i'll just leave my 'ol pic of cleveland's deco guardians of transportation right here
http://en.wikipedia.org/wiki/Hope_Memorial_Bridge
^ if you can believe it, al porter aka cleveland's robert moses, a guy who canceled cleeveland's subway plan after it was passed by the voters, had this to say about the guardians when he wanted to widen the bridge: "Those columns are monstrosities and should be torn down and forgotten. There is nothing particularly historic about any one of them. We're not running a May Show here (may show=annual art show)."
