Connecting Detroit and Ann Arbor

This service is temporarily suspended due to the COVID-19 pandemic

D2A2 is a pilot express bus service connecting Detroit and Ann Arbor, MI. The new bus service is an idea created by the Regional Transit Authority of Southeast Michigan (RTA), in partnership with the Ann Arbor Area Transportation Authority (TheRide) and operated by Michigan Flyer.

Statement from RTA Board and Senior Staff

The murders of Ahmaud Arbery, Breonna Taylor, George Floyd, and so many others have been a stark
reminder that our nation’s Black communities are engaged in a daily struggle for justice, equity, and
survival. It is now plainly obvious that awareness of racism is no longer enough, and that it is not the sole responsibility of the Black community to fix this problem. It is incumbent on all of us to speak out, take action, donate, and educate. Most importantly, we must listen, we must elevate voices, we must change.

Detroit to Ann Arbor Express Service

The RTA is in the process of considering how we can safely bring the Detroit to Ann Arbor Express Bus pilot (D2A2) service back online. We don’t have a target date for restarting at this time, but we have begun active conversations with our project partners to determine the most effective approach to restarting the service. Our potential customers are a key part of this conversation. Please contact us here and let us know if you still plan on using the service once it reopens.
