CO 7 Multimodal Corridor from Brighton to Boulder
About the Project
Colorado Department of Transportation, Regional Transportation District (RTD) and local agencies are working on a planning initiative along CO 7 to improve traveler safety, make your trip more efficient and improve access to multimodal travel opportunities between Brighton and Boulder.
Through a $10 million Regional Share Funding grant from the Denver Regional Council of Governments, priority projects are being identified and early design plans developed to encourage quick investment in the transportation improvements amongst the municipalities, counties, agencies and developers along the corridor.

Segments
The limits of the project extend approximately 22 miles through eight local agencies. The decision to separate the corridor into segments was determined by the CO 7 - Corridor Development Plan (CDP). This is to maintain efficient implementation of design recommendations that are tailored to the needs of each segment.
Previous documentation efforts that have been completed and supplemental information can be found in the segment links below:
- Segment A: 28th Street to 63rd Street
- Segment B: 63 Street to US 287
- Segment C: US 287 to 119th Street
- Segment E to M: County Line Road to US 85
The Corridor Development Plan originally identified 13 segments to help plan and design improvements with defined endpoints. However, as planning shifts toward a corridor-wide approach, the emphasis on individual
segments has become less critical. The map below shows a continuous corridor with typical sections, transit starter service locations, trail connections, and mobility hubs.
To provide multimodal transportation improvements to optimize regional connectivity and mobility between eight jurisdictions, including three counties, in this rapidly growing and increasingly congested part of the northwest Colorado region.
- Advance multimodal improvements by promoting transit and incorporating multimodal infrastructure along the corridor
- Address existing and immediately foreseeable operational and safety needs
- Plan and prepare for the future by phasing in multimodal improvements that respond to anticipated growth
- Complement existing and planned infrastructure that benefits the multimodal system and addresses system deficiencies
- Leverage joint development opportunities
- Provide equity across the corridor by distributing project advancements fairly across the corridor

Transit Starter Service along CO 7
Official name of Starter Service is the Brighton to Boulder Flyer... Be on the lookout in Spring of 2026 for bus service along CO 7!
What is a Transit Starter Service?
Boulder County received a Federal Transit Administration grant to implement a transit starter service program from Boulder, Colorado to Brighton, Colorado. The program is intended to prove a need for transit service along an existing corridor that is lacking.
The Transit Starter Service route is set to include around 10 stations over 26.6 miles, serving communities within Boulder, Broomfield, and Adams counties and is expected to connect with other regional and interregional transit routes including:
- Flatiron Flyer
- FLEX
- Bustang
- US 287 Mobility Hub
- CDOT North I-25 Mobility Hub
