Green Line Extension
Due to anticipated cost over-runs, the MBTA undertook a significant redesign of the Green Line Extension project in early 2016. While maintaining the same anticipated service, stations and other facilities were greatly simplified to reduce costs. The redesign effort, combined with funds committed to the project by the Metropolitan Planning Organization, the City of Cambridge and Somerville, the project is looking at next steps to fill the remaining $75m funding gap and renegotiate approvals by the Federal Transit Administration for the federally funded part of the project. No new schedule for the project is available at this time.
On Monday, May 9, 2016, the GLX Interim Project Management Team submitted a report to the MassDOT Board of Directors and the MBTA Fiscal & Management Control Board at a joint meeting.

The Green Line Extension (GLX) project is extending the MBTA's Green Line transit service to the north west, from a relocated Lechmere Station in Cambridge, to a spur ending in Union Square Somerville, and the main line to College Avenue in Medford. From the project web site, benefits will include:
- Provide new and better opportunities for residents and visitors to travel within their communities and within the region, address longstanding transportation inequities.
- Result in fewer automobiles on local roads and help combat greenhouse gas emissions and other components of air pollution.
Support municipal plans for sustainable growth and development.
- Provide residents of environmental justice communities with faster rides to work and other destinations.
Funding has also been set aside to extend the project to Route 16 on the Medford / Somerville line.

At the same time, the relocation of Lechmere Station across O'Brien Highway is being coordinated with the build out of North Point by HYM Development. HYM is responsible for the reconstruction of O'Brien Highway and is working closely with the City of Cambridge and the state to improve existing crossings, and to create new crossings to make the new station readily accessible to the East Cambridge neighborhood.
