Project Updates

The Central Artery/Tunnel Project in its final stages of construction remains the largest and most complex highway and tunnel project in the nation's history. There is broad input and oversight of the Project by numerous entities, and Project managers prepare an extensive monthly report, the Project Management Monthly (PMM), to track the $14.6 billion budget and schedule. The PMM, the annual Finance Plan, a timeline/schedule and other reports and publications are presented in this Project Update section.
