This is horrifying to even imagine being a person on the bridge. It was only a blink. I feel for their families.
Speaking of horrifying stuff involving bridges. San Francisco recently conpleted the suicide net which covers nearly all of the sides of the golden gate bridge. I saw it last year.

I thought to myself how stupid that is because of the fact that if someone is determined, they can easily just continue over the net. I later realized that if it makes even 1 person stop themselves from jumping then it is worth it. There are a lot of people who have jumped from this bridge.
