South Bay Rapid began a limited service route in September 2018 between the East Palomar Station at Interstate 805 (I-805) in Chula Vista and Downtown San Diego. In early 2019, South Bay Rapid service will expand to full service and operate 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.
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.
