Utah State Route 176 (1933–1969)

Utah State Route 176 was a state highway in entirely within the cities of Salt Lake City and South Salt Lake in Salt Lake County, Utah, United States. It mainly functioned as an alternate route for US-89, US-91, and I-15 traffic that provided access to industrial areas of the two cities and avoided urban cross-traffic in Downtown Salt Lake City. The original route followed 900 South west from State Street (Salt Lake County) (concurrent US-89 and US-91) to 300 West and then traveled north on 300 West to meet US-89 and US-91 again at South Temple (or, later, at North Temple). The route was subsequently changed to follow 300 West only: it followed 300 West all the way from 3300 South (SR-171) to North Temple (traffic from either I-15 or State Street could reach the southern end along short stretches of SR-171).

Before the mid-20th century, 300 West was confusingly known as Second West, based on the idea of numbering streets from the nearest corner of Temple Square rather than just from the southeast corner (which is the only origin recognized by the modern Salt Lake County addressing system).
