Project Background

The Colorado Department of Transportation (CDOT), in partnership with the City and County of Broomfield (Broomfield), is conducting a multimodal and safety study to develop concepts to improve the US 287/120th Avenue corridor. The project aims to understand the impact of changing traffic patterns since the completion of the 120th Avenue Connection project as well as look for ways to improve multimodal capacity and address safety.

120th Avenue is an important regional corridor that has been identified for multimodal improvements in various plans and studies. The corridor has been identified as part of the High Injury Network and a Critical Corridor by the Denver Regional Council of Governments' in the Taking Action on Vision Zero Plan, illustrating the importance of this multimodal study to find design approaches to address the known deficiencies. In addition, the corridor is identified as a potential Bus Rapid Transit (BRT) corridor in the 2014 Northwest Area Mobility Study (NAMS) and the 2016 Broomfield Transportation Master Plan highlighting the need to study potential improvements that can support transit on the corridor.

Infrastructure gaps remain for pedestrians and bicycles that need to be addressed. Some of the pedestrian and bicycle deficiencies will be addressed as part of Broomfield’s 120th Sidewalk Infill Project in 2025, while other pedestrian and bicycle improvements are being studied as part of this effort.

CDOT and the City & County of Broomfield will look at options for improving access to transit facilities and operational improvements to increase the reliability of transit.

With a renewed emphasis and heightened awareness of safety and mobility of all users along busy corridors, including planning for vehicles, pedestrians, bicycles and transit, the US 287/120th Avenue Multimodal and Safety Study is an opportunity to create a vision and plan that recognizes the diverse needs of City and County of Broomfield residents, business owners, visitors and traveling public.


Project Location


Goals and Objectives

Join Broomfield and CDOT envision a future corridor that:

  • Builds on previous City and County of Broomfield, CDOT, and RTD studies and improvement efforts to develop a comprehensive plan that improves safety, operations, and equity for all modes of travel
  • Increases safety for all travelers
  • Improves accessibility of multimodal transportation facilities for all ages and abilities
  • Identifies multimodal transportation infrastructure gaps within the project area
  • Promotes 120th Avenue as a future Bus Rapid Transit (BRT) corridor

Public Outreach Opportunities for Residents

This project is a partnership between CDOT and the City and County of Broomfield. Between June and September 2022, Broomfield and CDOT sought input from the public about locations on the corridor with gaps in accessible multimodal travel options suitable for all ages and abilities, locations with safety challenges, areas on the corridor with severe traffic congestion and other travel related issues, and locations where overall multimodal options for residents needed to be improved.

The engagement survey and the interactive map for the initial phase of existing conditions public outreach are now closed.

New Public Engagement Opportunities for the Draft Corridor Improvement Alternatives

Broomfield needs your input to help identify improvements for areas along the US 287/120th Avenue Corridor (the corridor). The project team invites you to provide feedback on the conceptual alternatives that envision the most transformational changes to the corridor in an online survey that can be found at the end of this page. The new survey is open for public input May 15 through June 11 about the recommended alternatives report.

Over the last several months, the project team developed concept alternative improvements for locations throughout the corridor based on safety data, travel delay, other existing conditions data and your input from the initial phase. This effort resulted in alternative improvements ranging from minor, low-cost changes to a complete reimagining of how the certain areas of the corridor look and operate.

This project is a partnership between CDOT and the City and County of Broomfield. In June, Broomfield and CDOT began seeking input throughout the corridor project limits where you are experiencing gaps in accessible multimodal travel for all ages and abilities, safety challenges, or where overall multimodal options for residents can be improved.

The surveys for existing conditions along the corridor and the interactive map are now closed.

January 2023 Update: Public Input opportunities on the design alternatives will be occurring in the upcoming months and through the early summer. The project team will provide more updates as these dates are known.

Your feedback is important and the project team will keep you updated on when and where these opportunities will be occurring on this project page and the type of input being sought as the study progresses.


Public Outreach for Business Owners

The Colorado Department of Transportation in partnership with the City and County of Broomfield hosted three Virtual Project Q&A Panels for business owners regarding the US 287/120th Avenue Multimodal and Safety Study project on Wednesday, September 28, 2022.

During the virtual session, the project team provided a brief overview of the project, the goals and objectives for the study, as well as gave a brief overview of the upcoming alternative corridor improvement ideas.

The project team will be canvasing businesses along the corridor in the coming weeks to collect feedback on the draft alternatives and to encourage business owners to fill out the survey.

    CDOT and Broomfield are conducting a multimodal study for the US287/120th Avenue corridor. The project team needs your input to help identify the best design concepts for areas along the US 287/120th Avenue Corridor.  

    Beginning in the fall of 2022 and continuing through March 2023, the project team has been developing alternative improvements for locations throughout the corridor.  These design concepts were arrived at using public input collected through the summer and fall of 2022 about locations on the corridor that needed improvements.  In addition, existing conditions data outlining travel delay, safety issues, and other information contributed to the development of alternatives.  This effort resulted in concept designs ranging from minor, low-cost changes, to a complete reimagining of how certain areas of the corridor look and operate.

       The project team invites you to provide feedback on several alternatives that envision the most transformational changes in this survey.
