The Denver Regional Council of Governments implements the current regional transportation plan through the Transportation Improvement Program. The program identifies all current federal- and state-funded transportation projects to be completed in the Denver region over a four-year period. Demonstrating DRCOG’s commitment to collaboration, its local governments decide on a process and criteria for including projects in the Transportation Improvement Program and awarding DRCOG-controlled federal and state funds, which allows the region to set and agree upon its transportation priorities. All program projects must meet current air quality standards.

Policy development

In early 2022, DRCOG adopted the Policies for Transportation Improvement Program Development. The latest version of the Transportation Improvement Program policy document will supersede any previous versions and will be used to guide the calls for projects associated with the development of the fiscal years 2024-2027 Transportation Improvement Program.

Subregional forums

For all project allocation activities, a subregional forum is responsible for submitting projects, programs or studies for consideration by the DRCOG Board of Directors. Subregions are geographically defined as a county and all the municipalities within. Every member government within each county is invited to participate in their subregional forum. The Colorado Department of Transportation and the Regional Transportation District are invited to participate as non-voting members. Other eligible stakeholders may be invited at the discretion of each subregional forum.

The eight counties in the Denver region hold subregional forums; Adams County, Arapahoe County, Boulder County, City and County of Broomfield, City and County of Denver, Douglas County, Jefferson County and Weld County (southwest portion). Links to individual subregional forum meeting agendas and other materials may be found on the individual county websites, in addition to being accessible through the DRCOG calendar

Regional set-asides

In addition to the main regional and subregional calls for projects, DRCOG also develops and maintains a group of regional set-aside programs, each having its own funding amount and call for projects. View each of the individual set-asides.

Annual list of federally obligated projects

The current report includes all projects in the Denver region that received federal obligation in 2023 (October 1, 2022, through September 30, 2023). Obligated projects are those that have been approved by the federal government for reimbursement.

TRIPS database

DRCOG staff maintain TRIPS, an online database, for projects in the Transportation Improvement Program.

Dual model process

DRCOG's dual model process provides opportunities for subregions to fund local priority projects in addition to regional priority projects with a continued focus on Metro Vision and the Regional Transportation Plan.

2024-2027 Transportation Improvement Program

The Transportation Improvement Program for fiscal years 2024-2027 identifies federal and state-funded transportation projects to be implemented in the Denver region. It was programmed through two calls for projects, a regional and subregional share. 

The projects in the Transportation Improvement Program are regularly updated through administrative modification and amendments. These changes are reflected in the most recent version of the project descriptions. Review specific amendments and administrative modifications:
