The highway then enters Salt Lake County and the Salt Lake City metropolitan area. SR-68 is one of two roads that connect Utah and Salt Lake Counties through a bottleneck in the Wasatch Front called Point of the Mountain, referring to the Traverse Mountains. The low-lying area through this neck is occupied by the former Denver and Rio Grande Western Railroad. SR-68 is routed on the western slope of the canyon, The other highway, I-15/US-89, is routed higher up Point of the Mountain. As the route enters Bluffdale on Redwood Road, it turns northeast and intersects with Mountain View Corridor again, then with SR-140; the Utah State Prison is located on this road east of the junction. SR-68 then turns north before crossing SR-154, commonly known as the Bangerter Highway. Soon reverting to two lanes, the route exits Bluffdale and enters Riverton, gaining two lanes in each direction as it passes SR-71. Continuing north, it enters South Jordan. It intersects with SR-175, SR-151, and SR-209, gaining one more lane in each direction beyond the latter intersection, and enters West Jordan and central Salt Lake County.
