Ahem; as a Bostonian parachuting in I would like to say that in the context of what was being done, the Big Dig was well managed. They used the existing Elevated Artery as support struts to tunnel underneath, extended 90 under Fort Point to Logan, reconnected the North End to Boston, all while not shutting down any roads. They performed the equivalent of brain surgery on a patient while still awake. Is there certain things I’d like them to have done better? Yes (don’t source screws from a negligent contractor, actually build NSRL while your at it, built housing on the useless green space). But by and large, I think you can argue it was the most successfully run mega project in the US since LBJ.
