| One of the few bridges dedicated in 1947 (posthumously) to its designer, this cantilever truss exhibits an array of architectural and decorative features. In addition to its distinction as one of the most impressive of Oregons bridges, it was the longest structure on Oregons highway system when constructed: 5,305 feet. The 1,709 foot through truss has a main span of 793 feet and is flanked by thirteen open-spandrel, rib-type reinforced concrete deck arches. To ease design conflict between the steel truss and the arch spans, the cantilever was constructed with curved upper and lower chords. David Plowden in Bridges: The Spans of North America (1974) states: Few later bridges of its type have been as outstanding. (Photo: Dennis Wolverton)
