Boulder Creek Path Extension Project

Boulder Creek Path Extension Project

Boulder County Transportation, in partnership with the City of Boulder and Colorado Department of Transportation (CDOT), will extend the Boulder Canyon Trail further west along SH 119/Boulder Canyon Drive. CDOT will complete the work as part of their reconstruction of SH 119 between Boulder and Nederland. The project will start in April or May 2019. The 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. View final designs. 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.

Construction and Trail Impacts:

The contractor plans to work on the trail starting in late April/early May 2019. Work will last until Spring 2020.

Expect weekday closures of the trail during construction to accommodate for rock blasting. No weekend or holiday work is planned, so the trail will be open then. For more information:

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.
