Not to be too skeptical, but the standard questions apply:

1. What was the sample size (or a census?)
2. Do the authors have a financial interest in the outcome?
3. Who funded the study?

I know in CT, every bridge gets inspected every ten years, and those in bad shape get more frequent inspections. There isn't enough money to fix them all. We spend way way more on entitlements than public safety issues like this one.
