Bikeway Alignment

This video shows the proposed alignment of the nine-mile CO 119 Commuter Bikeway, including how the bikeway will connect to bus station areas and adjacent roadways. The proposed bikeway curves to avoid wetlands, irrigation infrastructure, and other obstacles. Bikeway underpasses are shown in brown.

Provide Input

Members of the Project Team are reviewing comments and questions received pertaining to the Preliminary Design plans. We are developing a Questions & Answers document. We will post the Q&A document to this website and email it to our mailing list, meeting attendees, and comment submitters. We anticipate sharing this document in early to mid-August.

About the Projects

Boulder County, CDOT and RTD are closely coordinating the dual transportation projects on the Diagonal Highway to improve mobility for Boulder, Longmont and adjacent communities. User-friendly connections between the commuter bikeway, improved pedestrian crossings, bus queue bypass lanes, BRT stations and Park-n-Rides will provide a variety of new transportation options in the CO 119 corridor that enhance safety, accessibility and equity, while reducing climate change and air quality impacts. 

The projects are the result of the 2014 Northwest Area Mobility Study (NAMS) and the 2019 Multi-Modal Planning and Environmental Linkages Study (PEL).
