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.

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. The state legislature redefined all the state routes in 1927, and moved SR-8 to a direct Floy-Thompson cutoff, with both roads from Valley City to Floy and Thompson becoming SR-9. The Monticello-Bluff road was assigned State Route 47 and extended to Mexican Hat at that time and to the Arizona

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.

The state legislature added the proposed road to the state highway system in 1933, but in 1935 it was deleted, and the number was reused to the west on a portion of Birch Creek Road. Later, in 1941, the planned connection was redesignated as a state highway, this time State Route 220, but in 1945 it was moved north, closer to the state line.

's Linwood Bay. 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, and the State Road Commission initially routed it along former SR-220 to Linwood. However, the law was amended in 1963 to define the north end to be east of the reservoir, and soon the lake began to fill, cutting off the road to Linwood (and inundating that settlement). By 1981 the new road was completed, and most of SR-44 and all of SR-260 were absorbed by US-191.
