Description 

The Lookingglass Creek Bridge outside of Winston, Oregon is an oddity of bridge design. The bridge consists of multiple styles of steel superstructure design.

The main span consists of 80-foot long castellated steel girders. The main span is then flanked on each end by 48-foot long compact deck truss units. The trusses consist of two linear units comprised of three riveted truss lines. There are two truss unit lines under each side of each of the flanking spans. The end spans consists of welded plate girders at the south end and rolled steel girders at the north end.

The bridge is owned by Douglas County, which features a collection of some of the most unique steel bridges on the west coast.

The bridge was constructed in 1959 by West Coast Steel Works of Portland, Oregon.

Sounds like how there's a story about Ames, Iowa's lost Dinkey Bridge being used to transfer nuclear material made at the Ames Lab clandestinely to the CNW: https://bridgehunter.com/ia/story/dinkey/

Can't confirm or deny the stories, but they sure are fun.

The stories state that these trusses along with many of the other odd ball steel structures in Douglas County come from the Kaiser Ship Yards in Portland-Vancouver and were either parts from Liberty Ships or were part of the structures used to build Liberty Ships.

I can't confirm or debunk these stories, but they are good stories.

Mike,

I take it there is a story here... known or unknown? The trusses appear to be salvaged material based on the huge number of empty rivet holes.
