The Back Bay / South End Gateway Project is located at Back Bay Station (145 Dartmouth Street) and the 165 Dartmouth Street Garage, at the border of the South End and Back Bay.

In March of 2016, Boston Properties, LP, filed a Project Notification Form (PNF) proposing an expansion to the 165 Dartmouth Street Garage and Back Bay Station, which was initially built on air rights above the Massachusetts Turnpike in the late 1980s. The proposed project is conceived as a transformative, mixed-use, transit-oriented redevelopment, which will revitalize an underutilized urban site and transform the adjacent public realm, and integrate and connect the surrounding Back Bay, South End, and Bay Village historic neighborhoods.

The proposed project is comprised of up to approximately 1.26 million square feet of mixed-use redevelopment, consisting of a new office building with ground floor retail, two new residential buildings, a one- to two-story vertical retail expansion of the existing Back Bay Station building, and the partial redevelopment of the existing 165 Dartmouth Street Garage.

Citizens Advisory Committee: The Back Bay / South End Gateway Project Citizens Advisory Committee (CAC) is made up of residents, business owners, community organizations, and professionals. Mayor Martin J. Walsh appointed the CAC in April of 2016 to review and guide the proposed development by Boston Properties at the project site. The CAC will be responsible for assisting the BRA with review of development scenarios, urban design, transportation impacts, and mitigation during the Article 80 review process. All CAC meetings are open to the public.
