Utah State Route 173
State Route 173 is a major east-west thoroughfare completely within Salt Lake County in northern Utah. From its western terminus at SR-111 it passes through the growing west side of Salt Lake County, eventually reaching US-89 in Murray.Route description
Starting at its western terminus in West Valley City, SR-173 heads east through West Valley City, passing by the USANA Amphitheatre. Continuing east, the route enters Kearns, passing by the Utah Olympic Oval and Kearns High School before entering Taylorsville and crossing the Bangerter Highway. Shortly thereafter, the route crosses under I-215 and passes Taylorsville High School at the Redwood Road continuous flow intersection. The route continues eastward, crossing a canal before descending a steep hill to the Jordan River as it enters Murray and shifts slightly to the north. East of its single-point urban interchange with I-15, the route passes under the Union Pacific, UTA's FrontRunner, and TRAX rail lines as they run close together at the approach to Murray Central Station, and Cottonwod Street passes over the TRAX line and SR-173 simultaneously on a high viaduct. Emerging from the trench under the railroads, SR-173 passes Intermountain Medical Center and Murray High School before ending at US-89 near Murray City Park.
The entire route is included as part of the National Highway System.History
The State Road Commission created State Route 173 in 1965, following 5300 South between SR-68 and SR-271, in order to improve access to I-15. The state legislature extended it west to SR-111 in 1969. In 2012 reversible lanes were installed between Bangerter Highway and 1900 West.Major intersections
