Boston Green Line Repairs Set Stage for Safer Transit

MBTA closes two Green Line branches through Dec 22 for track and signal repairs

Green Line Shuts Sections for Track Repairs

Boston transit riders face service disruptions on two Green Line branches through December 22 as the MBTA conducts track and signal maintenance work. The E branch between Lechmere and Union Square closed December 14, while the D branch between Government Center and Medford/Tufts shut down December 16, transit officials said. The agency's providing shuttle bus service on affected sections, though specific details about the number of buses deployed weren't available.

The maintenance work targets track and signal systems that require repair to maintain long-term reliability and safety, according to the transit agency. Officials described the closures as essential maintenance but didn't provide detailed specifications of the repair activities being performed. The Green Line serves approximately 143,000 weekday riders system-wide, though the MBTA hasn't specified how many passengers are affected by the partial closures. Transit agencies typically conduct multi-day service shutdowns to complete infrastructure work faster than overnight or weekend maintenance windows would allow.

The closures affect recently expanded portions of the Green Line system. The Medford/Tufts and Union Square branches opened in March 2022 as part of the Green Line Extension project, completing a decades-long expansion effort. Officials said the current maintenance work is necessary for the system's infrastructure but haven't disclosed the total cost of the repair project. The MBTA has conducted multiple planned service shutdowns throughout 2024 as part of broader system modernization efforts, reflecting increased focus on addressing deferred maintenance under federal safety oversight.

Service is scheduled to resume December 22 on both affected branches, officials confirmed. The timing means repairs will conclude before the Christmas holiday travel period. The MBTA typically announces major service changes several weeks in advance, though officials didn't specify when riders received initial notification about these closures. The agency said shuttle buses are running on routes matching the closed sections to maintain connectivity during the repair period.

Riders should plan for longer travel times and consider alternative routes during the closure period. Other Green Line branches continue normal service, and connections to other MBTA subway lines remain available at transfer stations. Officials said passengers should allow extra time for their commutes through December 22.
