An avalanche slammed into U.S. Highway 50 westbound on Sunday, shutting the road between Monarch Peak Campground and County Road 237B near Monarch Pass. Traffic is being rerouted, and drivers are advised to slow down while responders and heavy equipment clear snow and debris. The shutdown cuts into a crucial east-west route between Gunnison and Salida and is expected to add serious travel time for anyone trying to cross the Sawatch Range.
CDOT Confirms Closure And Detour
According to the Colorado Department of Transportation, westbound US 50 is closed while crews respond to the slide, and a detour with slower speeds is in place on the approaches. CDOT also operates a long-running avalanche control program at Monarch Pass and maintains remote systems and control shelters to trigger and clear snow above the highway, as outlined on the Colorado Department of Transportation project page.
Avalanche Forecasts And Mitigation
The Colorado Avalanche Information Center monitors conditions across the Sawatch zone and issues forecasts and field reports that help time mitigation work and closures. Monarch Pass is frequently subject to controlled releases and natural slides during winter storms, so drivers should be ready for intermittent stoppages when the weather moves in. For forecasts and observations, see the Colorado Avalanche Information Center.
Plan Ahead If You Are Heading Over The Pass
Drivers traveling to Gunnison, Crested Butte, Buena Vista or Salida should plan on delays, follow posted detours and build in extra time. The state traveler map and alerts at COtrip offer real-time closure updates, estimated reopening times and suggested alternate routes. Commercial drivers should also confirm chain law or traction requirements before entering the mountain corridor.
