The Big Dig
The Big Dig
Boston's Big Dig was an idea estimated to cost $2.8 billion in 1985 and substantially soared to $14.8 billion, making it the most expensive highway project ever undertaken in history. Beginning in 1991, construction for the Big Dig led to the fatal injuries of four workers and death of a motorist from the collapse of a concrete panel. The expressway system was completed in 2007.
