PANYNJ: "Today, the Australian half, now paired with another blade, remains on permanent public display at the Stanton Library in North Sydney. The Bayonne half? It vanished, never to be seen again. The mystery of how it went missing and where it might possibly be continues to bedevil bridge buffs and Port Authority historians alike. Its loss wasn’t discovered until 1981, when the Port Authority — preparing to celebrate the 50th anniversary of the Bayonne Bridge — wanted to bring the artifact out of retirement. It was nowhere to be found."
