Wonderland to Bowdoin.
Accessibility issue: Bowdoin Escalator 125 (Lobby to street) is unavailable until further notice, pending replacement.
The escalator will remain out of service for the foreseeable future. This decision was made after a thorough inspection determined that corrosion on the escalator’s steel truss was so severe that it could not be repaired further and that a complete replacement of the escalator would be required. Replacing the escalator at this location requires a more extended unit meeting modern escalator safety requirements. This longer unit will require significant alteration to the station entrance to meet code requirements. The MBTA has currently begun design work to understand what station upgrades will be needed. Due to these complexities, we expect the escalator will remain out of service for a significant time. We recognize the challenges this poses to our riders, and please know we are working to identify a solution as quickly as possible. In the meantime, Government Center Station, which is fully accessible and serves the Blue Line, is under a quarter-mile from Bowdoin Station.

Medford/Tufts to Heath Street.
No service: Green Line E Branch: Symphony station is closed for major accessibility upgrades. Riders can use Prudential or Northeastern to access E Branch service. Construction is expected to last approximately 3 years.
Alternate Service Options: • Riders who typically board or disembark at Symphony can instead board or disembark at Northeastern University or Prudential, which are 0.3 miles away (or about a five-minute walk) from Symphony. • Riders are encouraged to instead consider travelling on the Orange Line at Massachusetts Avenue, which is 0.1 miles (or about a three-minute walk) from Symphony. • Riders may also use the Route 39, which operates parallel to the E branch in both directions along Huntington Avenue. Background: Currently, there are no step-free pathways from the entrances to the platforms at Symphony, and the station is not able to be accessed by people with wheeled mobility devices. When construction is complete in spring 2029, Symphony will be enhanced with four new accessible elevators, raised platforms for easier boarding, accessible bathrooms, improved wayfinding, more lighting, and upgraded safety features, making the station safer and easier to use for all riders.
