Project Description:
Boston's Central Artery/Tunnel, owned by the Massachusetts Highway Department, is the largest and most complex highway project ever undertaken in an American city. The project is transforming downtown Boston as the aging and overly congested elevated expressway is replaced with a new underground interstate system and a third harbor tunnel. Opened in 1995, the new Ted Williams tunnel extends the Massachusetts Turnpike under Boston Harbor to provide improved access to Logan International Airport.

Transdyn is providing the Integrated Project Control System (IPCS) that monitors and controls all aspects of over 150 lane-miles of highway and twenty major operations, emergency response, ventilation, and electrical distribution facilities. The IPCS constantly monitors the roadway and facilities providing computer managed responses to traffic incidents and other adverse conditions in order to maintain life safety and optimal traffic flow.
