Which newspaper, reacting to wildly high cost overruns and scandalous cover-ups, ran the sensational headline, "The Big Dig: Bankrupt"? (The Boston Globe, on April 9, 2000.) And how much do you know about this historic construction project-the largest ever attempted? Find out! This fun follow-up to the bestselling The Big Dig and The Big Dig at Night tests your "Dig" smarts with mind-stretching and mind-boggling questions. Chock-full of interesting behind-the-scenes information, the quizzes cover politics, construction, the Williams Bridge, and other info bytes you'll want to know.
