This weekend is the last chance to drive one of Utah's best-known mountain roads until spring. The Utah Department of Transportation (UDOT) will close the Alpine Loop — State Route 92 — for the winter at 7 a.m. on Monday, November 2, UDOT announced on October 29. It is UDOT's first seasonal winter road closure of the year, and it cuts the through route between American Fork Canyon and Provo Canyon in Utah County until the snow clears.

The closed section is the high mountain stretch of SR-92 between Pine Hollow in American Fork Canyon and Aspen Grove, above Sundance. UDOT's Timpanogos area office puts the gate points at Milepost 14 at Pine Hollow and Milepost 22 at Aspen Grove — roughly eight miles of narrow, winding canyon road that climbs from about 5,000 feet at the mouth of American Fork Canyon to a crest of about 8,000 feet below Mount Timpanogos. From 7 a.m. Monday, no vehicle can travel through between the two canyons on the loop.

What stays open — and how to reach Sundance and Tibble Fork
The closure does not cut off the canyon destinations themselves. UDOT said drivers can still reach Sundance via Provo Canyon and Tibble Fork Reservoir via American Fork Canyon, weather and road conditions permitting — what closes is only the high connecting section over the top. UDOT's seasonal roads page lists SR-92's status in October 2026 in exactly those terms: 'SR-92 American Fork Canyon/Alpine Loop — will close for the season on Monday, November 2, at 7 a.m.'

"UDOT closes several high-elevation roads each winter to keep drivers safe when heavy snow and rapidly changing conditions make travel hazardous," the department's news release says. "These roads remain closed through the winter, with reopening dates dependent on weather, snowpack and maintenance needs." In practice, UDOT says its seasonal roads stay closed typically from November through May or June, depending on the weather — so the Alpine Loop's summer season, which runs from late May or early June, is now over.
The Alpine Loop is not closing alone. UDOT's seasonal page shows SR-190, Guardsman Pass between Brighton and Park City, closing for the season on Friday, October 30 at 8 p.m., and UDOT's Timpanogos office noted that Wasatch County is also closing the Cascade Springs upper gate, near the South Fork of Deer Creek, on Monday, November 2 — the same morning as the Alpine Loop. Other high routes, including SR-150, the Mirror Lake Highway, remain open until further notice.
Why this road matters beyond the scenery
The Alpine Loop is a paved scenic byway through the Uinta-Wasatch-Cache National Forest, famous for autumn colour and for the trailheads, picnic sites and campgrounds along it. It is not a freight route — UDOT restricts vehicles longer than 30 feet, including truck-and-trailer combinations, because of its narrow lanes, blind curves and tight hairpin switchbacks, and directs large vehicles between Utah Valley and Heber Valley to Provo Canyon (US-189) instead. There is no toll for driving through on SR-92; a US Forest Service recreation pass, $10 for three days, is required only if you park to use trailheads, picnic sites or campgrounds, UDOT says.
For residents of Utah County and the Heber Valley, though, the loop is a working shortcut as well as a scenic drive, and its closure pushes all canyon-to-canyon traffic onto US-189 through Provo Canyon for the next six months or more. It also marks the practical start of winter driving season on Utah's mountain roads: the same UDOT pages that carry the closure carry the avalanche warnings for Provo Canyon, where UDOT triggers avalanches that threaten the road and closes it fully while mitigation is in progress.
What happens next
Anyone planning a last drive has until 7 a.m. Monday, November 2 — and should check conditions first, because the closure is timed for the arrival of the snowy months and high-country weather can change fast. UDOT advises drivers to check the UDOT Traffic website for current conditions and its seasonal roads page for closure updates before heading into the mountains. The loop will reopen only when weather, snowpack and maintenance allow — on UDOT's usual pattern, in late May or early June.
