Any time there is some sort of overpriced boondoggle infrastructure project it gets compared to Boston's Big Dig project. Sure, there's plenty to criticize about the cost overruns, how it was managed, construction problems, delays, etc... That's a lot to criticize! But what too often gets lost is that the Big Dig was a good, if imperfect, project. Whether or not it was "worth it" is too complicated of a question, but ultimately the result is pretty good.
