Here is a link to a draft by the Illinois Dept of Transportation on the bridges and culverts on the Chicago-St. Louis high speed line.
It has many pages on the history of the line then a description of the bridges. Those with photos are marked, but the pictures themselves are numbered and you would have to find what bridge it is up in the description list.

Some really cool looking bridges though.
