Red Blue Connector

An update on tunnel constructability and land use from the 2010 DEIR

In 2018, MassDOT conducted analysis to revisit assumptions from the 2010 Draft Environmental Impact Report (DEIR) for a project to extend the Blue Line from Bowdoin to Charles/MGH under Cambridge Street to create a transfer to the Red Line. The analyses posted here focused on constructability of the tunnel and the changes in land use, demographics, and ridership.

The Office of Transportation Planning presented to the FMCB and MassDOT Boards on the findings from the market analysis on September 17, 2018 and the constructability analysis on October 15, 2018.
