State Route 171 is a state highway in the Salt Lake City metropolitan area in northern Utah that runs from SR-111 in Magna in the west side of the city to Interstate 215 in the East Benches in the eastern part of the city. In its sixteen-mile span, the route is named "3500 South" and "3300 South".

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.

History

3300 South/3500 South was added to the state highway system west of State Street on April 24, 1916, along with 8400 West north to 2100 South (which was already a state highway); on November 13 of that year, East 3300 South to a connection with the old Territorial Road in Parley's Canyon (also already part of the system) became a state highway. [http://books.google.com/books?id=pZUAAAAAMAAJ Fourth Biennial Report, State Road Commission, 1915 and 1916] , pp. 214, 218] In 1919, when the state legislature redefined the state road system to include only a short list given in the law and any federal aid projects, West 3300 South remained as part of the Lincoln Highway, [cite UTSR law|year=1919|quote=(e) The Lincoln Highway from the Utah-Wyoming State line, via Echo Canyon, Echo, Coalville, Hoytsville and Parley's canyon to Salt Lake City; thence westwardly via Magna, Garfield, Tooele, Stockton, St. John, Clover, Johnson's Pass, Granite Mountain and Ibapah to the Utah-Nevada State line.] and became part of SR-4 and US-40 in the 1920s,Rand McNally [http://www.broermapsonline.org/members/NorthAmerica/UnitedStates/NorthernRockies/Utah/ Auto Road Atlas] , 1926] but East 3300 South was given back to the county until 1935. That year, the legislature created State Route 171, occupying that street from State Street (by then designated SR-1 and US-91) east to Wasatch Boulevard (just east of present I-215). [cite UTSR law|year=1935|quote=Route 171. From a point on route 1 south of Salt Lake City east via Thirty-third South Street to Wasatch Boulevard.] SR-210 was created in 1941, beginning at SR-4 (now I-80) at the mouth of Parley's Canyon and running south on Wasatch Boulevard to Little Cottonwood Canyon; [cite UTSR law|year=1941|chapter=34|quote=Route 210. From route 4 in Parley's Canyon via Wasatch Boulevard and Little Cottonwood Canyon to Alta.] that route was truncated in 1945, and the portion on Wasatch Boulevard between SR-171 and SR-4 became an extension of SR-171. [cite UTSR law|year=1945|quote=Route 171. From route 1 south of Salt Lake City east via Thirty-third south Street to Wasach [sic] Boulevard thence northerly to route 4 in Parley's Canyon." "Route 210. From route 152 at seventieth south street southeasterly via twentieth east street and Little Cottonwood Canyon to Alta.] 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 the interchange with I-215 at Wasatch Boulevard (as I-215 had replaced the purpose of Wasatch Boulevard).Utah Department of Transportation, [http://www.udot.utah.gov/main/f?p=100:pg:5285268476414239680:::1:T,V:1348, Highway Resolutions] : PDFlink|1= [http://www.udot.utah.gov/main/uconowner.gf?n=200609190943571 Route 171] |2=863 KB, updated November 2007, accessed May 2008]
