I wonder if there are more bridges like this.
“I wonder if there are more bridges like this.”
That was rhetorical, right?
There were thousands of bridges built about the same time using the same materials, and designed by engineers of the same generation of background and training.
Luckally, not all of them are subject to the same corrosive environment, but some are.
Maybe I'm cynical, but which makes more economic sense for a state: (1) spend state tax dollars to properly maintain a bridge, or (2) spend those state tax dollars on something else; when the bridge fails as a result, let the federal government use other people's tax dollars to rebuild it.
