Frequently Asked Questions — Utah Mountain Passes
Answers to common traveler questions regarding Utah pass road conditions, seasonal opening dates, and real-time UDOT 511 verification.
The highest paved mountain pass road in Utah is Bald Mountain Pass on Utah State Route 150 (Mirror Lake Highway) in the Uinta Mountains, reaching an elevation of 10,715 feet (3,266 m). Due to extreme high-alpine snow accumulation, it closes annually for winter.
Guardsman Pass (connecting Big Cottonwood Canyon, Park City, and Midway at 9,700 feet) typically closes in November following the first major winter storm and reopens in late May or early June once snow clearance is complete.
Parleys Summit on Interstate 80 is Utah’s highest priority winter highway and remains open year-round under almost all conditions. UDOT utilizes continuous snowplow fleets, automated anti-icing liquid sprayers, and overhead digital signboards. Chain and 4WD laws are strictly enforced during major storms.
