> a structural engineering professor at the Politecnico di Milano, Carmelo Gentile, found troubling signals of corrosion or other possible damage...he has performed his tests on some 300 bridges around the world It would be very interesting to know what he had to say about the other 299 bridges. After all, you can find someone who will tell you you have a structural problem with the safest bridge. It's hard to tell if they are a crank, someone with a vested interest, someone seeking publicity for their new diagnostic method, or genuinely an expert who is giving you good advice. But if Professor Gentile mostly says the bridges are fine, but singled out this one as a danger - then it's really worth listening to his other recommendations.
