San Jose Mayor Matt Mahan speaks at a Diridon Station media event with local business leaders in San Jose, Calif., calling for federal funds to complete the long-promised BART extension, Tuesday, July 9, 2024. A coalition representing hundreds of businesses on Tuesday released a letter sent to U.S.
Phase I of the BART extension brought service into Santa Clara County from Alameda County, with stops in Milpitas and North San Jose opening in 2020. Over the last two decades, Santa Clara County taxpayers have kicked down more than $4.6 billion from local tax measures for the project and the state has contributed another $1.9 billion. The Santa Clara Valley Transportation Authority is designing and building the South Bay extension. BART will operate and maintain the line.
