Significance: The Crooked River Bridge is a rare example of a Double Intersection Warren Through Truss (the main span), with a secondary span comprised of a Warren Pony Truss with Polygonal Upper Chords. Both spans are of riveted steel construction. The through truss main span was relocated to its current site in the 1930's, and attached to the pony truss span to accommodate the width of the Crooked River at this crossing. The two-span structure has an overall length of 206 feet, and overall width of 18.5 feet. The vertical clearance of the through truss span is 16 feet. The Warren double-intersection truss is one of two remaining of tis type in the State of Oregon.
