 East of Redwood Road and the curve where it becomes 3300 South, SR-171 continues due east with two to three lanes in each direction, passing through South Salt Lake and Millcreek Township (and very small segments near former SR-181 bordering Salt Lake City), until its terminus.It is the first road south of 2100 South that provides access, for travelers from the west, to I-15 or other points east of the Union Pacific-"FrontRunner" railroad right-of-way; other roads in the area are blocked by Union Pacific's Roper rail yard.About two blocks east of the bridges carrying the Union Pacific railroad, "FrontRunner" railroad, and I-15 over the route, there is also a grade crossing with TRAX's Blue and Red lines next to Millcreek station.
