> But sure, the cost of "one bridge, please" has gone up over time.

Even if you adjust for inflation?

Depends, do we care about TCO? Also, can I pick the set of bridges I compare?

OK, kidding aside: If you deeply care, you can probably mine the Federal Highway Administration's bridge construction database: https://fhwaapps.fhwa.dot.gov/upacsp/tm?transName=MenuSystem...

I don't think the question is answerable in a meaningful way. Bridges are one-off projects with long life spans, comparing cost over time requires a lot of squinting just so.
