Welcome to South Bay Connect, a key project identified within numerous local, regional and statewide studies as one of several transportation improvement projects that will improve the Northern California Megaregion rail transportation network, including freight and passenger rail safety and efficiency. As the only public transit service that directly connects the Greater Sacramento region to the Bay Area and Silicon Valley, Capitol Corridor serves as the backbone of the Megaregional transit system, providing essential access and additional travel option to driving on the congested interstates of 80, 680, and 880.

South Bay Connect proposes to relocate Capitol Corridor passenger rail service between Oakland and San Jose to unlock existing rail challenges within the corridor. This relocation was listed within Capitol Corridor Joint Powers Authority’s (CCJPA’s) 2014 Vision Plan Update and 2016 Vision Implementation Plan, as well as the 2018 California State Rail Plan and Plan Bay Area 2040. These rail improvements are also consistent with the Alameda County Transportation Commission (Alameda CTC) 2016 Goods Movement Plan, Alameda CTC’s Countywide Transit Plan and 2018 Rail Safety Enhancement Program, the 2017 Dumbarton Transportation Corridor Study, and Dumbarton Forward Design Alternatives Assessment.

The collective plans establish a clear roadmap for Capitol Corridor that identifies service improvements to be implemented over time.

Population growth within the Northern California Megaregion is not expected to slow down, and providing a seamless, connected transportation network that links housing to jobs is critical. As one of several transportation projects within the Northern California Megaregion, South Bay Connect will lay the foundation for improved rail operations and ensure that Capitol Corridor has the ability to increase capacity when that need arises.
