Green Line Extension Update

The MBTA today announced that the work to re-gauge the track along the Green Line Extension (GLX) will not be completed by Monday, December 11, as initially anticipated under the plan presented by the project’s contractor, GLX Constructors (GLXC), which requested additional time of the MBTA. The MBTA has granted the contractor an additional seven nights to continue the work – until at least Sunday, December 17. Evening Green Line trains on both the Union Square and Medford/Tufts branches of GLX have been replaced with shuttle bus service beginning at 8:45 PM since November 27, which will continue during this time.

“The MBTA is committed to ensuring that GLXC completes this work safely, thoroughly, and expeditiously. We are disappointed that they could not complete their work on the Green Line Extension on the timeline that they previously projected and, at our direction, they will be bringing in more resources, including more crews," said MBTA General Manager and CEO Phillip Eng. "We apologize to riders for this inconvenience, and we will continue to do everything in our power to deliver the longer-term, safe, and reliable service that they expect and deserve."

The MBTA is committed to ensuring that GLXC completes this work correctly and safely. The MBTA has directed GLXC to provide additional resources to accelerate the repair work. Following GLXC’s request for additional evening suspensions in GLX service, the MBTA also directed GLXC to submit the complete list of their staff, staff experience level of the on-site workforce who will be committed and held accountable for completing the work, and a production schedule that includes GLXC’s full list of resources dedicated to this effort.

In close coordination with GLXC, the MBTA is committed to accomplishing the GLX narrow-gauge repairs as efficiently as possible while minimizing impacts to riders. The MBTA is committed to reporting this progress and will share more with the public on any plans to further disrupt service in order to complete this narrow-gauge work following additional review of work.
