Boulder County Transportation, in partnership with the City of Boulder and Colorado Department of Transportation (CDOT), extended the Boulder Canyon Trail further west along CO 119/Boulder Canyon Drive. CDOT completed the work as part of the reconstruction of CO 119 between Boulder and Nederland.
The extension results in a 10-foot wide trail from the current terminus near Fourmile Canyon Drive west to Chapman Drive adding two new bike-friendly tunnels under the highway and approximately 3,500 feet of length to the trail. The trail extension improves safety for cyclists, pedestrians and motor vehicles traveling in Boulder Canyon.
