Description 

This bridge is the only one of the St. Charles Air Line bridges to have decorative elements. That is possibly due to the higher-class status of Michigan Avenue. The bents are particularly decorated and attractive.

CN - Michigan Avenue Bridge
Posted April 13, 2019, by Roger Deschner (rogerdeschner [at] gmail [dot] com)

All of the 120 year old bridges of the St. Charles Air Line are scheduled for replacement in 2019, including this one. But this is the one that will be the most painful loss, due to its highly attractive decorative elements. It's also in relatively good condition, compared to the others, and could be fixed rather than replaced.
