I-70 Glenwood Canyon safety protocols updated for upcoming season

Travel Advisory

May 28, 2025 - Colorado - Glenwood Canyon returns to normal thresholds ahead of peak travel months

Statewide — The Colorado Department of Transportation, in partnership with the U.S. Forest Service (USFS), National Oceanic and Atmospheric Administration (NOAA), the U.S. Geological Survey (USGS) and others, has updated safety protocols for Interstate 70 through Glenwood Canyon ahead of the 2025 summer travel season. These adjustments come after the 2020 Grizzly Creek Fire and subsequent years’ mudslides prompted additional safety measures to protect both motorists and crews traveling on I-70 through Glenwood Canyon.

In collaboration with Glenwood Canyon stakeholder agencies, it has been determined that there is a reduced threat level compared to previous years, based on indicators such as burn scar recovery and debris flow potential. Officials are projecting normal conditions in Glenwood Canyon for the upcoming summer. As a result, CDOT and its partners will adjust inclement weather protocols.

While stakeholder agencies, such as USGS, NOAA and USFS, will continue to monitor and alert CDOT concerning weather forecasts and conditions, the following updated safety protocols will be implemented throughout Glenwood Canyon starting in June 2025. These adjustments aim to ensure continued safety and preparedness as travel volume increases in peak summer travel periods.

Glenwood Canyon Safety Protocols

Flash Flood Watch I-70 protocol

Previously, under the I-70 Protocol, maintenance crews were stationed at the two primary closure points along I-70 at mile point 133 (Dotsero) and MP 116 (Glenwood Springs) when a Flash Flood Watch was issued. Moving forward, CDOT crews will implement standard traffic control measures at all closure points and will actively monitor conditions in Glenwood Canyon using cameras and personnel on the ground.

Flash Flood Warning I-70 protocol

Under the previous protocol, I-70 through Glenwood Canyon would close when a Flash Flood Warning was issued, with maintenance crews coordinating with the Colorado State Patrol. This summer, however, crews will continuously monitor conditions and keep I-70 open—along with rest areas and the recreation path—as long as it remains safe. This also includes maintaining access for both private and commercial rafting groups.

Motorists planning to travel on I-70, visit rest areas or use the recreation path in Glenwood Canyon should pay attention to road conditions on COtrip.org and the COtrip Planner App, as well as nearby overhead I-70 digital message boards and weather forecasts. In the instance an extended closure is expected, CDOT will send information to stakeholders.
