Great work! I have been wondering about this one for a long time, thanks for sharing these excellent research results!

I was able to confirm that the main Whipple Through Truss span was located at Chicago, Illinois over the now filled in I&M Canal. It was built in 1888 as an original double track structure on that line. This was the only 254'10" Whipple Through Truss in the entire Santa Fe system. In 1934, it was filled in and relocated and reused as an overpass in Shopton (Fort Madison.)

Known as the Shopton Overpass, this bridge was built in 1930 using recycled railroad pieces (according to ATSF bridge records), however no original erection date or location were provided. I have acquired complete 1916 steel bridge records for the ATSF system, so I should be able to find the original location and date of at least the truss span.

I'd assume that it still exists.

Because the comment that refers to it in the past tense is in 07, and the most recent (the one with the side view) is from 2010.

If I can get down to Fort Madison (or out of bed in general) over spring break I'll have to check it out.

Definitely a Whipple truss.

Is it still in existence? A comment on one of the Flickr photos referred to it in the past tense.

I would call it a Whipple Truss.

So, based on the image in the link (even though it isn't a whole shot of the bridge), what type of truss would this likely be?
