Here's one way to get from an eighth-story office to the nearest Post Office: Jump out the window, then walk to the nearest Post Office. If you were going to do that, you'd want a hell of a cushion to land on, right? My point is, destroying Lake Shore Drive is a huge freaking leap, and unless the people who live and work in Chicago have something to land on the moment they need it, the immediate dislocation will cost more than Chicagoans can pay. These kinds of massive multi-phase synchronized plans are something nobody is really good at yet, with NASA and the ESA probably coming closest. I don't really want to bet Chicago on one of them coming together just right.
