FasTracks is Creating Connections
FasTracks is RTD's voter-approved transit expansion program -- the largest in the nation -- transforming transportation through the Denver metro area. Since 2004, we’ve completed the W Line, the Free MetroRide and Union Station. In January 2016, we launched the Flatiron Flyer Bus Rapid Transit service, in April 2016 we opened the University of Colorado A Line rail service between Union Station and Denver International Airport. In July, 2016, we opened the B Line to Westminster. In February 2017, we opened the R Line through Aurora, and soon, we will be opening the G Line – all part of the FasTracks program.
Through the FasTracks program we’re building more rail, improved bus service, more parking, and improved roadways and bridges for people on the go. Now that's progress.

Quality of Life Study
The Quality of Life (QoL) Study is RTD's data-driven evaluation of progress toward meeting the FasTracks Program goals. The QoL Study focuses on the “quality of life” in the context of those areas most affected by transit improvements and those specifically addressed in the FasTracks Plan: mobility, environment, economic activity, development, and land use.
Transit-Oriented Development Projects
Development at and around the system's transit stations is an exciting element of the FasTracks program. As the Denver region's public transit agency, RTD plays an important role in the implementation of Transit-Oriented Development (TOD). TOD is characterized by a pedestrian-oriented environment that allows people to live, work, shop and play in places accessible by transit.
