That's what they said about the big dig. Now that it's all said and done it's still the go to example of a boondoggle public works project that turned into a money fountain for anyone who knew a guy who knew a guy who knew a guy in government. (In the project's defense, it did increase throughput and alleviate some traffic problems on surface streets which was the goal.) The north/south station rail connector that was supposed to be thrown in never even happened which the city has been kicking itself over for years.

Don't count your chickens before they hatch. Of course when they do hatch you'll wish you had twice as many eggs to start with. Boston sure wishes it has the inner belt along with all the various rail projects it's forgone over the years.
