Tri Delta Transit heard what the community had to say.
System changes are effective September 12, 2022.

In October 2020, Tri Delta Transit sought community input to improve transportation service in eastern Contra Costa County. Tri Delta Transit worked with a consultant, Advanced Mobility Group (AMG), to conduct vast community outreach called Transform Tri Delta Transit with the goal of learning more about what eastern Contra Costa communities want and how they envision the future of Tri Delta Transit’s service.

In fall 2021, Transform Tri Delta Transit launched a follow-up community outreach campaign with a survey about proposed changes that were based on the 2020 Transform survey results. The survey focused on which of the suggested improvements were the greatest value to residents and transit riders.
