Spanning 11.6 miles (18.7 km), it connects Powder Mountain Ski Resort and the towns of Liberty and Eden with Utah State Route 39 in Ogden Canyon in Weber County.

State Route 158 begins at Eden Junction, its intersection with SR-39 at the Pineview Dam which is at the top of Ogden Canyon.

[4] Continuing north, the route passes the Wolf Creek Golf Resort before entering the narrow, steep canyon on its climb to Powder Mountain.

The road to Powder Mountain is one of the steepest state highways in Utah with an average grade of approximately 14% over 5 miles (8.0 km).

[9] In order to maintain continuity in the state highway system, SR-162 absorbed SR-163 the following year, resulting in SR-162 stretching from Eden Junction through Liberty to Hyrum.
