Beginning Saturday, Sept. 24, the Green Line D Branch will close for three nine-day, full-access closures.
The closures will take place on a rolling basis through Sunday, Oct. 30. During this closure, the MBTA will replace track, station crossings, and install wayside equipment for the Green Line Train Protection System (GLTPS).
“These kinds of full-access diversions allow the T to accelerate investments and improvements across the system,” said MBTA General Manager Steve Poftak. “With three full-access diversions already successfully completed on the Green Line this summer, I am confident the Capital Transformation team will complete the D Branch promptly and on schedule, delivering an increased level of safety and reliability to our riders through track replacement work and the installation of GLTPS infrastructure. I want to thank our Green Line riders for their patience while we accomplish this critical work on a faster timeline.”
The Green Line Transformation team already completed three Green Line diversions this summer on the B, C, and E Branches, and the D Branch diversion is the final diversion in this project. The D Branch improvements require some prep work, which will begin Monday, Sept. 19, and end Friday, Sept. 23. Prep work will not interfere with regularly scheduled service.
In order to cause less disruption to Green Line riders, this 27-day, full-access closure will be broken into three nine-day periods:
- Saturday, Sept. 24 – Sunday, Oct. 2
- Saturday, Oct. 8 – Sunday, Oct. 16
- Saturday, Oct. 22 – Sunday, Oct. 30
“The Capital Transformation team continues to work diligently to deliver the best service possible for our riders,” said MBTA Chief of Capital Transformation Angel Peña. “Although this is the last scheduled surge for the Green Line this year, our team is always looking for ways to best serve our riders and deliver the safest and most reliable commute possible.”
During this closure, the MBTA will replace over 6,000 ft of track, upgrade over six station crossings, and install wayside equipment for GLTPS. A majority of the full-depth track replacement will take place between Eliot and Riverside stations.
