The Grand Junction multi-use path is envisioned to be an off-street bicycle and pedestrian path connecting the Boston University Bridge on the Charles River to the Somerville Community Path. The first segment of the path, shown in the image above, has already been built by the Cambridge Redevelopment Authority in Kendall Square. The path's design also plans for future two-track passenger transit service, which will be led and implemented by the state.

The CRA is conducting a study to investigate the feasibility of future rail transit service along the Grand Junction. The study will seek to identify feasible options for a rail transit service along the Grand Junction rail line connecting Allston/West Station, Cambridgeport, the MIT campus, Area 4/The Port, Kendall Square, North Point, and Allston/West Station. The study will evaluate issues related to corridor right-of-way, service characteristics (vehicle technology, stations served, frequency), and potential ridership estimates.

The City of Cambridge is planning to design and construct the remaining portions of the proposed multi-use path along the Grand Junction corridor. See the button below for their project website and most recent updates.

On June 9, 2016, the CRA completed construction of Grand Junction Park and the first section of the Grand Junction Greenway multi-use path. Initially proposed as part of the "Innovation Boulevard" project to redesign Galileo Galilei Way in the late 2000s, the first phase of the Grand Junction Greenway was built on land owned by the CRA adjacent to the railroad right-of-way.
