MassDOT / GLX Update Emails

MassDOT and the GLX team maintain an email list, available to anyone wishing to opt in. Emails include upcoming schedules and work information. To sign up for these email updates, visit www.greenlineextension.org.


Station-Area Representatives

The GLX Project team developed a Community Working Group to provide information sharing between the project team and the public. The Working Group consists of representatives from each of the station areas in Medford, Somerville, and Cambridge. Working Group members provide assistance to the MBTA and to the community in identifying local issues of concern, facilitating dialogue, and planning agendas and topics for discussion at neighborhood and community meetings. We strongly encourage you to reach out the Working Group representative closest to your area of interest and sign up for their alerts and updates. These representatives work very closely with the project team and the City of Somerville and can provide you with valuable information for your specific neighborhood. The representatives for each area are listed below along with their contact information.
