Talk:Utah State Route 106

History notes
Most of this is from the history PDF. Opening years are from.
 * 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
 * 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
 * June 22, 2001, ex-SR-272 part of SR-273 transferred to Farmington City


 * May 8, 1961 would have been the shifting of the southern terminus from Main Street to 200 West. The Bamberger Railroad had just been removed, and a road was built on the old right of way. That's what put the southern terminus at the interchange on US 89, and in fact the bridge at that interchange is the original 1930s railroad bridge.--Roadguy2 (talk) 22:02, 8 December 2018 (UTC)

South end 1962-1977
I was looking through the highway resolutions, and I noticed what seems to be a contradiction in the highway resolutions. In 1962, SR-1 was moved to I-15. The old route from the Becks interchange to the north Bountiful interchange (today's US 89 routing) were designated as SR-169. But at the same time, SR-106 was extended south from the Parkin Junction overpass to the Becks interchange as well.

For what it's worth, I couldn't find any documents in the 106 resolutions explicitly saying "106 extended south", but the legislative description was updated to indicate a southern terminus at I-15.

So was US 89 from Becks to Parkin Junction legislatively designated as a SR-106/169 concurrency? That isn't something UDOT typically does or did. Plus it's a useless overlap anyway, as both routes terminated at the same place. --Roadguy2 (talk) 21:59, 8 December 2018 (UTC)
