Mapping the invisible: the great Chicago map currently in development

Chicago Magazines’s Whet Moser on the undertaking to produce a 3D map of Chicago’s underground spaghetti of pipes, tunnels, and cables:

Underneath that [ordered street] grid, though, is the chaos of the underworld: gas, electricity, water. And it can be dangerous. The most famous example is the Chicago flood of 1992, when miscommunication over the location of an abandoned freight tunnel, among many other things, allowed pilings to be driven into the ground next to it, causing the tunnel to fail and flood much of the Loop.

Man, I hope this project is completed. I would love to pore over a map of Chicago’s (and eventually other cities’) underground, including, of course, the Pedway.
