Utah's final seasonal roads open for summer adventure access

Alpine Loop and Mirror Lake Highway reopened Thursday, clearing Utah’s last seasonal roadblocks just in time for the holiday rush. With SR-92 in American Fork Canyon and SR-150 from east of Kamas to near the Wyoming border back online, UDOT said every seasonal state road was now open for the summer run-up.

That includes SR-39 over Monte Cristo, SR-65 through East Canyon, SR-190 and SR-224 at Guardsman Pass, SR-35 over Wolf Creek Summit, SR-153 to Mount Holly, and SR-148 at Cedar Breaks National Monument. The timing matters because these are not just pretty drives. They are the access routes that carry hikers, campers, anglers, mountain bikers, and ATV riders into some of Utah’s most-used high-country ground. UDOT’s seasonal-road pattern is straightforward: these corridors usually close through winter from November into May or June, depending on weather.

Mirror Lake Highway is one of the state’s most popular mountain routes, and it opens the door to the High Uinta Wilderness and the kind of weekend itinerary that can fill a whole truck bed with gear. The Alpine Scenic Loop starts at about 5,000 feet in American Fork Canyon and climbs to around 8,000 feet at the crest, which is why the road matters so much for Mt. Timpanogos views, Sundance access, and the recreation sites tucked along the Wasatch Range. Utah tourism officials have long treated these scenic byways as more than connectors between towns. They are the corridors that link travelers to public lands and the state’s biggest outdoor payoffs.

Even with the gates open, UDOT said conditions still deserve attention. Higher elevations can still hold muddy stretches after thaw, and Memorial Day traffic usually brings slower crawls through canyon and mountain corridors. UDOT spokesman John Gleason urged drivers to allow extra time and pay attention to changing conditions. For current status, UDOT points drivers to its traffic website, the free 511 service, and its traffic app. Non-state-maintained routes such as Nebo Loop and Pine Canyon are a different call entirely, and drivers need to check with the responsible agency, including the USDA Forest Service.

For anyone trying to piece together a first big summer loop, the message was simple: the state’s seasonal road network was finally online, but the season was opening with the same rules that always apply at elevation. The gates were up, and now the real test was how well everyone shared the road.
