Colorado Ski Season Camera Monitoring
Track mountain pass conditions in real-time with 135,000+ traffic cameras across 600+ sources. Monitor the I-70 corridor, where peak traffic through the Eisenhower Tunnel can exceed 6,000 vehicles per hour, leading to metering and multi-hour delays.
VIEW CAMERAS →Every Colorado ski season brings the same challenge: navigating the I-70 corridor between Denver and the mountains. Weekend traffic jams, sudden storms, and chain law activations can turn a 90-minute drive into a 5-hour ordeal. Visual monitoring is your best defense; the 2024-2025 winter saw a 40% increase in I-70 closures due to weather and accidents. Live traffic cameras give you the intelligence you need to time your departure, choose alternative routes, and avoid the worst conditions.
This guide covers the critical camera locations for ski season travel, from Denver's foothills through the major passes to Summit County and beyond. Whether you're headed to Vail, Breckenridge, Winter Park, or Steamboat, you'll know exactly what to monitor before hitting the road.
I-70 Cameras You Should Bookmark
The I-70 mountain corridor between Denver and the Eisenhower Tunnel is the most heavily traveled ski route in North America. These cameras show the conditions that matter most for weekend warriors.
Floyd Hill / Veterans Memorial Tunnels
MP 243-247 — First major elevation gain from Golden. Westbound backups start here on Saturday mornings. Cameras show queue length before tunnels and road conditions through the S-curves.
Eisenhower-Johnson Tunnels
MP 216, Elevation 11,158' — Highest point on I-70. East and west portals show weather transition, tunnel traffic flow, and chain law enforcement staging. These cameras tell you if conditions flip from clear to whiteout.
Vail Pass Summit
MP 190, Elevation 10,662' — Second major pass between Summit County and Vail Valley. Summit cameras show wind conditions, visibility, and snowplow activity. Critical for understanding conditions west of the tunnel.
Genesee / Lookout Mountain
MP 253-256 — Final descent into Denver from the mountains. Eastbound Sunday afternoon cameras show the infamous return traffic that can add 2-3 hours to the drive home.

Monitor Conditions Now →I-70 Critical Segments
Understanding the geography of the corridor helps you interpret camera feeds and plan timing around trouble spots.
I-70 Critical Segments
Floyd Hill to Georgetown (MP 247-228) — Steep grade with tight curves. Worst westbound Saturday morning backups occur here. Crashes shut down lanes for hours. Monitor Floyd Hill, Bakerville, and Georgetown cameras before departure.
Eisenhower Tunnel (MP 216) — Weather dividing line. Conditions west of the tunnel can be completely different from Summit County. East portal camera shows wind/snow approaching from west. Traction law often activates here first.
Copper Mountain to Silverthorne (MP 195-205) — Summit County gauntlet with resort exits, merge lanes, and elevation changes. Saturday westbound congestion peaks here as traffic splits toward different resorts.
Vail Pass (MP 180-190) — Highest sustained grade on I-70. Runaway truck ramps indicate steep descent. West side cameras show conditions approaching Eagle/Glenwood Springs.
Alternative Mountain Corridors
When I-70 cameras show red brake lights or complete closures, these alternative routes become critical escape valves.
US-285 Kenosha Pass
Elevation 10,001' — Alternative to I-70 for reaching Fairplay, Buena Vista, and southern ski areas. Less traveled but more exposed to wind. Snow drifts close the road faster than I-70. Cameras show conditions through South Park basin. Best for Copper Mountain, Breckenridge, and Monarch Mountain access when I-70 is jammed.
US-40 Berthoud Pass
Elevation 11,307' — Direct route to Winter Park Resort. Two-lane highway with avalanche mitigation zones. Cameras show approach from Empire and summit conditions. Colorado's second-highest continuously maintained pass. Chain law enforcement is stricter than I-70.
SH-82 Independence Pass
Elevation 12,095', Seasonal — Aspen access, closed November through late May. When open, cameras show spectacular high-alpine conditions. Not a ski season alternative, but useful for spring skiing access and fall color timing.
Traction Law Enforcement Zone
I-70 MP 133 to MP 259 (Morrison to Dotsero) falls under Colorado's traction law. When activated, all vehicles must have:
- Passenger vehicles: Winter tires with 3/16" tread OR all-season tires with M+S rating AND chains/AutoSock
- 4WD/AWD: Adequate tread depth (3/16" minimum)
- Commercial vehicles: Chain requirements per CDOT regulations
Cameras at enforcement points show trooper staging areas and vehicle inspections. Fines start at $130 and increase if you cause traffic delays. Watch for electronic message boards showing traction law status.

