Kind of scary that if one span goes, the whole bridge goes. I wonder how many more of our bridges are like that?

Almost all of them. Bridges often have to use a balancing effect or cantilever or other some such engineering device, such that the thing has to stand as a whole. Look at suspension bridges for example. They can't fail just a little bit.

The Tappan Zee is a scary bridge.
