Raising of Chicago
On a related note for anyone who has walked around both Manhattan and downtown Chicago...Ever notice how downtown Chicago has much less noise of honking cars than downtown New York City?  A friend pointed out it's because of Chicago's lower-level streets[0] that a lot of service vehicles use for loading/unloading.  That's in contrast to Manhattan where everybody has to share the same street level.  E.g. a brown UPS truck that stops for a mere 20 seconds is enough for the yellow cab driver that's stuck behind him to smash on the horn with impatience.[0] https://en.wikipedia.org/wiki/Multilevel_streets_in_Chicago
