Link to his Google MapMr. LePatner is a New York construction industry lawyer and author of "Too Big To Fall: America's Failing Infrastructure and The Way Forward." (Go to his site, SaveOurBridges.com, and see if there's a collapsing bridge near you. Maybe you pass beneath one on your drive to work or send your children across it in a yellow bus. Send me an email. I would love to hear what you find.)
Mr. LePatner's map is based on bridges the Federal Highway Administration has deemed both "structurally deficient" and "fracture critical." The first category means one or more defects. The second means no redundant system to keep a bridge in place if one of its parts fails.
These perilous bridges haven't been repaired for the same reason that many other things aren't getting fixed, from the economy on down: Politicians are slaves to corporate masters. They get re-elected for funding new off-ramps at new malls in the new parts of towns.
Maybe it's just a project so he can promote his book, but it's interesting nonetheless.
