CU faculty and staff can enjoy RTD services throughout Colorado without breaking the bank by using your Buff OneCard

RTD offers routes along the I-25 corridor throughout Denver and Boulder, offering Coloradoans the opportunity to alleviate car pollution and help the environment. In this spirit, CU wants to encourage students and staff to take advantage of Colorado’s robust public transportation by offering Eco Pass access using your Buff OneCard.

The passes provide access to all Local, Limited, Express and Regional bus service, in all fare zones, including the SkyRide bus service to DIA. 


Full-time CU Boulder faculty and staff, CU System Administration staff, part-time continuing employees and retirees who have retired from and returned to work on the CU Boulder campus are eligible. Employee eligibility and bus pass options are listed on the Parking and Transportation bus webpage.

Note: System Administration employees who currently have Buff OneCard without the RFID logo will need to contact the Buff OneCard office to receive a new card for EcoPass use. Full details on how to replace lost or stolen cards are on the Buff OneCard website.
