The closure of the Bay Bridge led BART to have the third-highest daily ridership total in its history last Thursday, agency officials said.
BART trains took a total of 475,015 riders around the Bay Area on Thursday, well above the previous third-highest total of 442,067, which occurred during an emergency closure of the Bay Bridge in October 2009.
Only the days of the San Francisco Giants' World Series victory parades in 2010 and 2012 saw higher ridership numbers in the system, with 522,198 in 2010 and 568,061 last year, agency officials said.
BART spokesman Jim Allison said large crowds were expected on trains throughout the Bay Bridge closure, which began Wednesday night and ended late last night.
The 427,554 trips taken Wednesday on BART trains was the agency's 10th-highest daily total ever.
