This concrete bridge is currently the supporter of the Canadian National (previously Illinois Central Gulf) railroad. It was built over rock creek to allow the Chicago Subdivision line to run south out of Manteno. It shows signs of originally being a wooden trestle bridge, but is now a concrete slab design that was in use in a track chart dated 1955.

This bridge also once carried an Interurban "Street Car" line that ran through to Kankakee on the east side of the Illinois Central main line. That could account for additional bridge width as well.

Vintage imagery shows that the route used to be triple-tracked, so that explains the width of the structure:

Looks wide enough for a road and it looks like the side walls have been built up. Any speculation as to why they went to this extra effort?
