Built in 1942, this structure is Oklahoma's only through Warren truss with curved top chords. The length of this through span is 250 feet, the longest span in a highway bridge, but not the longest span (that distinction goes to the Wanette-Byars, with its three lengths of 265 feet each).
Below, an overview of this large structure.
Above, a side view. Note that the approach spans are not stringer spans, they are riveted deck girder spans, much like you might see on a railroad bridge.
Above, a close view of the Warren truss span. We plan on returning on a better day to get a good side view of this span. Note the massive, tapered concrete piers holding this span.
Below, a close-up of the construction of the approach spans. Normally we do not give so much attention to approaches, but these are different than most and quite substantial.
Above, David serves as a scale. You can also see more clearly the construction of these riveted spans.
Above and below, details of the light/electric poles. These appear to be original.
