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.
