Big Dig

Interstate 93 is famous for being reconstructed by the Big Dig, the most massive urban construction project in history. After this project was considered complete in late 2003, the section of Interstate passing through central Boston, Massachusetts was largely underground.

As part of the Big Dig, I-90 was extended east to connect with I-93 and Logan Airport.
