To be sure, the vast majority of megaprojects around the world bust their budgets, though, for a variety of technical, legal, political and financial reasons. Boston’s 3.5-mile Big Dig, for example, was finished in 2007 — nine years behind schedule and at a cost of $14.6 billion, up from an initial estimate of $2.5 billion. The 11-mile East Side Access tunnel in New York City is 14 years behind schedule, and its tab has grown from $4.3 billion to $11.1 billion.
