[edit] Route description
From SR-111 in Magna, the highway (known as 3500 South) runs due west until its junction with SR-68, where it veers to the northeast before again straightening out to the west. This is where it becomes 3300 South. SR-171 passes in this general direction while running through Magna, West Valley City, South Salt Lake, Millcreek and Salt Lake City.
[edit] History
When SR-171 was formed in 1935, it went from SR-1 (US-91 along State Street, now US-89) to Wasatch Boulevard (just east of present day I-215) via 3300 South. In 1945, the route was extended to SR-4 (US-40, replaced by I-80) via Wasatch Boulevard, which had been added to the state highway system in 1941 as part of SR-210.[3][4] In 1962, SR-171 was extended west to SR-111 in Magna, replacing SR-4 (which was moved to present I-80 as SR-2); in 1965, the eastern terminus was reverted to Wasatch Boulevard (as I-215 had replaced the purpose of Wasatch Boulevard), and subsequently changed to I-215 in 1971. The route has not changed since.[2]
