This bridge was the site of the first metal bridge, a Whipple through truss, on the Illinois Central, built 1860. An 1897 through truss replaced it. Based on imagery it looks like a 2 span pony truss is there now. The bridge must date to after 1921 since the through truss still stood in 1921. http://www.archive.org/stream/illinoiscentrale21illi#page/n1...
