A big crash involving a turned-over car and at least four other vehicles in the middle of the Golden Gate Bridge has put traffic at a near stand-still in both directions, with only one lane open going either direction (all the lanes were closed until just a few minutes ago). Only minor injuries reported in the accident but clean-up is ongoing and drivers are being advised to take the Bay Bridge and Richmond Bridge to get to Marin if at all possible. UPDATE: All lanes have been re-opened. Watch that lack of center divide, people. And also, slow down on the S-curve (on the other bridge)!
