GLX - Art Commission Project

There are presently no open calls for submissions.


The Green Line Extension (GLX) Project is an initiative of the Massachusetts Department of Transportation (MassDOT) and the Massachusetts Bay Transportation Authority (MBTA).

The project will extend the MBTA Green Line from a new and relocated Lechmere Station in East Cambridge to Union Square in Somerville and to College Avenue in Medford. While proposals to extend public transit service north from Lechmere date back many decades, the current phase of planning began in 2005 with the completion of the MBTA's Beyond Lechmere Northwest Corridor Study. It was a Major Investment Study/Alternatives Analysis that evaluated a wide range of technology and operating plans for the area, including a mixture of Green Line extensions, rapid bus transit, and commuter rail enhancements.  

Bringing MBTA light rail service to this corridor will greatly improve local and regional mobility, thus addressing longstanding transportation inequities. It will also result in fewer automobiles on local roads, which will help to combat greenhouse gas emissions, and other components of air pollution. The Green Line Extension Project will also support municipal plans for sustainable growth and urban redevelopment, while providing residents of environmental justice communities with faster rides to work, and other destinations.

The proposed service consists of two distinct parts: the "mainline" and the "branch". The mainline will operate within the existing right-of-way of the MBTA Lowell Line. It will begin at the new Lechmere Station in Cambridge and travel north to Medford. The branch line will operate within the existing right-of-way of the MBTA Fitchburg Line and it will travel to Union Square in Somerville. There will be seven new stations constructed as part of the project, including the relocated Lechmere Station. A vehicle storage and maintenance facility will also be constructed.  Once completed, trains will operate every five to six minutes in the peak periods, providing fast and efficient service to downtown Boston.

In conjunction with the Cambridge, Somerville and Medford Art Councils, the MBTA will commission multiple artists to design artistic elements of the GLX stations. The art component of the stations must be integrated into their design. There is a desire for the artwork to provide a unifying factor throughout the transit system, while still managing to distinguish the station platforms from one another and enhancing the rider's travel experience. It is envisioned that this will happen through artistic treatment of:

- Fences
- Screen Walls
- Railings
- Porcelain Enamel Panels
- Site Elements
- Retaining Walls
- Glazing
- Lighting
- Ceilings
- Tile Wall Surfaces
+ Additional Features
