We're getting reports of some sort of construction crane collapse/malfunction at the site of the future state Public Utilities Commission building at 525 Golden Gate Avenue (near Civic Center behind the state court). Part of Polk Street is now closed to traffic and there's debris lying in the street on Golden Gate. We'll update you as we know more.
