The bridge you're trying to remember is probably the Golden Gate bridge. There's a documentary about suicides and attempts from the that bridge called "The Bridge", which for me was riveting:
That particular police officer they were interviewing was a pretty old guy, who spent many decades working on that bridge and so have seen it all.
It was a good 5 years ago, maybe even more, so my memory is a bit hazy.
You think they’re going to show people who survived a suicide attempt saying, “dang, really upset I didn’t die.”?
