I'm not sure which bridge Molly went down on - on Halsted there are 3-4 bridges alone, but I highly suspect one of them. Josh - was it the one at Chicago or the one at Division?
The bridge I went down on, I went back later to take a photo of but didn't see any offending cracks - granted it was a month or so later too, so maybe they fixed it, I don't know. I was actually sort of hoping/scared that I might have some flashback of what happened since I remember nothing 20 feet from where I went down and until I came to in the hospital.
Bridges are everywhere in Chicago. Ask Judah - when he was in town, he was shocked. Bridge after bridge after bridge. Of course, it's all downtown in the business district though.
