 Since it was along the planned alignment for I-80, it became SR-2 (only a legislative designation that was never signed) in 1962, but the portion east of an interchange near the Salt Lake City International Airport was due to be bypassed by the Interstate, and so in 1966 that piece became State Route 267.State Route 176 was built in 1933 with federal aid and numbered in 1935, forming an alternate to US-89/91 through downtown Salt Lake City.Its original route began at South Temple Street and 300 West, and ran south on 300 West and east on 900 South to State Street.
