State Route 150, also known as theMirror Lake Highway, is astate highway in theU.S. state ofUtah. It is named forMirror Lake, a picturesque lake that the highway passes along the way. It is also a USDA Forest Service Scenic Byway.[3]
The highway begins at the intersection of Main Street (SR-32) and Center Street inKamas and heads east on the latter as a two-lane undivided highway. Once exiting Kamas, the route dips southeast and continues as such until reachingSamak, where the road turns northeast briefly. Soon after, the highway turns south and southeast again. After continuing in a general southeast direction, the highway turns northeast and north and continues as such until reaching theWyoming border south ofEvanston.[4]
The road is the highest paved road in Utah when it crossesBald Mountain Pass at an altitude of 10,715 ft (3,266 m).[5]
During the winter months the road is closed to automobiles and is used by snowmobiles.
The state legislature designated SR-150 in 1933, running east fromSR-35 (nowSR-32) inKamas to theWasatch-Cache National Forest boundary.[6] In 1953, it was extended east and north viaMirror Lake to theWyoming state line.[7]
