What worries me is the way we take these things for granted, as though it's a capital asset that we no longer need concern ourselves with. The underground infrastructure in NYC is now covered with massive investments that will make it far more difficult to update than it was to build originally.

And as many commentators have pointed out, it's a lot more sexy for Congress to bring home a new $$ bridge project than to allocate funds to repair or retrofit old ones.
