Boulder Creek Path Extension Project

Boulder County Transportation, in partnership with the City of Boulder and Colorado Department of Transportation, is evaluating plans to extend the Boulder Canyon Trail further west along SH 119/Boulder Canyon Drive. The planned extension will result in a 10-foot wide trail from the current terminus near Fourmile Canyon Drive west to Chapman Drive, including a potential grade-separated connection to Fourmile Canyon Drive and the Betasso Preserve open space. The trail extension will improve safety for cyclists, pedestrians and motor vehicles traveling in Boulder Canyon. 

The project is funded through a State of Colorado grant, Boulder County Sales Tax, and a contribution by the City of Boulder. 

Feasibility Report:

In 2011, a study was completed to determine feasibility and approximate costs of the trail extension. This study is the basis for the current conceptual plans. The study was used to determine possible grant sources. It also provided preliminary plans and drawings of path design alternatives.

DRAFT Concept Plans:

The draft concept plans will be posted soon. They will be available for review at the Jan. 21, 2016 open house (see below).
