Driving up State Route 210, the only road through Little Cottonwood Canyon, can be an adventure in itself—especially on a powder day. Locals have a fitting name for that infamous traffic jam of glowing red brake lights: the "Red Snake." With smart planning and the right information, you can conquer the congestion and get to Alta or Snowbird safely and with less stress.

How to Beat the Red Snake Traffic

The Red Snake coils up when thousands of skiers and snowboarders try to head up the canyon at the same time, usually between 7:00 AM and 10:00 AM on weekends and powder days. Travel times can swell from 30 minutes to over two hours. To avoid the worst of it, your strategy is simple: travel when nobody else is.

How to Prepare for the Traction Law

From November 1st to May 1st, Utah's Traction Law is often in effect on SR-210. This is a legal requirement enforced by UDOT to keep the road safe and open. Ignoring it can get you a hefty fine and, worse, turned around at the base of the canyon.

Here’s a quick breakdown of what your vehicle needs:

Vehicle TypeTire Requirement
4WD/AWDM+S (Mud and Snow) or 3PMSF (Three-Peak Mountain Snowflake) tires
2WD3PMSF (Three-Peak Mountain Snowflake) tires on all four wheels
2WD with Standard TiresMust carry and be prepared to install chains on your drive tires.

Always check your tires before the season kicks off. You can find the "M+S" or the three-peak mountain snowflake symbol on the sidewall.

Your Pre-Trip Checklist for Canyon Travel

Before you start your engine, a few minutes of research can save you hours of sitting in traffic.

  1. Check the UDOT Traffic App: This is your best friend. It gives you real-time road status, tells you if the traction law is on, and reports any road closures.
  2. View Live Traffic Cameras: Our site has live camera feeds from multiple spots along SR-210, so you can see exactly how bad the Red Snake is.
  3. Check the Avalanche Forecast: The Utah Avalanche Center posts daily forecasts. High danger can trigger road closures for control work, which often happens in the early morning.

What is Little Cottonwood Canyon Known For?

While famous for "The Greatest Snow on Earth®," the canyon is a year-round destination.

How to Stay Safe in the Canyon

Safety isn't just a recommendation in Little Cottonwood Canyon; it's a fundamental part of the culture. The same forces that deliver legendary powder also create some of North America’s most active and dangerous avalanche paths.

What is Interlodge?

Interlodge is a critical safety protocol unique to Little Cottonwood Canyon, enacted during periods of extreme avalanche danger. When Interlodge is declared, it becomes illegal for anyone to be outside. All residents and guests must stay indoors while avalanche mitigation teams use explosives to safely trigger avalanches, clearing the slide paths above the road and villages.

Interlodge isn't a suggestion; it's the law. Violating it comes with hefty fines and puts you and safety crews in extreme danger. An event can last for a few hours or, in a massive storm cycle, a couple of days.

How to Use Avalanche Forecasts

Your single most powerful tool for staying safe is information. The Utah Avalanche Center (UAC) issues a detailed daily avalanche forecast that is required reading. It uses a simple, color-coded danger rating from Low (Green) to Extreme (Black) to give you an at-a-glance idea of the day's risk. For a deeper understanding of historical snow data, consider reading the full analysis from the Utah Avalanche Center.
