Scope Of Work
The most complex urban transportation project in U.S. history
The Boston Central Artery/Tunnel project represented public works on a scale comparable to some of the great projects of the previous century?the Panama Canal and the Channel Tunnel. It received dozens of awards for engineering excellence and aesthetics.
The immense project?the result of more than 30 years of planning and 12 years of construction?replaced the elevated section of Interstate 93 Central Artery through downtown Boston with a much wider underground highway, and extended the Interstate 90 turnpike to Logan International Airport via a third harbor tunnel. Bechtel and its joint-venture partner, Parsons Brinckerhoff, provided overall program management for the project.
The project significantly reduced traffic congestion and improved mobility in one of America's oldest and most congested major cities. In addition, it helped improve the environment, and it established the groundwork for continued economic growth for Massachusetts and New England.
