Description 

The Chicago & Illinois Western (C&IW) Railway Bridge is a rare-surviving example of a patented bridge design by Theodor Rall. The Rall type was one of the designs used by the railroads in the early twentieth century, and is significant for combining the bascule bridge technologies of both rolling and trunnion motion.
