of interesting note is that several diagrams and figures in the IDOT (IL) Bridge Manual use this bridge as an example. It has always been of interest to me. Other similar types like the Clark Bridge in Alton followed.

According to IDOT files, a contract was let in 2009 for the repainting of the bridge. Included in the big package was the attached diagram that shows the lengths of the various spans of the bridge.

I find it interesting this bridge, barely over 20 years old, is rated as structurally deficient, yet the other bridge, nearly 80 years old, is rated as not deficient. I'm curious to know why this much younger bridge is deficient. Thank you, and I enjoy this website immensely.
