US 287


US 287 Bus Rapid Transit Feasibility Study Map

In 2014, the Northwest Area Mobility Study (NAMS)  identified US 287 as a strong candidate for implementing BRT and found that US 287 had the highest projected ridership among the other corridors the study analyzed. As a result, the NAMS recommended that US 287 should be prioritized for implementation. Since the NAMS, the area around US 287 has experienced continued population and employment growth, further increasing travel demand. This BRT feasibility study will build off the NAMS study and build a multi-modal vision for the BRT implementation on US 287.

US 287 Bus Rapid Transit Feasibility Study

Boulder County, in coordination with stakeholders, regional partners and members of the public, is starting a multi-phased re-envisioning process of US 287.

This first phase of the study closely examines the feasibility of Bus Rapid Transit (BRT) implementation on the US 287 corridor between the City of Longmont and the City of Broomfield, including Erie, Lafayette, Longmont and Broomfield, to address the growing congestion and travel demand in the area. The study will recommend the type and location of capital investments that will enhance transit travel times on US 287 through conducting an analysis that will assess traffic patterns, current transit operations and infrastructure, vehicle queue lengths, opportunities for intersections treatments and a Station Areas Toolkit.

The study will also identify potential funding sources and provide the framework for the next steps for the implementation of the BRT along US 287.

Phase 1: Feasibility Study

In Phase 1, work will include community involvement, establishing a corridor vision, existing conditions analysis, BRT Feasibility and cost estimates, a station toolkit and setting up funding.

Phase 2 and Long-term Objectives

In phase two, and long-term, work will include concept design, prioritization of improvements, design, environmental analysis, federal and other funding and implementation.  Traffic signals planning will also be an important element in future plans.

Project Partners

Since this project is regional in nature, Boulder County has developed a Stakeholder Working Group to closely collaborate with the planning team throughout the feasibility study process. The Stakeholder Working Group consists of agency representatives from the City and County of Broomfield, the City of Longmont, the Town of Erie, Commuting Solutions, Transport, the City of Lafayette, the Regional Transportation District, the Colorado Department of Transportation, the Federal Highway Administration, the Federal Transit Administration and economic development entities.

The Stakeholder Working Group will meet regularly throughout the planning process and will be key collaborators on the study.

Key Action Items of Corridor Project

This corridor project is part of Boulder County’s Transportation Master Plan. Action items include:

  • Prioritize moving people
  • Advance Northwest Area Mobility corridors
  • Explore funding options and innovative partnerships

Cost Estimates

The project could cost $56 million.
