About the TMA

Transportation continues to be the lifeblood connecting businesses through Denver South. Our role as the Denver South Transportation Management Association (DSTMA) is to continue driving the economy forward.

The DSTMA supports the Regional Transportation District’s (RTD) FasTracks projects, specifically the E, F, and R lines that serve the Denver South Region. We embrace Transit-Oriented Development (TOD), while also promoting alternate and environmentally-sound transit choices, including carpooling and telecommuting.

The DSTMA, is a partnership of public and private entities in the South I-25 Urban Corridor working to promote relationships between the partners for the purpose of identifying and developing transportation solutions to enhance mobility, drive economic development and further position Denver South in the  I-25 Corridor.

The TMA’s priority is to improve mobility and maximize interchange capacity and transit ridership to foster growth of employment and the tax based within the corridor.

The TMA is a coalition of local governments; Arapahoe County, Douglas County, City of Greenwood Village, City of Centennial, City of Denver, City of Lone Tree; the Centennial Airport, the Southeast Public Improvement Metropolitan District (SPIMD) and the business community represented by the Denver South EDP who joined together to help solve the Corridor’s congestion problems and to promote economic development in the area.
