Abstract: One of the most ambitious infrastructure megaprojects in recent memory, Boston's $5 billion Central Artery runs the gamut of civil engineering disciplines. Design, highway, construction, transportation and geotechnical engineers, as well as urban planners will have a hand in the project. When completed in 1998, the Central Artery could trigger long-term changes in Boston, such as improved traffic patterns, more riverside parks, reunited neighborhoods, redesigned streets and more development around Logan International Airport. One portion of the CA/T project—which is symbolic of all its challenges—is the construction of a state-of-the-art immersed tube tunnel beneath Boston Harbor, part of the Interstate 90 extension to Logan Airport. Steel tube tunnel fabrication, trench excavation, tube placement, blasting in the harbor and scheduling/construction impacts on harbor traffic all will play a role in the successful completion of the ITT.
