You will get a different bridge. With very different technology. Same as "I can't repair my grandfather clock cheaply".
In general, there are several things that are true for bridges that aren't true for most technology:
* Technology has massively improved, but most people are not realizing that. (E.g. the Bay Bridge cost significantly more than the previous version, but that's because we'd like to not fall down again in the next earthquake)
* We still have little idea how to reason about the cost of bridges in general. (Seriously. It's an active research topic)
* It's a tiny market, with the major vendors forming an oligopoly
* It's infrastructure, not a standard good
* The buy side is almost exclusively governments.
All of these mean expensive goods that are completely non-repeatable. You can't build the same bridge again. And on top of that, in a distorted market.
But sure, the cost of "one bridge, please" has gone up over time.
