This bridge has been replaced and opened on October 15th. I'll try to post some new pictures next time I visit home. Here's some pictures from the demolition, as well as a link to a local news story showing Governor Quinn visiting the bridge.

Yup....It's a WIBCo span. Portal embellishments are very much like the Laughery Creek Bridge with the addition of finials.

This pre-1900 photo from an IDOT report shows the previous bridge, a six span pin-connected Whipple through truss. It looks like the work of Wrought Iron Bridge Company.
