View of the model of the Columbus Drive Bridge. 
"Eric Bronsky contacted HistoricBridges.org with some interesting information about this bridge. He worked for the Chicago Department of Public Works from 1976-1989. As an architectural modelbuilder, he built several models for Chicago, including the display model of Columbus Drive Bridge. In the era before CAD, physical 3D models were frequently built as a design check. While building this model, he encountered a structural conflict and brought it to the attention of one of the designers. Sure enough, there was an error in the engineering drawings that required modifying the design. This model has not been displayed publicly since around 1990, and it is not known if it still exists. Eric kindly provided the below photo showing the model."

"It is unique in two respects. It is the first bridge in the group to use box girders to span the river instead of trusses. It is also the first to have its trunnions set back from the river to allow pedestrians to walk under it at river level." [ChicagoLoop]
