Following up on the previous announcement on October 17, the MBTA is today reminding riders that Green Line service will be suspended between Union Square and Lechmere November 11 – 17. This service suspension will be extended between Park Street and Union Square as well as East Somerville beginning at 8:30 p.m. through the end of service on November 15, continuing all day through the weekend of November 16 – 17. 

Riders can find complete information at mbta.com/GreenLine. More information on these service changes and alternate travel options is below: 

• November 11 – 17: Between Lechmere and Union Square 

• Riders should note there will be no shuttle bus service to Union Square. Green Line Union Square Branch riders can instead use area bus routes, including the 86, 91, and CT2 between Union Square and East Somerville station on the Medford Branch. These bus routes also travel to Sullivan Square on the Orange Line. In addition, Route 87 travels between Union Square and Lechmere. 

• Riders using local buses during these service changes should budget extra time. For example, a rider traveling to Park Street from Union Square should budget at least 10 minutes of travel time in addition to their regular commute. 

• Beginning at approximately 8:30 PM through the end of service on November 15, continuing each day November 16 – 17: 

• Between Park Street and Union Square / East Somerville 

• Free and accessible shuttle bus service will replace trains between North Station and East Somerville. The shuttle will also serve Sullivan Square for an additional Orange Line connection.  

• Green Line service between Medford/Tufts and East Somerville will be fare-free. 

• Riders should note that there will be no shuttle bus service between North Station and Park Street. Riders should instead utilize the Orange Line for parallel service through North Station and Park Street. 

• Riders are also reminded that Orange Line / Green Line connections can also be made via the Winter Street Concourse, which connects Park Street and Downtown Crossing stations. 

• Riders should note there will be no shuttle bus service to Union Square. Green Line Union Square Branch riders can instead use area bus routes, including the 86 and 91 between Union Square and East Somerville station on the Medford Branch. These bus routes also travel to Sullivan Square on the Orange Line. In addition, Route 87 travels between Union Square and Lechmere. 

This service change is in place to perform lighting work and prepare this Green Line area for upcoming Track Improvement Program work taking place in December. The Track Improvement Program will replace tracks and ties to alleviate speed restrictions along the line while crews maximize the outage by performing signal work and station amenity upgrades, including new lighting, painting, tiling, power washing, and more. 

The MBTA understands how these service changes affect riders’ daily travels during this period, but we are committed to improving your travels long term with more reliable, timely, and safe service. We thank riders for their patience as we deliver this important work and for continuing to ride our system. 

More information is also available through in-station signage and public announcements. Transit Ambassadors and MBTA staff will be available on-site to offer information and assistance during these service changes. Riders are encouraged to subscribe to T-Alerts or to follow the MBTA on X @MBTA for up-to-date service information. 

Riders are also encouraged to connect with MBTA staff at the following upcoming Track Improvement Program pop-up event:
