Boston Green Line Upgrades to Boost Future Reliability

Green Line's northern branches close Dec 8-22 for track replacement work

Green Line Shuts Down for Two Weeks in December

Boston's Green Line won't run between Government Center and Medford/Tufts and Union Square from December 8 through December 22, transit officials said. The MBTA will replace train service with shuttle buses during the 14-day shutdown for track replacement work. The closure affects the northern branches of one of Boston's busiest transit lines, though specific ridership figures weren't immediately available.

Track Work Part of Modernization Effort

The shutdown is part of the Green Line Transformation program, a multi-year initiative launched in 2021 to modernize infrastructure and improve reliability, according to the MBTA. The affected segment includes portions of the Green Line Extension that opened in March 2022, connecting Medford/Tufts and Union Square to the system. Transit agencies increasingly use concentrated maintenance windows rather than prolonged partial service disruptions, allowing faster completion of necessary work. The MBTA hasn't publicly disclosed the cost of the track replacement project.

Shuttle Buses to Replace Train Service

The MBTA plans to provide shuttle bus service during the shutdown, with specific routes and schedules to be announced closer to the December 8 start date. Officials didn't provide details about how many buses will be deployed or exact shuttle routes. The affected segment serves thousands of daily commuters traveling between downtown Boston and the northern communities. Transit advocacy groups hadn't yet issued public statements on the planned shutdown as of the announcement.

Work Scheduled Through December 22

The track replacement work will continue through December 22, with full Green Line service scheduled to resume December 23. The timing falls during the holiday season, which could affect shoppers and those traveling to seasonal events in the Boston area. Officials said the concentrated two-week shutdown allows the agency to complete necessary infrastructure improvements more efficiently than extended partial closures would permit.

Riders Should Plan Alternative Routes

Commuters who rely on the affected Green Line segment should begin planning alternative transportation now. The MBTA operates other subway lines and bus routes that may serve as options for some travelers during the shutdown. Phillip Eng, General Manager and CEO of the Massachusetts Bay Transportation Authority, oversees the modernization efforts.
