Welcome to Little Cottonwood Canyon (SR‑210) in winter — one of the most beautiful and challenging mountain roads in Utah. This guide explains how closures, avalanche control, and traction rules typically play out and how to plan safe, efficient trips to Alta and Snowbird.

Key Takeaways

• Check live road status and travel times on the Little Cottonwood Canyon page.
• Traction requirements (chains or 4×4 with snow tires) are posted by UDOT during storms.
• Expect intermittent closures for avalanche control and clean‑up after heavy snowfall and strong winds.

Chains and 4×4 Requirements

During active storms and icy periods, UDOT may require:

• 4×4/AWD with true winter tires, or
• 2WD with tire chains.

Watch the Restrictions chip and message signs on the dashboard for real‑time rules. Carry chains if you don’t have dedicated winter tires.

Avalanche Control & Closures

Avalanche control work often occurs in the early morning after overnight snow or during prolonged events. Reopen times vary with snow totals, wind, and visibility. Plan ahead and be flexible on big powder days.

Parking & Powder Day Strategy

Alta and Snowbird lots can fill early on big storms. Verify parking details before leaving, and consider UTA ski bus options. Start early, leave space, and use pullouts safely to chain up.

Use The Dashboard Effectively

Check the Travel panel for current status and delay vs free‑flow. Use UDOT and resort cams for visibility and wind. Snow totals and wind chips in the resort quick facts give a fast read on conditions.
