U.S. Route 191 is a major north-south state highway through the eastern part of the U.S. state of Utah. The present alignment of US-191, which stretches from Mexico to Canada, was created in 1981 through Utah. Previously the route had entered northern Utah, ending at US-91 in Brigham City, but with the completion of I-15 it was truncated to Yellowstone National Park and re-extended on a completely different alignment. In addition to a large portion of US-163, this extension absorbed several state routes: SR-33, most of SR-44, and SR-260.

Route description

US-191 enters Utah on Navajo Nation land and crosses mostly desolate parts of the state. The largest cities served by US-191 are Moab, Price and Vernal. The highway nears the 10,000-foot level in 2 places in Utah, over Indian Summit near Price and again while crossing the Uintah Mountains near Vernal. It leaves Utah at Flaming Gorge Reservoir. US-191 directly or indirectly serves a number of parks in eastern Utah: Monument Valley Navajo Tribal Park, Glen Canyon National Recreation Area, Hovenweep National Monument, Natural Bridges National Monument, Capitol Reef National Park, Canyonlands National Park, Arches National Park, Dead Horse Point State Park, Dinosaur National Monument, and Flaming Gorge National Recreation Area.

Three portions of US-191 in Utah have been designated National Scenic Byways. Between U.S. Route 163 and State Route 95, US-191 forms part of the Trail of the Ancients. From Moab to Vernal, US-191 is a portion of the Dinosaur Diamond Prehistoric Highway. The Flaming Gorge-Uintas Scenic Byway begins at Vernal and follows US-191 to Flaming Gorge. The state has designated the portion from Helper to Duchesne as the Indian Canyon Scenic Byway, a Utah Scenic Byway.

Three portions of US-191 in Utah have restrictions on trucks and other large vehicles. Between the junctions with State Routes 46 and 279, vehicles wider than convert|15|ft|m|2 are required to have two police escorts. Between Vernal and the Wyoming State line, vehicles longer than convert|95|ft|m|0 are required to have two certified pilot escorts. Vehicles heavier than convert|20000|lb|kg|-3 per axle are prohibited on Flaming Gorge Dam.cite web

History

When US-191 was created in 1926, it did not enter Utah, only running from Idaho Falls northeast to Yellowstone National Park.Bureau of Public Roads, parallel to US-191, the latter route was removed from Utah in the early 1970s,Fact|date=June 2008 and by 1980 it only existed north of Yellowstone.

In cooperation with Montana, Wyoming, and Arizona, the Utah Department of Transportation submitted an application to the American Association of State Highway and Transportation Officials (AASHTO) for an extension of US-191. In Wyoming, it would replace US 187 - a single-state route, which was against current AASHTO policy - and then follow Wyoming Highway 373 to the state line. The portion in Utah replaced several state routes - State Route 260 from Wyoming to Greendale Junction, the majority of SR-44 to US-40 in Vernal, and SR-33 from US-40 in Duchesne to US-6 near Price. After overlapping US-6 past Green River, the routing followed and replaced a large portion of US-163 to a junction southwest of Bluff. Between Bluff and Mexican Water, Arizona, US-191 followed a newly-constructed road across the Navajo Indian Reservation, and then replaced State Route 63, still mostly inside the reservation, to I-40 at Chambers. (It has since been continued along former US 666 to Douglas on the Mexican border.)

Arizona to US-6

The road from Bluff north via Monticello, Moab, and Valley City to Thompson (a station on the Denver and Rio Grande Railroad) became a state highway in 1910.Utah Department of Transportation, [http://www.udot.utah.gov/main/f?p=100:pg:5285268476414239680:::1:T,V:1348, Highway Resolutions] : PDFlink|1= [http://www.udot.utah.gov/main/uconowner.gf?n=200609121817391 Route 9] |2=3.66 MB, updated September 2007, accessed May 2008] To connect this road with the rest of the state highway system, a road from Valley City northwest via Floy to Green River was added in 1912, as was a connection from Thompson to via Cisco to Colorado.Utah Department of Transportation, [http://www.udot.utah.gov/main/f?p=100:pg:5285268476414239680:::1:T,V:1348, Highway Resolutions] : PDFlink|1= [http://www.udot.utah.gov/main/uconowner.gf?n=200609121733533 Route 8] |2=16.8 MB, updated September 2007, accessed May 2008] An extension from Monticello southeast to Colorado was added in 1913, and in the 1920s most of these roadways were assigned numbers: State Route 8 went from Green River via Floy, Valley City, Thompson, and Cisco to Colorado, and State Route 9 began at Valley City and extended south via Moab to Monticello and east to Colorado.Rand McNally [http://www.broermapsonline.org/members/NorthAmerica/UnitedStates/NorthernRockies/Utah/ Auto Road Atlas] , 1926]

With the creation of the U.S. Highway system in 1926, SR-8 and SR-9 each received a second designation, US-50 and U.S. Route 450 respectively.Bureau of Public Roads, , [http://www.geocities.com/usend7079/Crescent/index.htm Utah] , c. 1934]

Although no significant changes were made to SR-9 or SR-47 after 1935, the signed U.S. Highway numbers changed several times. First, in the late 1930s, U.S. Route 160 replaced US-450, continuing to enter the state east of Monticello and end at Crescent Junction. Then in about 1970, US-163 was designated along the entire length of SR-47 from Arizona to Monticello, and replaced US-160 north to Crescent Junction; at the same time, US-666 was extended from Cortez, Colorado over US-160 to a new terminus at US-163 in Monticello.Fact|date=June 2008 The 1977 renumbering saw the elimination of SR-9 and SR-47, by then no longer signed due to the concurrent U.S. Highway designations. The final change (except for the 2003 renumbering of US-666 to US-491) came in 1981, when US-191 replaced US-163 north of a junction near Bluff. South of this intersection, US-191 followed a route that not formerly existed as a state highway. The Bureau of Indian Affairs (BIA) completed this road across the Navajo Indian Reservation, and San Juan County built the short piece north of the San Juan River, in time for the extension of US-191. After the BIA granted an easement to Utah for the road, formerly BIA Route N12(23)2&3 , in 1988, it was added to the state highway system the next year.

