Well, almost.
I was playing around with the Google Earth plug-in for Google's online maps, which lets you pan around and fly through 3-D buildings and topographic features, when I noticed they didn't include a 3-D model of the elevated freeway structure. Comparing the resulting freeway-less images with the real-life Street View is like looking at before and after pictures of a future in which the skyway has been torn down. One I hope we'll someday see.

Play around with it for yourself, it's refreshing to see what an improvement all that blue sky can make. More pics after the jump.
