Great posts. I walked the Ogden viaduct over Goose Island in September 1991 and February 1992 (not long before demolition). Scans from the 1991 trip are posted on this site, the 1992 scans are in purgatory somewhere in suburban Maryland. A fun structure to climb on and around, but a bit scary toward the end due to possibilities of crime and cement chunks falling off of it. The bas-reliefs on the bridges were treasures.
