The highway enters West Jordan and widens to four lanes as it curves east into 9000 South, just before crossing the Mountain View Corridor.

After crossing 5600 West, the route heads downhill within the Salt Lake Valley.

The route ends at SR-210 near the mouth of Little Cottonwood Canyon, where the valley gives way to the Wasatch Range.

[3] State Route 177 was designated in 1965 along 9000 South between SR-68 and US-89 in Sandy, in order to provide access to the new I-15.

[5] As of 2008[update], the extension was built to 5600 West,[2] though it was not yet state-maintained,[1] and the remainder, plus a continuation to SR-111, was in the area's regional transportation plan.
