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 mostly complete in early 2005, the section of Interstate passing through central Boston, Massachusetts was largely underground. As of April 19, 2005, the tunnel is mostly complete, but greenification from the above-ground area that was removed because of the Dig has still to be completed. The entire project is to be completed in early-mid 2006. The costs are mounting though, with a official budget of $17.6 billion, but a realistic amount of up to $22 billion. It is the most expensive road construction project in the USA.
As part of the Big Dig, I-90 was extended east to connect with I-93 and Logan Airport.
Interstate 93 is not tolled in any way because of the Big Dig, but the toll road Interstate 90 was extended to East Boston, where Logan Airport is.
Notes
- An 8 mile (13 km) section of I-93 through Franconia Notch State Park, called the Franconia Notch Parkway in New Hampshire, was constructed as a "Super-2" with a median divider. This was built as a compromise to environmentalists who were strongly opposed to the idea of a 4-lane freeway in the area. The speed limit on the Parkway is 45 mph (70 km/h). Originally, this section had its own exit number sequence, but they are now called Exit 34A, 34B and 34C.
