CWRR - Yakima River Bridge
Posted January 29, 2020, by John Marvig (marvigj27 [at] gmail [dot] com)

Added some information on this bridge from NP bridge records. It appears all three spans were moved here after the 1906 flood, but before the 1960s flood.

In trying to find other spans, I found one more nearby (https://bridgehunter.com/wa/king/snoqualmie-trail/) that is the same dimensions, year and builder as the two Lassig spans on this bridge. In addition, the relocation date is the same. I believe the two spans on this bridge and that one span in King County were probably on the same bridge. The King County bridge reportedly came from the 7th Crossing of the Yellowstone River near Billings, which according to my records had 3-160' trusses and was rebuilt 1923.

Builder's plate in photo 2 has 1891. There have probably been repairs to substructure, perhaps even replacement spans, at later times.

In my research I got two contradicting dates of when the bridge was destroyed First date is 1906 according to Yakima Museum. The other is 1964 based on the Whitnall family. They claim that their dad, Jack Whitnall was working for Boise Cascade as promo-man and took this picture at the same time.

I would like to verify this. Any help would be apppreciated

BTW I have family permission to post this picture.
