===Progettazione iniziale===

Il progetto venne studiato negli [[anni 70]] dal consorzio di Boston per la pianificazione dei trasporti per rimpiazzare l'ingombrante Arteria Centrale a sei corsie. La tangenziale separava il centro cittadino dalla costa ed era strozzata dal traffico che incrementava. I dirigenti delle imprese erano più preoccupati circa l'accesso all'aeroporto Logan [[Logane Airport]],spingevano andper pushedun insteadterzo fortunnel aper thirdil harbor tunnelporto. In their second terms, [[Michael Dukakis]] (governor) and [[Fred Salvucci]] (secretary of transportation) came up with the strategy of tying the two projects together—thereby combining the project that the business community supported with the project that they and the City of Boston supported.{{Fact|date=February 2007}}

Planning for the Big Dig as a project officially began in 1982, with environmental impact studies starting in 1983. After years of extensive lobbying for federal dollars, a 1987 public works bill appropriating funding for the Big Dig was passed by [[Congress of the United States|U.S. Congress]], but it was subsequently vetoed by President [[Ronald Reagan]] as being too expensive. When Congress [[Veto override|overrode]] his veto, the project had its green light and ground was first broken in 1991.<ref>Dan McNichol and Andy Ryan, ''The Big Dig''. Silver Lining Press, 1991</ref>
