Utah State Route 173

Starting at its western terminus in West Valley City, SR-173 (which is routed on 5400 South) 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 (SR-68) 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 (taking the name 5300 South). East of its single-point urban interchange with I-15, the route passes under the Union Pacific, UTA's FrontRunner, and TRAX (Blue and Red) 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 (the largest hospital in the Intermountain West) and Murray High School before ending at US-89 (State Street) near Murray City Park.

The entire route is included as part of the National Highway System.[2]

The State Road Commission created State Route 173 in 1965, following 5300 South between SR-68 and SR-271 (US-89), in order to improve access to I-15. The state legislature extended it west to SR-111 in 1969.[3] In 2012, reversible lanes, referred to locally as "flex lanes", were installed between Bangerter Highway and 1900 West.[4]
