The Big Dig is the unofficial name of the Central Artery/Tunnel
Project (CA/T), a massive undertaking to route the Central Artery (Interstate 93), the chief
controlled-access highway through
the heart of Boston,
Massachusetts, into a tunnel under the city, replacing a previous elevated
roadway. The project also included the construction of the Ted Williams Tunnel
(extending Interstate 90 to Logan
International Airport) and the Zakim Bunker Hill
Bridge over the Charles River.
At the time, the Big Dig was the most expensive single highway project in
American history. When the last major highway section opened in December
2003, over $14.6 billion had been
spent in federal and state tax
dollars.
