The MBTA announced that upcoming spring service changes for bus and subway will take effect in March 2022, and Commuter Rail and ferry service changes will take effect in May 2022.
SUBWAY SERVICE CHANGES: Effective the afternoon of Monday, March 21, 2022, the Union Square Branch of the Green Line Extension (GLX) will open to MBTA riders. Union Square Station will join the Green Line, and Lechmere and Science Park/West End Stations, which were closed during construction, will reopen. Effective Monday, March 14, 2022, Green Line weekday schedules will shift throughout the day with the Green Line C branch adding one weekday trip. There will be no schedule changes on the Red, Orange, and Blue Lines.
BUS SERVICE CHANGES: The MBTA continues an aggressive hiring campaign for bus operators. While this hiring campaign takes place, bus service changes continue to be made with special focus on maintaining service levels on routes with durable ridership, increasing service on the most crowded routes, adapting service to accommodate new in-person school and work trips, and maintaining the flexibility to make changes to schedules as needed. Some bus schedule changes will go into effect on Sunday, March 13, 2022, though bus service levels this spring will be similar to winter 2022 schedules.
