November 11 – 17:

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 travelling to Park Street from Union Square should budget at least 10 minutes of travel time in addition to their regular commute.

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.
