Big Dig (Boston)
As the most expensive highway in US history, the Central Artery and Tunnel — known as “The Big Dig” — started as a $2.6 billion Boston project. By the time it was finished, its cost had ballooned to $15 billion, plus another $9 billion in interest. It was completed 8 years late and was plagued with innumerable errors, such as “design blueprints that didn’t line up properly, to the faulty mixing of concrete,” according to the Boston Globe. Most tragically, a ceiling collapse killed a car passenger.
