Ames Street Development

New Construction

Ames Street is transforming into an exciting and active urban corridor. The first infill development project, 75 Ames, was completed by the Broad Institute in 2014. Across the street at 88 Ames, a new residential building is under construction. The building, named the Proto, and owned by Boston Properties, will provide 249 units of market rate housing and 31 units of below market rate housing. Occupancy is expected in the summer of 2018.

Ames Street Streetscape

Ames Street will become more pedestrian-friendly, with new ground floor retail activating the street. Public plaza spaces are also planned for both sides of the corridor, as well as a new pedestrian alleyway between 88 Ames and 355 Main Street, named Pioneer Way. A protected bicycle lane will also be installed to provide a link from the 6th Street Walkway and Broadway to Main Street.

Streetscape Redesign

A section of Binney Street (from 3rd to Fulkerson), Galileo Way and a portion of Broadway (from Ames to Galileo) is undergoing streetscape redesign. The plans will incorporate a continuous raised cycle track, new landscaping and protected bike intersections. It will connect the cycling infrastructure on Vassar Street to the new cycle track on Binney Street between 1st and 3rd.

This project is a collaboration between the CRA, the Department of Public Works (DPW), Traffic Parking & Transportation (TPT), and the Community Development Department (CDD). The project is being funded by the CRA, from monies generated within the Kendall Square Urban Renewal Area. Once streetscape designs are selected, they will be used by property owners to construct the aformentioned improvements in phases over the next 3-10 years.

Infill Development Concept Plan (IDCP)

In February of 2017, The CRA Board and Planning Board approved the MXD District in Kendall Square's Infill Development Concept Plan (IDCP). The IDCP is a concept plan required to be created and approved by the CRA and City, as a result of the major KSURP amendment passed in December of 2015. The concept plan was informed by the K2 planning process, and lays out the urban design, circulation, open space and phasing of new development in the MXD District.


Working closely with the City of Cambridge (City), the Massachusetts Department of Transportation (MassDOT), the MBTA, and Boston Properties (BP), the Cambridge Redevelopment Authority (CRA) has created a mechanism and governance structure for funding public transit to serve the growing Kendall Square district. This Kendall Square Transit Enhancement Program (KSTEP) grew out of the Massachusetts Environmental Protection Act (MEPA) review process for the amendment of the Kendall Square Urban Renewal Plan (KSURP).  As the amendment provides additional development rights within the MXD District of Kendall Square, the KSTEP program is an important mitigation component of the 2015 Environmental Impact Report (EIR), which preceded the approval of the KSURP amendment and zoning entitlements.

The program began with an initial $6 million fund for investment in local transit improvements to the MBTA or other operators, such as the EZ Ride shuttle, that produce a measurable improvement in transit access to Kendall Square. It is expected that the projects to receive investment from KSTEP will be informed by the outcome of the Kendall Square Mobility Task Force planning effort, facilitated by MassDOT and the City.  An additional $3 million payment from Boston Properties to the KSTEP fund was received upon issuance of the 145 Broadway building permit in March of 2017, followed by a $3 million dollar match from the CRA. The CRA has discussed the expansion of the program with other property owners anticipating new development in Kendall Square.

About The Cambridge Center Master Plan 1979-2015

The Kendall Square Urban Renewal Plan (KSURP) includes a major urban mixed-use project on a 24-acre site within the 42-acre Kendall Square Urban Renewal Area, directly across the Charles River from downtown Boston. The Cambridge Redevelopment Authority (CRA) assembled properties, prepared the site for development, and constructed public improvements. Through a public competition, the CRA selected Boston Properties as the master developer that continues to facilitate development.

The Master Plan provides for over 4 million square feet (as of December 21, 2015) of new development in 19+ buildings across three development blocks.  The project accommodates a wide range of complementary uses: first-class office space and biotechnology laboratory space; hotel and retail space; more than 150,000 square feet of major public open space, parks, and plazas; and future residential buildings opening in 2018 and beyond. 

As of December 21, 2015, the City Council passed a major amendment to the KSURP in order to accommodate additional development planned for by the City of Cambridge's K2 Planning Process. The K2 Plan anticipated capacity for up to one million additional square feet of development, including 400,000 square feet of housing.
