Transforming transportation in Colorado
FasTracks is RTD's voter-approved transit expansion program -- the largest in the nation -- transforming transportation through the Denver metro area. When complete, FasTracks will create better access and more transit options across all of our communities. That's more rail, improved bus service, more parking, and improved roadways and bridges for people on the go. Now that's progress.
122 miles of new rail service
18 miles of bus rapid transit
57 new stations
31 new Park-n-Rides
21,000 new parking spaces
