The Boston Central Artery/Tunnel project is America's largest public works project today. It encompasses the new Ted Williams Tunnel between south Boston and Logan Airport, which is currently open to traffic, and the rebuilding of the Central Artery (I-93) which is (as of mid-2002) nearing completion. The new Artery will run underground through the heart of downtown Boston, and will be constructed underneath the existing elevated structure.
