    About the Flatiron Flyer

    The Flatiron Flyer (FF4, RTD route FF4) is a bus rapid transit line with 15 stops between Boulder Junction at Depot Square Station Gate B3 and Civic Center.

    Times with the live mark come from each bus's GPS and RTD's real-time predictions. Times marked "Not tracked" are scheduled trips with no bus reporting. All other times are from RTD's published schedule (feed Sep26-37329-18-19-20261030-143459).

    What are timepoints?

    Timepoints are stops where the bus is scheduled to wait if it's running early; times at the stops between them are estimates. On long routes, the diagram shows timepoints, transfer stops and stops with a bus nearby, and groups the stops in between.
