entering the Bridger-Teton National Forest and passing through the small community of Bondurant before descending through the narrow Hoback River Canyon to an intersection with US 26 and US 89 at Hoback Junction. The route then follows the Snake River valley northward to Jackson. US 191 is concurrent with US 189 between Daniel Junction and Jackson, and with US 26 and US 89 between Hoback Junction and Jackson.
North of Jackson, US 191 soon enters Grand Teton National Park, running concurrently with US 26 and US 89. The highway meets US 287 at Moran Junction, inside the park; US 191, US 89, and US 287 are concurrent north of Moran, but the highways are not signed. Continuing through forested, mountainous country, the route passes through the John D. Rockefeller Jr. Memorial Parkway before ending at the South Entrance of Yellowstone National Park. While US 191 and other U.S. Routes are officially discontinuous through the park, some commercially produced maps show these highways running inside Yellowstone National Park itself along its unnumbered roads and across the Wyoming–Montana state line.
