Boston's Big Dig

Boston's Big Dig was a massive infrastructure project to reroute the Central Artery, a highway that ran through downtown Boston, underground. Completed in the early 2000s, it aimed to reduce traffic congestion, improve air quality, and revitalize the city. The project included building new tunnels, parks, and public spaces. While it successfully transformed the urban landscape, it faced significant delays, cost overruns, and engineering challenges, ultimately costing about $15 billion. The Big Dig is often seen as both an engineering marvel and a cautionary tale about large-scale public works projects.
