Amazon could be the trigger that finally connects Red to Blue for the T.
According to Curbed Boston, “the connection would be pretty simple on paper: The Blue Line would be extended from its Bowdoin terminus to the Red Line’s Charles/MGH stop.” Curbed further notes that a connection between the two T-lines “has been a what-if since at least the Big Dig, which was supposed to produce the link as a byproduct (probably via a 1,500-foot, $750 million tunnel along Cambridge Street). That never happened.”
