San Francisco sister-site of or LAist, SFist, is reporting that all Southbound lanes of the Golden Gate Bridge are closed, and most northbound lanes were "moving very slowly" due to a motorcycle accident involving multiple cars on the Golden Gate Bridge this afternoon. Traffic was backed up to 19th Avenue according to CBS 5 (where Allen Martin had the unmitigated gall to interrupt The People's Court to tell us!)
