The Skyway, which crosses the Calumet River and surrounding industrial area to connect southern Chicago to northwestern Indiana, has a nice curve to it. The road itself is just another bridge, pretty standard stuff, but one big reason the Calumet River tours were so much fun for me was that I really like seeing what it takes to build something like that. I wonder whether there’s an engineering reason the bridge has that sweep to it, or a traffic planning reason, or some other situation.
