[edit] History notes
Most of this is from the history PDF. Opening years are from [1].
- May 12, 1931: added to the state highway system from South Bountiful (Parkin Overpass) to North Farmington Junction (89/273)
- 1935 (ca.): Parkin Overpass built
- A 1937 map shows that SR-1 where bypassed was US-91 Alternate. US-89 is very strange on that map - Wyoming takes it south via present US-189 to east of Evanston, while Utah has it beginning at either Ogden or Brigham and running with US-91 to Logan, and ending at the Idaho state line.
- 1953: extended north to South Layton on ex-SR-1 (ex-SR-1 between Lagoon Junction and North Farmington Junction became part of SR-49); swapped with SR-1 between South Bountiful and North Farmington Junction
- May 8, 1961: anything?
- 1962: extended south on ex-SR-1 to Becks; the rest of ex-SR-1 there became SR-169; I-15 opened from Becks to North Bountiful in 1962
- 1966: extended north on ex-SR-1 to Utah Hot Springs (89/126)
- November 23, 1966: I-15 opened from South Layton to SR-79 in Ogden[2]
- March 7, 1969: truncated to Shepard Lane and extended along ex-local Shepard Lane; Shepard Lane to North Farmington Junction became SR-272; North Farmington Junction to Kaysville became SR-273, which extended over ex-local 200 North; Kaysville to South Layton became local; South Layton to Roy became southern extension of SR-84; Roy to Utah Hot Springs became SR-50
- 1971-72: I-15 upgraded from North Bountiful to Lagoon Junction
- 1977: I-15 upgraded from Lagoon Junction to South Layton
- May 20, 1977, truncated at south end to South Bountiful (was US-89 to the south)
- SR-50 became SR-26 where not eliminated by US-89
- August 26, 1977, SR-84 became SR-126 south of Utah Hot Springs
- February 9, 2001, truncated at south end and absorbed SR-131; part of ex-SR-106 became SR-68, and the rest to Bountiful City
- March 9, 2001, SR-273 absorbed SR-272
