Boston's 'Big Dig' opens to public". NBC News. Associated Press. December 20, 2003 . Retrieved March 30, 2019. The Central Artery/Tunnel Project ( CA/T Project), commonly known as the Big Dig, was a megaproject in Boston that rerouted the Central Artery of Interstate 93 (I-93), the chief highway through the heart of the city, into the 1.5-mile (2.4km) Thomas P. O'Neill Jr. Tunnel. The project also included the construction of the Ted Williams Tunnel (extending I-90 to Logan International Airport), the Leonard P. Zakim Bunker Hill Memorial Bridge over the Charles River, and the Rose Kennedy Greenway in the space vacated by the previous I-93 elevated roadway. Initially, the plan was also to include a rail connection between Boston's two major train terminals. Planning began in 1982; the construction work was carried out between 1991 and 2006; and the project concluded on December 31, 2007, when the partnership between the program manager and the Massachusetts Turnpike Authority ended.

The project received approval from state environmental agencies in 1991, after satisfying concerns including release of toxins by the excavation and the possibility of disrupting the homes of millions of rats, causing them to roam the streets of Boston in search of new housing. By the time the federal environmental clearances were delivered in 1994, [25] the process had taken some seven years, during which time inflation greatly increased the project's original cost estimates.

The original Big Dig plan also included the North-South Rail Link, which would have connected North and South Stations (the major passenger train stations in Boston), but this aspect of the project was ultimately dropped by the state transportation administration early in the Dukakis administration. Negotiations with the federal government had led to an agreement to widen some of the lanes in the new harbor tunnel, and accommodating these would require the tunnel to be deeper and mechanically vented; this left no room for the rail lines, and having diesel trains (then in use) passing through the tunnel would have substantially increased the cost of the ventilation system.
