Colorado I-70 Road Conditions & Closures: Real-Time Updates

I-70 can experience closures or slowdowns due to:

• Winter & Avalanche Control: Snowstorms, high winds, icy roads, and scheduled avalanche mitigation operations (especially near Georgetown and Vail Pass) frequently cause closures. Avalanche control typically occurs at night or early morning and lasts 1-4 hours
• Traffic Incidents: Accidents, vehicle breakdowns, and pileups contribute to congestion.
• Construction Projects: Scheduled maintenance and improvements, such as work near Floyd Hill, may lead to temporary roadblocks.

If you prefer to avoid the stress of winter driving, Peak 1 Express provides safe, reliable shuttle services with professional drivers experienced in navigating I-70 during all weather conditions.

Weekend ski traffic also causes major delays—eastbound Sunday afternoons (1pm-7pm) and westbound Friday afternoons (3pm-8pm) can add 2-3 hours to drive times

Colorado uses tiered traction requirements on I-70. “Code 16” or “Traction Law” requires 4WD/AWD vehicles OR 2WD with winter tires/chains. “Code 17” or “Passenger Vehicle Chain Law” requires ALL vehicles (including 4WD) to have chains or approved traction devices. Violating these laws can result in fines. Peak 1 Express shuttles are always equipped to meet any traction requirements.

Limited alternatives exist, and most add significant time. If the Eisenhower Tunnel closes, Loveland Pass (US-6) can be used, but it’s a narrow road above 11,990 feet that often closes in poor weather. For western closures, some detour through Steamboat Springs via US-40/Highway 131 (adding 2-3 hours). For Glenwood Canyon closures, Independence Pass is the only alternative but closes entirely October-May.

The heaviest traffic typically occurs:

• Fridays (westbound) and Sundays (eastbound)
• Weekends from 11 AM to 4 PM
• Holidays and peak ski season (December–March)

If you’re driving yourself, follow these tips:

• Ensure your vehicle has either 4WD/AWD with adequate tread (minimum 3/16 inch) OR 2WD with winter tires AND chains
• Carry an emergency kit with blankets, food, water, and a shovel.
• Check weather and road updates before heading out. Keep your gas tank above half-full in case of long closures. Practice installing chains before your trip.
