Flatiron Flyer - Bus Rapid Transit
The U.S. 36 project is a Colorado Department of Transportation-led project that brought 18 miles of Bus Rapid Transit (BRT) service between Downtown Denver and Boulder along U.S. 36 as part of the FasTracks program.
The Flatiron Flyer is the official name of RTD's new Bus Rapid Transit service that was added as part of the FasTracks program approved by voters in 2004. The Flatiron Flyer service, combined with the U.S. 36 highway and parking improvements, is the result of years of work and collaboration between RTD and CDOT.
The Flatiron Flyer is an efficient, quick and environmentally friendly commute option connecting Denver, Westminster, Broomfield, Boulder and everywhere in-between.
