The construction of the multi-level Cogswell Interchange in 1970 separated Barrington Street into two discontinuous sections; the street now interchanges with itself at this point. That is, a driver heading south toward downtown who exits Barrington at the Cogswell Interchange will wind up on the south section of Barrington Street. Continuing straight through the interchange, Barrington splits into Hollis Street and Lower Water Street. The Cogswell Interchange is slated to be demolished in the near future. In the current redevelopment plans, Barrington Street would form a continuous street once again.
