CO 7 Between Brighton & Boulder | Preliminary & Environmental Engineering

About the Project

Colorado State Highway 7 (CO 7) between Brighton and Boulder is a vibrant, diverse, and emerging transportation corridor within the north Denver Metropolitan Area. Originally a two-lane rural highway, rapid population and employment growth within the corridor’s communities and new and developing urban centers have transformed its travel patterns and functionality. Today, it is an evolving major east-west regional arterial connecting residents to jobs, activity centers, and the regional transportation system.

Multiple planning and feasibility studies have established the corridor’s future multimodal vision, including an integrated plan of Bus Rapid Transit (BRT) improvements supported by multimodal (roadway, bicycle and pedestrian) infrastructure and transit supportive land development at planned station areas. Robust BRT services with supporting infrastructure are envisioned for a well-connected regional corridor serving all modes of travel, providing safe and reliable travel, and linking existing and emerging urban centers.

Today, vestiges of the rural highway remain. Advancements to transition the vision into design and construction are needed to address current needs, manage ongoing growth, and prepare for the future.

The CO 7 Coalition, in coordination with the CDOT, secured funding to advance the previous planning into preliminary design. A $10 million Regional Share Funding application for the CO 7 Preliminary and Environmental Engineering Project was approved for the Denver Regional Council of Governments (DRCOG) 2020-2023 Transportation Improvement Program.

This project will develop preliminary design plans, allowing municipalities, counties, agencies, and developers to rapidly invest in corridor improvements.

In collaboration with the CO 7 Technical Advisory Committee (TAC) , comprised of technical staff from the CO 7 Coalition membership and participants, a Corridor Development Plan (CDP) was prepared to establish the overall work program and oversight framework for the project. Because the allocated funding is insufficient to fully achieve  objectives across the corridor, a plan was needed to optimize the project while strategically preparing for future and additional funding. The CDP fulfills this purpose. It will help ensure the project fulfills its goals, is responsive to agency expectations, is effectively delivered with accountability, maximizes the use of the previous studies, and provides the best possible use of the allocated funds.

Working closely with the TAC, the formulation of the CDP entailed a thoughtful and collaborative process of identifying the goals of the project and aligning, evaluating, and prioritizing elements of the recommended improvements, called proposed actions, for inclusion in the project.  These proposed actions represent independent functional components of the corridor’s vision, such as constructing an improved intersection or building the multimodal section between two intersections. Combined with an overall delivery framework, including budget, schedule, and resource planning, the CDP enables the project to move forward into execution.
