The Big Dig

The Big Dig refers to a massive highway project in Boston, Massachusetts, that took place from the late 1980s to the 2000s. Its main goal was to reroute the city's elevated Central Artery freeway into a tunnel, reducing traffic congestion and improving city aesthetics. The project also included new bridges and roads. While it helped modernize Boston’s infrastructure, it faced significant challenges, including budget overruns and construction delays, ultimately costing around $15 billion. The Big Dig is known as one of the most ambitious and complex urban construction projects in U.S. history.
