South Bay Rapid construction began in March 2016. New Rapid transit service is expected to begin in late 2018/early 2019.

The SANDAG Board of Directors certified the South Bay Rapid project’s environmental impact report on July 26, 2013.


South Bay Rapid is funded through TransNet, a regional voter-approved half-cent sales tax to accelerate construction of high-priority transportation projects. The overall project budget for the TransNet Early Action Program phase of the project is approximately $113 million. This budget includes costs for capital improvements, property acquisition, and support costs for design engineering and construction.  An additional $15 million is budgeted for the procurement of new Rapid vehicles.
