This bridge contains a relatively short through truss main span with five panels, and there is also a single wooden stringer approach span.
The truss main span is configured as follows: Top chord and end post: back-to-back channels with cover plate and battens. Hip verticals: loop-forged eyebars. Other verticals: back-to-back channels with v-lacing on each side. Bottom chord: loop-forged eyebars. Portal bracing: paired angles riveted to lattice webbing. Sway bracing: paired angles riveted together. Lateral bracing: rod. Floor beams: built-up "fishtail" style beams. Railing: Modern Armco guardrails. Deck: wooden deck stringers with asphalt wearing surface. Substructure: Metal caissons (lally columns) pier and concrete abutments.
This bridge appears to have been well maintained with a recent coat of attractive red paint observed and no apparent pack rust, section loss, or even surface rust. Linn County appears to have a good commitment to maintenance and preservation of its historic truss bridges. Hopefully it will continue this commitment in the future, since bridges like this one will continue to give safe and functional use for decades to come if maintained.
