Glory
"Out with the old, in with the new" is the motto you live by. You tear down infrastructure that's dangerous, outmoded, or ugly, in favor of the bright and the shiny—and you do it with style.
As we've mentioned, it's all one big cycle; your demolitions lead to new construction projects, which lead to economic growth, which leads to further building of things which will eventually be demolished. And thus the glorious cycle, in which you play a major role, begins anew.
When you go to town on an old overpass, you're not just making thousands of people's commutes safer. You're creating jobs. As a public-safety-oriented job creator—and somebody who gets to smash lots of stuff—you'll have plenty to feel good about in this career.
