A big ol' sinkhole broke out today on First Street between Mission and Howard due to a water main rupture, resulting in the closure of a major artery out of SF and onto the Bay Bridge. Traffic around the area is backed up all sorts of bad. Sorry, dear East Bayers. But look on the bright side: you get to stay in the city of San Francisco that much longer. Yay, you!
Anyway, due to the street depression, that part of First Street won't reopen until tomorrow morning. Read more about it here.
