Projects Impacting Cycling

Sugarloaf Road Construction – No uphill cycling between CO 119 and Betasso Road

Starting May 2, 2022, crews will begin constructing new retaining walls along the first 2,000-feet of Sugarloaf Road up from CO 119/Boulder Canyon. In order to complete this work, Sugarloaf will be reduced to one-lane in this stretch. Traffic signals will be used to control alternating traffic on the available lane. Due to the steep incline, cycling will not be allowed in the uphill direction through the construction zone Cycling will be allowed in the downhill direction. The project is anticipated to be completed in October 2022, weather permitting. Learn more.

Thank you for following restrictions! We apologize for any inconvenience.
