The trusses are from a bridge built in 1883. The trusses were moved here in 1921. The bridge was abandoned in 1997. [ArchivedBidgeHunter]
I thought I saw pins in the bottom cord in the view above. But I see rivets in this photo. HistoricBridges and John Marvig describe this bridge as "an extremely old surviving example of a rivet-connected truss bridge."

"This bridge was built 1883 at Geneva, IL as Spans A&D of Bridge #66; these spans were moved here in 1921. I would assume the builder is Alden & Lassig, but I cannot confirm at this time. From what we have figured out, the original Geneva bridge had three truss lines on four spans (two long spans and two short spans). The outer truss lines were the "light" lines, the inner truss line between the two tracks was the "heavy" line. It seems that the two short/heavy lines were sent to Spring Creek, and the two heavy/long lines were sent to Lick Creek, along with the four light/short and four light/long truss lines. These were double trussed to make them stronger. The Lick Creek bridge has three spans, and the north and south spans are the "light" trusses, which were double trussed. The middle span is the "heavy" truss, which explains why it uses a conventional layout. I am still trying to figure out if the "heavy" trusses are original to the 1883 bridge, or were added later."

We can more clearly see the use of rivets in this photo.
