State Rep. Christine Barber on why the Green Line needs to go to Route 16

"Op-Ed: Build The Green Line Extension To Rt. 16" (Somerville Patch) "The GLX stop at Route 16 not only brings public transportation access to a number of environmental justice communities, but would connect a greater region of car-centric suburbs to help provide an easy, accessible transit option for thousands of people in the Medford, Arlington, and Somerville area and beyond.

Environmental review of Green Line Extension to Mystic Valley Parkway

The MBTA has now released a preliminary environmental document for this separate project. On October 17, 2017, the MBTA filed a Notice of Project Change (NPC) with the Executive Office of Energy and Environmental Affairs…

Green Line public meeting notes

Thanks to Ken Krause for the following notes from Monday’s meeting at Somerville High School…


+ Program Manager John Dalton reported that the process of selecting a contractor to complete the design and construction of GLX Phase I was nearing completion. (Phase I would extend the Green Line from a relocated Lechmere Station to College Avenue in Medford, with a separate spur extending from Lechmere to Union Square in Somerville. Phase II would further extend the Medford leg of the extension to Route 16 on the Medford/Somerville border.)

+ Three joint ventures bid on the Phase I “design-build” contract, and two of the bids have been certified as being within the “affordability limit” of the remaining project budget of $1.319 billion (the total budget, including money already spent and for 24 new Green Line cars, is $2.289 billion).

+ It will not be known until the bids are opened publicly on November 17 whether any of them include any of the six “additive options” that were cut from the original project; bidders were asked to try to fit as many of these as possible into their proposals while remaining within the budget. The additive options, which must be added in this order of priority determined by the MBTA, are 1) Platform canopies at each station; 2) Additional elevators at select stations; 3) Public art; 4) Additional connection to the Community Path at Chester Street in Somerville; 5) Extension of the Community Path between East Somerville and Lechmere Stations. 6) Enhanced Green Line vehicle maintenance facility in Somerville.

+ The MBTA plans to announce the selected design-build contractor and issue a Notice to Proceed on December 11, 2017. “Right now,” Dalton said, “we have everything in place that we need to get this project off the ground by then end of this year.” The Green Line extension is anticipated to be in operation four years later, in December 2021.

Green Line contractor bids coming in

"Bids for extending the Green Line are due Thursday" (Boston Globe) "...the agency is asking the bidders to revive parts of the project that were unceremoniously dumped in 2016 in the face of a billion-dollar overrun, such as canopies over train stops, and the final 3,000-foot stretch of a bike and walking path to be built alongside the rails. As part…
