On January 27, 2019, South Bay Rapid launched full service along a 26-mile route between the Otay Mesa Transit Center and Downtown San Diego.

The SANDAG Board of Directors certified the South Bay Rapid project’s environmental impact report on July 26, 2013. South Bay Rapid construction began in March 2016 and is expected to be completed in late 2019.


South Bay Rapid was funded through a combination of local and state funding, including $128 million in TransNet and $11 million in state Cap-and-Trade funds.
