Non-RT routes serving Sacramento
Although these routes were once part of RT's lineup, these agencies continue to service Sacramento using the assigned route numbers. The RT system originally excluded service to Sacramento International Airport, which was exclusively served by Yolobus until January 2020 when RT added express service between downtown Sacramento and the airport; Yolobus continues to serve the airport with local service. Service in Elk Grove that was formerly operated by RT is operated by e-tran, which reverted to RT in June 2019. This list also include other transit agencies that coordinate their services and fares with RT.
