I also like the San Antonio lenticular bridges because they are among the only historic bridges in all of North America that use more than one paint color on the trusses. This eye-catching technique is more common in England.
The lower chord eyebars are prevalent in the first 2 panels but are otherwise obscured by the walkways.
Definitely one of the most beautifully ornate parabolic spans remaining!
The lower chords are lightweight and are not visible in the first photograph. Photograps 2 and 3 reveal them, but in some photographs this bridge just looks like a Parker with vertical endposts.
Beautiful bridge. Details are unusual. However, I don't see the Lenticular elements. Looks more like a Parker truss to me.