View Cameras →Ski Resort Traffic Patterns
Each major resort has its own traffic signature based on parking capacity, lift operating hours, and access road configuration.
Saturday Morning Westbound (6 AM - 11 AM)
- Floyd Hill cameras show backup starting as early as 6:30 AM on powder days
- Eisenhower Tunnel queues form by 8 AM on holiday weekends
- Copper Mountain/Frisco exits create merge conflicts visible on MP 195-205 cameras
- Vail exit (MP 176) shows congestion when resort parking fills
Sunday Afternoon Eastbound (2 PM - 7 PM)
- The infamous "Vail Merge" at MP 180 where two lanes become one
- Eisenhower Tunnel east portal backs up 5-10 miles by 3 PM
- Georgetown (MP 228) cameras show where traffic finally starts moving
- Floyd Hill descent (MP 247) is last chokepoint before metro area
Resort-Specific Corridors
- Breckenridge: SH-9 cameras from Frisco show southbound queue
- Keystone: US-6 from I-70 exit 205 shows access road
- Vail: Frontage road cameras show village approach congestion
- Winter Park: US-40 corridor from Empire shows full route
- Steamboat: US-40 to Rabbit Ears Pass, then SH-131 north
Storm Approach Visualization
Add cameras west to east on your map to visualize weather systems approaching Denver. Start with Vail Pass summit, then Eisenhower Tunnel west portal, then Georgetown, then Floyd Hill. Watch storms move across your camera timeline to predict when conditions will hit your location.
Pre-Trip Camera Check for Ski Day
Build a systematic routine for checking conditions before every mountain drive.
Check West Portal Cameras First
Start at Eisenhower Tunnel west portal and Vail Pass summit. These show incoming weather systems before they reach Summit County. Heavy snow or low visibility here means conditions will worsen east as you drive.
Monitor Your Specific Route Cameras
Add cameras for every exit and merge point you'll use. Copper Mountain exit? Watch MP 195. Breckenridge? Add SH-9 cameras. Build a camera sequence that matches your exact drive.
Look for Plow Activity
Active snowplows visible on cameras mean CDOT is treating roads but also indicate accumulation. Plows with flashing lights create moving bottlenecks. Plan extra time if you see multiple plows.
Check Traction Law Enforcement Points
Cameras near chain stations (MP 216, MP 228) show if troopers are inspecting vehicles. Long queues of cars being checked add 30-60 minutes to drive time.
Time Your Departure Using Queue Length
Floyd Hill westbound cameras show exact backup length on Saturday mornings. Count the number of camera views showing stopped traffic to estimate delay. If backups extend past Idaho Springs (MP 240), consider waiting 1-2 hours.
Build Your Camera Route
Create a custom camera sequence for your specific ski area drive with 135,000+ camera feeds.
Start Monitoring →Weather Monitoring Beyond Cameras
Live cameras show current conditions, but combining them with other data sources gives you predictive power.
CDOT COtrip Integration COtrip.org provides chain law status, road closure alerts, and travel times between camera locations. Cross-reference camera views with COtrip alerts to understand why you're seeing delays. Cameras show the visual, COtrip explains the cause.
When Traction Law Activates Electronic message boards visible on cameras display traction law codes:
- Code 15: Passenger vehicles need chains or adequate tires
- Code 16: Commercial vehicles need chains
- Red flags at camera locations mean chain law is active
Camera Indicators of Deteriorating Conditions
- Brake light halos (visibility dropping below 100 feet)
- Windshield wiper streaks on camera lenses (heavy precipitation)
- Lane markings disappearing (snow accumulation exceeding 1-2 inches)
- Emergency vehicles with chains deployed (road treatment falling behind)
- Empty frames (cameras covered by blowing snow)

Frequently Asked Questions
How early should I check cameras before driving to the mountains?
Check cameras 2-3 hours before departure to see developing conditions, then again immediately before leaving. Weather systems move fast in the mountains — conditions can change completely in 30 minutes. Set up your camera sequence the night before so you can quickly scan all critical points on departure morning.
What's the best time to avoid I-70 traffic on ski weekends?
Westbound Saturday: leave before 6 AM or after 11 AM. Eastbound Sunday: leave before noon or after 7 PM. The 2-6 PM eastbound window is worst. Use cameras to watch queue formation in real-time and adjust timing. Powder days shift all patterns 1-2 hours earlier.
Do cameras work at night during ski season?
Most I-70 cameras have infrared or low-light capabilities. You'll see headlights, brake lights, and snowplow strobes clearly. Useful for predicting morning conditions by watching overnight plow activity. Some high-elevation cameras lose visibility in heavy snow regardless of lighting.
Which alternative route is fastest when I-70 is closed?
US-285 over Kenosha Pass is the only winter alternative to reach Summit County. US-40 over Berthoud Pass serves Winter Park only. For Vail or west, there's no alternative — you wait for I-70 to reopen. Check cameras on alternatives before committing; they close faster than I-70 due to less maintenance.
How do I know if I need chains just by looking at cameras?
Look for these signs on camera feeds: cars pulled over installing chains, trooper enforcement staging areas, electronic message boards showing traction law codes, snow accumulation hiding lane markings, or all vehicles moving at 20-30 MPH. If cameras show any of these, you need traction equipment even if the law isn't officially activated yet.
