Nor of any other material. Between the insanely shallow truss depth at the right end of it, and the "can't tell compression from tension" decision to slant all the diagonal members in the same direction - that bridge is a poster child for "I Flunked Engineering 201".

I almost feel like intuition tells you that. It literally looks like it can fold down flat. A regular truss bridge looks like a honeycomb, straining, but balanced.

It just looks so wrong that the cross members don't switch direction in the middle. I can't even look at that bridge without getting creeped out.

that's a pretty political spin. if i remember correctly the bridge in florida was entirely feasible but they got the pre-tensioning and assembly wrong.

The NTSB found that it was actually that the 11/12 node region was too weak as designed, an error that wasn't caught by the reviewer.
