On average, a person jumps to his or her death from it every two weeks, more than 1,500 to date. And they are the ones who are known about. Others are thought to have taken the final leap only to be washed out into the ocean, their bodies never to be found, or recovered so far from the bridge that they cannot be classified as jumpers. Many more consider jumping and then think better of it. It is rare for a week to pass without an incident of some kind, a “10-31” in police parlance.
