2025 CDOT Rock Wall Mitigation
The Colorado Department of Transportation will begin work to stabilize the rock face above US Highway 550 between Durango and Silverton starting Monday, May 12. Rockfall mitigation work will take place along Coal Bank Pass (Mile Points 56 to 60), approximately 11 miles south of Silverton and seven miles north of Purgatory Ski Resort. Motorists should plan for full stops and up to 20-minute delays throughout the duration of the project.
Attention bicyclists, you must obey all traffic laws and 24/7 temporary traffic signals located on US 550 between Purgatory and Silverton. For the safety of cyclists, vehicles and construction crews, you must come to a full stop at the temporary work zone signals and only proceed when the light is green. The work zones are single lane and only allow enough space for one-way single lane traffic. Disobeying the signals is against the law for both cyclists and motorists. Please wait for your turn and follow traffic laws to avoid head-on accidents or injury. Cyclists shall obey traffic laws - you’re a vehicle too!
