Current Costs and Funding of the Central Artery/Ted Williams Tunnel Project

Project ID: 

The Massachusetts Central Artery/Ted Williams Tunnel (Project) will replace Boston's deteriorating elevated highway (part of Interstate 93) with a new underground expressway. The project will also extend the Massachusetts Turnpike (Interstate 90) to Logan Airport. This is a significant project, not only for its role in New England's transportation infrastructure, but for the economic benefits and cost impacts it presents to residents of Massachusetts.
