"One of these arch bridges actually has a structure built under it to catch falling deck ... see that structure underneath it, they actually built that to catch falling concrete." ... "They built a bridge under the bridge..."
They've since repaired this one.

On boring overpasses they stick boards across the bottom flanges of the I-beams. On fancier types of bridges they have to come up with more elaborate ways to catch stuff.
