My brothers used to have one of those hot wheels race tracks that were basically flat pieces of plastic that you jam together. It was flexible enough that you could prop it up on things to make "hills" in the track.

The 35W bridge collapse reminds me of when the track would separate and fall to the floor. How is it that the framework beneath it seems to have collapsed so utterly? I know that some of it is hidden in the water, but doesn't it sort of look like there was nothing beneath the asphalt?
