Area

The study area is made up of two parts:

The core study area is where all proposed alternatives and extensive traffic analysis will take place. It includes the Massachusetts Turnpike, I-90, from the Commonwealth Avenue overpass in the west to the Harrison Boulevard overpass in the east.
The regional study area consists of the neighborhoods surrounding the core study area where MassDOT will collect existing condition data such as traffic volumes, crash data, environmental information, etc. Later in the study, this regional area will be used to evaluate traffic congestion based on various proposed alternatives. This area includes the South Boston Waterfront, the South End, Chinatown, the Back Bay, Bay Village, the Fenway/Kenmore neighborhoods, the Longwood Medical area and areas in Brookline and Allston out to Harvard Avenue.
