In 1962, San Mateo County supervisors voted to leave BART, saying their voters would be paying taxes to carry mainly Santa Clara County residents (presumably along I-280, SR 92, and SR 85). The district-wide tax base was weakened by San Mateo's departure, forcing Marin County to withdraw a month later. Despite the fact that Marin had originally voted in favor of BART participation at the 88% level, its marginal tax base could not adequately absorb its share of BART's projected cost. Another important factor in Marin's withdrawal was an engineering controversy over the feasibility of running trains on the lower deck of the Golden Gate Bridge, an extension forecast as late as three decades after the rest of the BART system.See BART Composite Report, prepared by Parsons Brinkerhof Tutor Bechtel, 1962 The withdrawals of Marin and San Mateo resulted in a downsizing of the original system plans, which would have had lines as far south as Palo Alto and northward past San Rafael. Voters in the three remaining participating counties approved the truncated system, with termini in Fremont, Richmond, Concord, and Daly City, in 1962.
