― Winter Maintenance Operations Alert ―

Expect delays on US 550 Coal Bank and Molas Passes tomorrow morning. 12/29/2022

CDOT will perform winter maintenance operations on US 550 between Durango and Silverton tomorrow morning. Crews will begin work at 6:30 a.m., triggering several slide paths and clearing snow on Coal Bank and Molas passes. Travelers can expect lengthy delays of an hour or more and should allow for extra travel time between Durango and Silverton. Motorists may also consider traveling before highway work begins. The operations will take place through much of the morning. 

With the prolonged storm system expected to remain in the area through early next week, travelers should be aware that additional maintenance work and safety closures may be implemented on southwest Colorado mountain passes over the next few days.
