The Red Bridge
Posted May 18, 2017, by Michael Quiet (mquiet [at] gmail [dot] com)

Very interesting find here...it indeed looks like a bridge built of the Douglas patent. I have seen occasional mention of Corrugated Metal Co. building a few spans based on the Elliptical truss patent, but these bridges were quite crude and did not hold up well (no doubt owing to some of the design faults visible in the patent drawings, note that the diagonals are sloping in the wrong direction!). It was only when the Yale educated engineer Charles Jarvis was brought in that the design was refined (adding counters to each panel and smoothing out the upper and lower chords) to create the lenticular truss we know.

I'd opt for referring to it as an Elliptical Truss though, just to highlight the difference between this bridge and the extant lenticular trusses that remain today.
