SR-210 is the only road to Snowbird and Alta — 13.6 miles from the mouth of the canyon in the Salt Lake Valley, climbing through some of the most avalanche-exposed terrain of any highway in the country. Live UDOT cameras and alerts on the whole climb, below.

Little Cottonwood is a working highway with real avalanche control, real winter tire law, and — starting soon — a real toll. Here's what UDOT actually enforces.
UDOT counts 64 avalanche paths crossing SR-210, and more than half the highway sits under avalanche threat. Closures for avalanche control, sometimes with little notice, are a normal part of a canyon winter — not an emergency exception.
Utah requires snow tires or chains in the canyon for that entire window, and UDOT can restrict travel further to snow tires, chains, or 4-wheel drive only when conditions call for it. Follow UDOT Cottonwoods and the signs at the canyon mouth — restrictions can change within the hour.
UDOT's Little Cottonwood Canyon plan adds a peak-period toll (proposed around $25–$30 on busy ski days, not year-round) and more frequent buses — every 10–20 minutes instead of every 30 — as part of a longer-term plan that also includes a proposed 8-mile gondola. Phase 1 details were still being finalized as of spring 2026; check UDOT's own Cottonwood Canyons page for what's actually in effect this season.
The cameras and alerts above are the stationary view, the UDOT feed you would check before you leave the valley. In the MileCheck app, your exact mile marker and the nearest camera follow you up the canyon, hands-free on CarPlay and Android Auto.
Closures and incidents on SR-210 show on the map above as red and orange markers, from UDOT. See every UDOT camera on the Utah cameras page, or the US closures map for everywhere else.
Yes, by state law, from November 1 to May 1 every year. UDOT can tighten that to chains or 4-wheel drive only when conditions require it. Check the live cameras above for the road surface before you commit to the climb.
Snowbird's base is 7,760 feet, Alta's is 8,530 feet — both up SR-210, 13.6 miles from the canyon mouth in the Salt Lake Valley.
Not yet as a fixed daily charge, but UDOT's approved plan adds a peak-period toll on busy ski days as part of a phased rollout, alongside more frequent bus service. Check UDOT's Cottonwood Canyons page for what's actually running this season.
MileCheck shows your exact mile marker in real time on SR-210 up the canyon, plus the nearest camera and any alert on your route. Runs on CarPlay and Android Auto. The mile marker works without a signal.
