Tri Delta Transit wants to bring information to you from a partner.

This summer, Contra Costa Transportation Authority - CCTA partnered with BORP Adaptive Sports and Recreation and Independent Living Resources of Solano and Contra Costa County to host three free adaptive cycling pop-up events across Contra Costa County. The events will give residents with disabilities the chance to try hand cycles, therapeutic trikes, and other adaptive bikes close to home for health and happiness.

CCTA asks that you take a short survey to help them with this program. Thank you for your time.