US-6 to US-40

The road connecting Colton on SR-8 (US-50, now US-6) with SR-6 (US-40) in Duchesne became a state highway in 1910. The southwest end was moved from Colton to Castle Gate in 1912 ,Utah Department of Transportation, [http://www.udot.utah.gov/main/f?p=100:pg:5285268476414239680:::1:T,V:1348, Highway Resolutions] : PDFlink|1= [http://www.udot.utah.gov/main/uconowner.gf?n=200609140937301 Route 33] |2=3.71 MB, updated October 2007, accessed May 2008] and in 1927 it was numbered State Route 33. [cite UTSR law|year=1927|quote=33. From Castle Gate northeasterly to Duchesne.] Few changes were made to the roadway, and in 1981 it became part of US-191.

US-40 to Wyoming

The road from SR-6 (US-40) in Vernal north to SR-43 in Manila, where one could continue to Wyoming, was added to the state highway system in about 1918 as a forest highway project, [http://books.google.com/books?id=pZUAAAAAMAAJ Fifth Biennial Report, State Road Commission, 1917-1918] , pp. 24-25] completed in 1926,Utah Department of Transportation, [http://www.udot.utah.gov/main/f?p=100:pg:5285268476414239680:::1:T,V:1348, Highway Resolutions] : PDFlink|1= [http://www.udot.utah.gov/main/uconowner.gf?n=200609140948051 Route 44] |2=8.92 MB, updated October 2007, accessed May 2008] and numbered SR-44 in 1927. [cite UTSR law|year=1927|quote=44. From Vernal northerly to Manila.] It was the only state road connecting Daggett County's seat, Manila, with the rest of the state, yet parts remained in an unimproved condition through the 1950s.Utah State Road Commission (Rand McNally), Utah Official Highway Map, 1956]

Several routes have been designated over the years to connect SR-44 to Flaming Gorge, a canyon on the Green River that lends its name to the Flaming Gorge Dam that US-191 now crosses the river on. The first was State Route 165, which would have begun at SR-44 south of Manila and headed east to the gorge. The state legislature added the proposed road to the state highway system in 1933, [cite UTSR law|year=1933|chapter=30|quote=(165) From junction with route 44 south of Manila easterly to Flaming Gorge.] but in 1935 it was deleted, and the number was reused to the west on a portion of Birch Creek Road. [cite UTSR law|year=1935|quote=Route 165. From a point on the Utah-Wyoming state line, Daggett County, southerly 5 miles.] Later, in 1941, the planned connection was redesignated as a state highway, this time State Route 220, [cite UTSR law|year=1941|chapter=34|quote=Route 220. From route 44 south of Manila easterly to and across Green River at a point near Flaming Gorge — approximately eight miles.] but in 1945 it was moved north, closer to the state line. [cite UTSR law|year=1945|quote=Route 220. From Linwood on route 43 easterly and parallel to the Utah-Wyoming state line approximately five miles to and across Green River.]

It was this alignment that was actually built, beginning at Linwood on SR-43 and proceeding east-southeasterly through a valley that is now flooded by the Flaming Gorge Reservoir's Linwood Bay.Utah Department of Transportation, [http://www.udot.utah.gov/main/f?p=100:pg:5285268476414239680:::1:T,V:1348, Highway Resolutions] : PDFlink|1= [http://www.udot.utah.gov/main/uconowner.gf?n=200609140947191 Route 43] |2=2.91 MB, updated October 2007, accessed May 2008, p. 5] SR-220 was deleted in 1957, but in its place was a new State Route 260 that began at Greendale Junction on SR-44 and headed northeast over the dam (then under construction) and to the state line. The legislature did not specify where it would intersect the border, [cite UTSR law|year=1957|quote=Route 260. From route 44 near Greendale northerly via Flaming Gorge dam to the Utah-Wyoming state line at a point either east or west of the Green River.] and the State Road Commission initially routed it along former SR-220 to Linwood.Utah Department of Transportation, [http://www.udot.utah.gov/main/f?p=100:pg:5285268476414239680:::1:T,V:1348, Highway Resolutions] : PDFlink|1= [http://www.udot.utah.gov/main/uconowner.gf?n=200609121731523 Route 3] |2=10.5 MB, updated September 2007, accessed May 2008, p. 31] However, the law was amended in 1963 to define the north end to be east of the reservoir, [cite UTSR law|year=1963|quote=Route 260. From route 44 near Greendale northerly via Flaming Gorge Dam to the Utah-Wyoming state line near Spring Creek Gap.] and soon the lake began to fill, cutting off the road to Linwood (and inundating that settlement).

XX1] By 1981 the new road was completed, and most of SR-44 and all of SR-260 were absorbed by US-191.Utah Department of Transportation, [http://www.udot.utah.gov/main/f?p=100:pg:5285268476414239680:::1:T,V:1348, Highway Resolutions] : PDFlink|1= [http://www.udot.utah.gov/main/uconowner.gf?n=200609191520261 Route 191] |2=5.94 MB, updated November 2007, accessed May 2008]
