Thanks for Hopping on Board!

During the month of August 2022, public transit agencies around the state of Colorado joined together to take part in 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 use of public transit. Transit riders benefited from the program as many transit agencies, including RTD, allowed riders to take transit for free August 1-31, during Colorado’s high ozone season.

We hope you enjoyed taking advantage of Zero Fare August to try transit to get to work, school, a Doctor’s appointment, or a weekend exploring Colorado.

Some of our transit riding friends participated throughout the state by signing up and tracking their rides on the web-based application that tracked how many rides they completed, CO2 emissions saved, and gas money saved in August! Prizes have been awarded. Stay tuned for next year by signing up for CASTA eNewsletter in the footer of this webpage so you don’t miss out.
