we did 2 bridges with carbon fiber wraps back when I was in Atlanta (Cobb County) supposedly we were supposed to get 10 more years out of them, but the cost was still around $100K for each bridge..
If you want to look at some that have been done the bridge I remember was John Ward Road Bridge (somewhere there is a video of me explaining carbon fiber wraps to the public)
I think you have to find which municipalities around the country are open to trying new technologies (although we did this back in 2009) from what I can tell here in Colorado everyone including the state just waits until the bridge is about to collapse before doing any maintenance at all..No one here even paints the steel beams..
The problem that we had with our fiber wraps was every 2 years Ga DOT inspects all bridges in the state and they didn't raise the rating on the bridges due to the fiber wrap, some states may, but IMO as a former "County Engineer" what they care about is extending the bridge life and getting the rating raised so I would factor that into your salespitch..
