BART is operated by the San Francisco Bay Area Rapid Transit District which formed in 1957. The initial system opened in stages from 1972 to 1974. The system has been extended several times, most recently in 2020, when Milpitas and Berryessa/North San José stations opened as part of the under construction Silicon Valley BART extension in partnership with the Santa Clara Valley Transportation Authority (VTA).[10]
