Due to Caltrans closing the Bay Bridge in both directions over the upcoming Labor Day weekend for earthquake retrofitting, BART will be running hourly overnight service to 14 stations during the wee hours of Friday, September 4 through the early morning hours of Labor Day on Monday, September 7. Participating San Francisco stations will be the 24th Street Mission, Embarcadero, and Powell Street stations, as well as the San Francisco International Airport station. We've never experienced a late-night holiday BART ride but can imagine they'd be pretty rowdy, not to mention the tragic Oscar Grant shooting that occurred this past New Year's Eve. Stay safe and keep your wits about you, BART passengers. [Via Eyes on Blogs, SFBART]
