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.

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.
