Central Artery Tunnel Project - Massachusetts Highway Department

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.
