Big Dig

The Big Dig was a massive construction project in Boston, completed in the early 2000s, aimed at improving the city's traffic flow and replacing the elevated highway known as the Central Artery. The project's centerpiece was the construction of tunnels to bury the highway underground, freeing up space for parks and urban development. It addressed safety and congestion issues but was also known for its budget overruns and delays, making it one of the most expensive highway projects in U.S. history. Overall, the Big Dig transformed Boston's infrastructure and urban landscape.
