Newscopy: "Bay Bridge and Key System workmen survey damage done to the span's lower deck today when the tip of a crane boom rammed through the superstructure and caught there. Note heavy steel beam projecting diagonally above Key System tracks. Key System bridge train service was halted by the accident... A giant crane, atop a barge, slammed against the lower deck of the San Francisco-Oakland Bay Bridge shortly before noon today, temporarily halting all Key System bridge train service. It was more than an hour before the monster crane could be dislodged from the bridge superstructure."
