Corridor Planning Program

DRCOG formed the corridor planning program with the focus to advance planning for projects and priorities outlined in the 2050 Regional Transportation Plan with the goal of project implementation. As part of the program, DRCOG will fund and lead planning studies to advance infrastructure investment priorities along regional arterial corridors identified in the plan

Pilot Corridor Planning Program

DRCOG launched the corridor program as a pilot in fiscal year 2022 – 2023. Alameda Avenue and South Boulder Road were selected as the first two corridors. The two corridor studies started in 2023.  Learn more about each study and get involved on the study engagement sites:

2024 – 2027 Transportation Improvement Program Set-Aside Corridor Planning Program

Funding for the corridor planning program is included in a new set-aside budget in the 2024– 2027 Transportation Improvement Program. An estimated $3 million will be available for the full four-year set-aside program with $1.5 million expected to be spent during each two-year cycle.

2024 – 2025 Project Selection

DRCOG is selecting projects for the first two years of set-aside funding over the summer of 2023 through a letter of interest process. Key details about this process include:

  1. Project Eligibility: Corridors for this program must be included in the regional transportation plan. Read a list of eligible projects in the plan along with expected planning needs.
  2. Eligibility to Submit Letter of Interest: Letters of interest may be submitted by county and municipal governments in the DRCOG region, regional agencies including the Regional Transportation District, the Colorado Department of Transportation, DRCOG and groups or partnerships of local or regional agencies. Other organizations interested in the program should coordinate with relevant local jurisdictions to support the submission of a letter of interest.
  3. Required Conversations with DROG Staff: In addition to submitting a letter of interest, all jurisdictions will also need to schedule a call with DRCOG staff to discuss the proposed corridor. Contact  Nora Kern, Subarea and project planning program manager,, to schedule a meeting to discuss the proposed corridor. These conversations should take place before the end of the letter of interest window.
  4. Deadline: Letters of interest are due by August 25, 2023.

Additional details about the letter of interest and submittal instructions are included in the 2024–2025 Transportation Corridor Planning Set-Aside Letter of Interest Overview. Letters of interest can be submitted online through this form.

Regional Corridor Studies Web Map

DRCOG has developed a new web map to track ongoing planning efforts for the 2040 Regional Roadway System for the Transportation Improvement Program.Regional partners including local and county jurisdictions, the Colorado Department of Transportation and the Regional Transportation District will lead the studies. The web map‘s intent is to inform regional partners, local jurisdictions, DRCOG staff and the public about what planning work is underway across the region and where to find more information about studies in the area.

The regional corridor planning web map shows the range of planning studies that are underway across the region, including bike/pedestrian studies, transit studies, corridor studies, and environmental studies, such as the National Environmental Policy Act and planning and environmental linkages. The web map's primary focus is corridor studies on the regional roadway system – transit service, arterial roads, state highways and the federal highway system. The web map also shares key information related to each study’s status, transportation improvement program funding status and links for additional information.

DRCOG staff will regularly update the web map. Contact DRCOG to recommend updates or suggest transportation planning studies not included on the map.
