This certainly would be a lightweight bridge. Iíve found that thereís really no rhyme or reason to where bridges were relocated to, mostly just based on what was available at that time. If this route was originally constructed in 1888, it would seem to be a fairly light truss for that time period, especially compared to similar structures.

There may be a nearby river crossing that got a wider bridge when the line was double-tracked, similar to what seems to have happened at Sibley on the same line.

ATSF Bridge Records from 1937 give a build date of 1910 and a strengthening date of the floor of 1927. Given other ATSF overpasses, I wouldn't be surprised if this one was also a reused railroad span.
