"Since the start of the COVID-19 pandemic, we've been focused on providing a safe and healthy public transit environment for our operators and riders like you," the CTA said in a statement Friday. "Allowing people to board buses through the rear door was an initial action in the immediate weeks following the start of the COVID-19 crisis, while additional safety measures were still in the process of being implemented on our system."
The change is made in partnership with the Amalgamated Transit Union Local 241, the CTA's bus operators union.
