RTD Zero Fare
2023 Zero Air for Better Air
During July and August 2023, RTD offered zero fares across its system as part of the Zero Fare for Better Air initiative. This collaborative, statewide initiative, made possible by Colorado Senate Bill 22-180, in partnership with the Colorado Energy Office, was designed to reduce ground-level ozone by increasing the use of public transit. Fares were “Zero” (in effect, free) on RTD from July 1st to August 31st, during Colorado’s high ozone season.
