The project's cable-stayed bridge across the Charles River consumed 1,820 miles (2,929 km) of steel wire and 150 cranes were used project-wide. 25% of the project's construction time was completed in the first 5 years with total construction reaching around 94% complete by 1994.

Partnering activities included leadership training, seminars, and executive meetings. Federal and state government officials and the contractors’ project management teams met regularly with an independent expert to assist in developing a single, integrated team. Sharing knowledge, risk, and liability, partnering reduced the cost of contractor claims, increased the number of value-engineering savings proposals, and helped keep projects on schedule. a b "The Mysterious Corroding Big Dig Light Fixtures". boston.com.

The project replaced Boston's deteriorating six-lane elevated Central Artery (I-93). It did so with an underground highway that is state of the art and two new bridges over the Charles River. It also extended I-90 to Boston's Logan International Airport, and Route 1A. This project created more than 300 acres of open land while reconnecting downtown Boston to the waterfront.

To build slurry walls past these tunnels, it was necessary to dig beneath the tunnels and to build an underground concrete bridge to support the tunnels' weight, without interrupting rail service. a b "Report: Even More Big Dig Leaks Found".

Boston'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) Excavators are essential for construction projects, offering a range of functions beyond just digging. Whether you need to move materials, demolish structures, or shape terrain, an excavator is the workhorse you need. DETROW: Ian Coss hosts The Big Dig, and he joins me now to talk about what we can learn today in this moment of infrastructure building from America's most expensive highway project. Hey, Ian.Palmer, Thomas (June 21, 1994). "State Wins Federal OK to Start River-Crossing Part of Artery Project". Boston Globe. Archived from the original on November 5, 2007 . Retrieved December 10, 2007. The Commonwealth of Massachusetts was required under the Federal Clean Air Act to mitigate air pollution generated by the highway improvements. Secretary of Transportation Fred Salvucci signed an agreement with the Conservation Law Foundation in 1990 enumerating 14 specific projects the state agreed to build. This list was affirmed in a 1992 lawsuit settlement. [35] While not a legally mandated requirement, public art was part of the urban design planning process (and later design development work) through the Artery Arts Program. The intent of the program was to integrate public art into highway infrastructure (retaining walls, fences, and lighting) and the essential elements of the pedestrian environment (walkways, park landscape elements, and bridges). As overall project costs increased, the Artery Arts Program was seen as a potential liability, even though there was support and interest from the public and professional arts organizations in the area.

From long-reach machines for dredging to high-reach machines for demolitions, these powerful and versatile excavators are built to handle any task.

Safety Board Determines Cause of Boston's Big Dig Tunnel Ceiling Collapse Last Year". ntsb.gov. October 5, 2007. Archived from the original on October 16, 2007 . Retrieved July 12, 2006. The Rose Fitzgerald Kennedy Greenway is a roughly 1.5-mile-long (2.4km) [8] series of parks and public spaces which were the final part of the Big Dig after Interstate 93 was put underground. The Greenway was named in honor of Kennedy family matriarch Rose Fitzgerald Kennedy, and was officially dedicated on July 26, 2004. To put that into perspective, courtesy of WBUR, here are some other largescale projects that were actually cheaper: On January 18, 2003, the opening ceremony was held for the I-90 Connector Tunnel, extending the Massachusetts Turnpike (Interstate 90) east into the Ted Williams Tunnel, and onwards to Boston Logan International Airport. The Ted Williams tunnel had been completed and was in limited use for commercial traffic and high-occupancy vehicles since late 1995. The westbound lanes opened on the afternoon of January 18 and the eastbound lanes on January 19.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. [1] COSS: And so part of what I wanted to do with the series was to show how we got there, because it's complicated. And it's not as simple as, you know, there was just one corrupt politician or one single, greedy contractor who came in and ruined the whole thing. I mean, the challenges and obstacles that the Big Dig faced are really systemic challenges to the way we build infrastructure in this country. And it's about kind of wonky stuff like funding and permitting and contracting and management structure and things, like I said, that are systemic to all big projects. So if you're interested in building high-speed rail or building wind farms or tearing down highways or doing anything big and ambitious, the Big Dig really is a great case study for understanding how hard those projects are. A number of public transportation projects were included as part of an environmental mitigation for the Big Dig. The most expensive was the building of the Phase II Silver Line tunnel under Fort Point Channel, done in coordination with Big Dig construction. Silver Line buses now use this tunnel and the Ted Williams Tunnel to link South Station and Logan Airport. Johnson, Christine M.; Edward L. Thomas (October 1999).
