Living here in Chicago it's neat to see the vestiges of this still around - like 'vaulted sidewalks', where the current sidewalk sits over 5 feet of air, and then the old sidewalk is down below:

Pictures or it isn't true!

Here's my grandmother's old neighborhood in the near southwest part of the city (Pilsen):

You can see where the sidewalks enter on the second floor of these flats and the original ground level entrance is now below street level.

We had lots of fun goofing around in the "cave" down on the first floor.

It's very bizarre seeing a street view from a block away from where I live on HN.

Sorry, that's where GMaps put the center of Pilsen. I can update the link if you want... =)

(ObGmapsWeirdThing: My wife and kids were outside on the driveway when the google cameras went by. Now I can see them all the time, staring back at me with their blurred faces...)

It is random. I lived about two blocks away on 18th place.

Hello, half-mile away neighbor.

Here's a thread with a bunch of pictures of Chicago excavations that have exposed vaulted sidewalks http://forum.skyscraperpage.com/showthread.php?t=143407

These are the signs by my wife's office - it's really hard to visualize but at points in the sidewalk there are grates that you can see through down to the old sidewalk below
