This is an abandoned section of the original Route 66 in McCook, Illinois, a small, industrial suburb of Chicago. The highway was condemned and closed to traffic in the mid-90s when quarrying operations (blasting, etc) hundreds of feet down on either side destabilised the roadway, causing it to crack, sink and partially collapse. It's fenced off, but that doesn't stop anyone from *walking* there, and that's a totally weird, surreal, post-apocalyptic feeling, a chilling look at a world without humans. Check out the Sears Tower in the background.
