"The two-span steel through truss bridge, which crosses the Rio Chama, is the sole example of this kind of bridge on the Cumbres & Toltec. A Pratt design, the spans were built by the New Jersey Iron & Steel Company. According to Wilson and Glover, the trusses were installed across the Rio Chama in 1924, but were used near Delta, Colorado prior to that date."
Seems to me that this bridge likely wasn’t originally built 1924. It looks like a late 1880s or early 1890s span to me. Without knowing much about the railroad, it appears to be possible that it was relocated to this site.
