Abstract

The Big Dig (Central Artery/Tunnel Project) was mega road infrastructure project which was undertaken in Boston, Massachusetts, USA to improve the flow of traffic and avoid travel congestion across Boston. The project replaced the outdated elevated Central Artery road. The Central Artery/Tunnel project was one of the most challenging project in the history of United States. The project replaced the six lane Central Artery (I-93) with an underground highway and two new bridges over the Charles River. The project undertaken by the Massachusetts Turnpike Authority was initiated in the year 1991. The cost of the project was estimated to be US$14.8 billion. The project was completed in year 2007. The project covered 7.8 miles of highway and 161 lanes miles. The project facilitated 62% reduction in vehicle hours of travel on I-93, the airport tunnels and the connection from Storrow Drive. The new underground route I-93 Central Artery has improved the peak period travel times through downtown Boston. The Big Dig was the most expensive highway project in the US. According to Massachusetts Turnpike Report 2008, the project incurred a final cost of US$ 14.8 billion.
