Geoff, your postcard is of the predecessor bridge to this. Good find on the image of the steel truss. Given the pinned connections, it was almost definitely relocated to the spot by the Western Pacific, which controlled the SN.
I found it in the waybackmachine, so the link should work again.
And that's definitely the predecessor bridge built by the Northern Electric Railway, which is shown here covered: https://books.google.com/books?id=mCtLAQAAMAAJ&pg=PA738&dq=n...
1906 postcard Feather RIVER. Could this be interurban?
