Denver, CO – A major mountain travel disruption unfolded Sunday night as eastbound Interstate 70 was closed at the Eisenhower Tunnel due to inclement weather and multiple crashes. The Colorado State Patrol announced the shutdown just after sunset, urging drivers to delay travel or seek alternate routes until conditions improve.
According to officials, deteriorating weather in the high country—combined with slick roads and reduced visibility—contributed to a series of incidents that forced crews to halt all eastbound traffic through the tunnel. The closure affects one of Colorado’s busiest mountain corridors, frequently used by commuters, truckers, and weekend travelers returning toward the Front Range.
No timeline has yet been provided for reopening the roadway. CDOT and CSP crews are working to clear disabled vehicles and respond to weather-related hazards before allowing traffic to resume. Motorists traveling through Summit County or attempting to return from mountain destinations may experience significant delays.
Drivers are being advised to reroute using U.S. 6 over Loveland Pass if conditions allow or delay travel entirely until the interstate reopens. Winter driving conditions are expected to persist overnight, with snow, freezing temperatures, and gusty winds contributing to hazardous road surfaces across the I-70 mountain corridor.
Authorities emphasize the importance of checking updated road conditions through COTrip.org, especially as additional closures or chain laws may be required.
Travelers are urged to pack winter gear, reduce speeds, and plan for rapidly changing mountain weather throughout the evening.
