CO Highway 119, locally known as the Diagonal, connects Boulder to Longmont and travels through Gunbarrel and Niwot. Currently there are 45,000 vehicles a day that travel along the corridor.
Northwest Area Mobility Study
The Northwest Area Mobility Study (NAMS) is a collaborative effort that addressed significant cost increases and delays associated with building and operating the 41-mile Northwest Rail commuter rail line from Longmont to Denver. The study concluded with elected officials, the Regional Transportation District (RTD), Colorado Department of Transportation (CDOT) and 13 area jurisdictions and agencies reaching consensus on transit priorities in the region.
NAMS priorities include:
- US 36 Bus Rapid Transit (BRT): Determine the remaining FasTracks BRT funding/scope for the US 36 corridor and complete corresponding commitments.
- Priority Arterial BRT Corridors: Conduct advanced planning and design of arterial BRT on CO 119, CO 7 and US 287. New funding must be identified for these and other arterial BRT corridors.
- US 36 to Denver Reverse Commute: Work with CDOT to evaluate the reverse commute traffic between Denver Union Station and US 36 (e.g. Boulder-bound a.m. travel and Denver-bound p.m. travel). For the I-25 downtown Express Lane, evaluate alternatives to ease reverse commute traffic.
- B Line (formerly known as Northwest Rail): Annually evaluate strategies to accelerate implementation of the B Line while recognizing it is a long-term project. Evaluate the feasibility and cost of constructing the line in segments.
- Additional Arterial BRT: Consider implementing additional arterial BRT/enhanced bus corridors (South Boulder Road, 120th Avenue and Colorado 42/95th Street)
RTD is currently working on a number of BRT-related projects, including:
- Proceeding with planning efforts on Colorado State Highway 7.
- Proceeding with planning efforts for CO 119 (the highest prioritized BRT corridor).
- Beginning a BRT Feasibility Study for US 287 between Longmont and US 36.
Commuting Solutions is working with local and regional partners to identify funding for these and other arterial BRT corridors. CO 119 and Highway 7 received TIP funding from DRCOG to proceed with the next level of environmental planning.
Northwest Mobility Study Areas
The Cities of Lafayette and Louisville are working together to envision the future of State Highway 42 (also known as 95th Street, CO 42 or Courtesy Road) for people to walk, bike, ride transit or drive.
The Colorado State Highway 7 (CO 7) corridor between Brighton and Boulder is well positioned to develop as a corridor of local livability and multimodal regional access.
In March 2019, the Northwest Mayors & Commissioners Coalition released a letter reconfirming their commitment to Northwest Rail and Peak Service exploration.
Boulder County, in coordination with stakeholders, regional partners and members of the public, is starting a multi-phased re-envisioning process of US 287.
