BNSF - Skunk River Bridge
Posted October 26, 2016, by John Marvig

Nathan,

I have yet to upload my photos. There was an 1899 plate on the bridge. It almost looked to me like there were several lines of chords on the trusses, and it was originally built massively. In addition, one of the trusses is a different design, and has riveted connections.

Looks to me like this bridge's pin-connected spans were enhanced by adding additional pin-connected truss lines to the bridge. I count four total bottom chords, so two are original and two are added. The approach spans that are riveted connections likely date to this project. Photos show scraps of riveted metal and other potential leftovers from this project. What is unclear to me, did this all occur in 1905, and if so, the pin-connected truss spans may be older... or were the extra pin connected truss lines and other aforementioned enhancements added after 1905? Any use of pin-connected design even as part of rehab/retrofit projects would be somewhat unusual after 1905.

This was the 2nd (or possibly 3rd) bridge for the CBQ's crossing of the Skunk at this location. The original crossing was about 1/4 mile downstream from this one. Crumbles of the original piers can be seen on the Google maps image just downstream.
