	Kansas City all over again. I guess it's been a few years. When aesthetics dictate design . . .

	A tragedy, to be sure, but I sure wish we could get some substantive reporting here. Notice that the transporters are moving the structure from well inboard of the ends. I wonder if it was "tested" at the construction site by removing all but the end supports? Who says that the structure is self supporting without the stay cables? It appears to be a cable-stayed bridge, after all. Call me old fashioned, but I like to see the steel that supports everything--why cover it with concrete and bear the burden of extra mass. I have read numerous articles about the unseen deterioration of steel that is embedded in concrete. As one of my mentors said; "the art of engineering is the art of materials".
