US 287

Background

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. 

US 287 Vision Zero Safety & Mobility Study

The US 287 Vision Zero Safety and Mobility Study is a collaborative effort to eliminate traffic-related fatalities and serious injuries, while addressing multimodal needs and opportunities. The study, finalized in December of 2023, analyzed safety and multimodal mobility along the US 287 corridor from Midway Boulevard in Broomfield to the Boulder/Larimer County line.

A detailed crash analysis was performed to identify crash trends and recommendations with the goal of eliminating all traffic fatalities and serious injuries along the corridor. A multimodal analysis was performed to determine the feasibility of a Walk-Bike Path adjacent to US 287. The study also identified gaps in the multimodal network to recommend strong connections to proposed BRT stations and existing and proposed key destinations. Finally, a planning-level environmental analysis was completed to provide an understanding of the environmental context and potential constraints within the corridor to be considered in future phases.

The project was led by Boulder County in partnership with the Colorado Department of Transportation (CDOT), City of Longmont, Town of Erie, City of Lafayette, City and County of Broomfield, Denver Regional Council of Governments (DRCOG), Regional Transportation District (RTD), Commuting Solutions, and members of the traveling public.

US 287 Bus Rapid Transit (BRT) Feasibility Study

April 2022 – In collaboration with many agency partners and local communities, Boulder County completed the US 287 Bus Rapid Transit Feasibility Study. (full study)(executive summary).

Recommendations include three bus service patterns with modifications to operations, stations, and intersections such as queue jumps that permit buses to utilize sections of right turn lanes to avoid congestion. The Phase I full study and executive summary detail these recommendations.

Project Overview: 

Over 18 months, the project team worked with technical staff, elected officials, and members of the public to create a vision for US 287 with Bus Rapid Transit (BRT) as a central component.

This corridor is important to serve people living, working, and traveling to/from the growing communities and key destinations along the corridor and beyond, offering connections with other local and regional transit routes. The US 287 corridor serves as the north/south spine of the Northwest Area Mobility Study’s (NAMS) network of regional BRT routes. Enhancing transit service along the corridor connects routes countywide and creates the opportunity to increase transit ridership throughout the region.

Community engagement played an important role in shaping this study, including the proposed recommendations and next steps to phase in regional and inter-regional transit improvements along the US 287 corridor. Through this planning process, we heard from the public that in addition to improved transit services, safety is important for all users alongside and crossing US 287.

The study recommends the type and location of capital investments that will enhance transit travel times on US 287. The study assesses and analyzes traffic patterns, current transit operations and facilities, vehicle queue lengths, intersections treatments, and created a Station Areas Toolkit. The study identifies potential funding sources and provides the framework for the next steps for the implementation of BRT along US 287.
