West Face
The bridge was originally built by the Chicago, St. Paul and Fond du Lac Railroad, later acquired by the Chicago & Northwestern. It appears that the bridge was widened in 1897 to accomodate a second track.

South Street Arch
The 7th Street Improvement Arches in St. Paul, MN, also uses this helicoidal arch design. This bridge has two spans rather than one.

I found this gem in Woodstock, Illinois while I was looking for something else. Note the heliocoidal arch construction - I've never seen anything like this before.
