The Rose Fitzgerald Kennedy Greenway is a roughly 1.5-mile-long (2.4 km) series of parks and public spaces which were the final part of the Big Dig after Interstate 93 was put underground. As a result of a death, leaks, and other design flaws, Bechtel and Parsons Brinckerhoff-the consortium that oversaw the project-agreed to pay $407 million in restitution and several smaller companies agreed to pay a combined sum of approximately $51 million. The Boston Globe estimated that the project will ultimately cost $22 billion, including interest, and that it would not be paid off until 2038. However, the project was completed in December 2007 at a cost of over $8.08 billion (in 1982 dollars, $21.5 billion adjusted for inflation, meaning a cost overrun of about 190%) as of 2020.

The project was originally scheduled to be completed in 1998 at an estimated cost of $2.8 billion (in 1982 dollars, US$7.4 billion adjusted for inflation as of 2020 ). The Big Dig was the most expensive highway project in the United States, and was plagued by cost overruns, delays, leaks, design flaws, charges of poor execution and use of substandard materials, criminal charges and arrests, and the death of one motorist. Planning began in 1982 the construction work was carried out between 19 and the project concluded on December 31, 2007, when the partnership between the program manager and the Massachusetts Turnpike Authority ended. Initially, the plan was also to include a rail connection between Boston's two major train terminals. 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.

The project also included the construction of the Ted Williams Tunnel (extending I-90 to Logan International Airport), the Leonard P. 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 (2.4 km) Thomas P. 42☂1′43″N 71☀3′20″W / 42.36197°N 71.05562°W / 42.36197 -71.05562īoston's highway system before and after the Central Artery/Tunnel Project Boston's highway system before and after the Central Artery/Tunnel Project (static image)
