Severe whiteout conditions led to multiple crashes and the closure of Interstate 70 near the Eisenhower Tunnel in Colorado on March 4, 2025. With near-zero visibility and slick roads, the stretch of highway became extremely dangerous for drivers, forcing authorities to shut down westbound lanes for several hours.
What Happened?
- Multiple Crashes: Several vehicles, including passenger cars and semis, were involved in separate accidents between mile markers 221 and 216.
- Complete Closure: Westbound I-70 was shut down at Georgetown (mile marker 228), forcing drivers to turn back or wait in standstill traffic.
- Treacherous Conditions: Heavy snowfall, high winds, and blowing snow created whiteout conditions, making it nearly impossible for drivers to see the road ahead.
- Injuries Unconfirmed: Officials have not released details on injuries, but emergency responders were dispatched to assist stranded motorists.
How Authorities Responded
- Rescue and Cleanup: Law enforcement and road crews worked for hours to clear vehicles and assist drivers stuck between the crashes and the closure point.
- CDOT Road Crews: Plows and sanding trucks were deployed to clear snow and improve traction before reopening the highway.
- Reopening of I-70: After several hours of delays, westbound lanes reopened around 6:30 p.m., though conditions remained snow-covered and hazardous.
Why Whiteout Conditions Are So Dangerous
A whiteout occurs when heavy snow and strong winds create a wall of blowing snow, making it almost impossible to see anything in front of a vehicle. These conditions are particularly dangerous because:
- Drivers can’t see the road lines or other vehicles.
- Snow and ice reduce traction, increasing the risk of losing control.
- Sudden slowdowns or stops can lead to multi-car pileups.
Staying Safe in Whiteout Conditions
If you must drive in a whiteout, follow these tips to stay safe:
Slow down and increase following distance.
Turn on your headlights and hazard lights to improve visibility.
Avoid sudden braking—ease off the gas instead.
If conditions get too dangerous, pull over safely and wait it out.
The Bigger Picture
Colorado’s I-70 corridor through the Rockies is notorious for sudden snowstorms. With spring approaching, fluctuating temperatures can cause rapid snowfall and dangerous driving conditions. Travelers should always check weather and road conditions before heading into the mountains.
