REMINDER: Blue Line Service Will Be Suspended Between Bowdoin and Airport Evening of September 19 Through September 21

This notice serves as a reminder of the upcoming Blue Line closure previously announced on August 22.

The MBTA is today reminding riders that Blue Line service will be suspended between Bowdoin and Airport beginning at approximately 8:30 PM through the end of service on September 19 and continuing through the entire weekend, September 20 - 21.

The MBTA will accomplish vital upgrade and improvement work on the Blue Line drainage system and pump room, which protects the line from major rain and flooding events. Additional track maintenance activities will also take place, including upgrades to tunnel lighting, the overhead catenary wire system, and power cables. Signal personnel will also perform cable renewal work with track personnel replacing rail ties as needed. This work will improve the resiliency of the Blue Line's infrastructure, making the line safer and more reliable.

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

• There will be three free and accessible shuttle bus options during this service change: a local shuttle, an express shuttle, and a downtown loop.
  
  • Riders should note that the local and express shuttle bus options will not stop at downtown Blue Line stations and will instead stop at Haymarket for Orange and Green Line connections in the downtown area.
    
    • Operating the alternate shuttle bus options in this way saves over 15 minutes of travel time compared to if shuttle buses were to navigate through downtown Boston's crowded streets in mixed traffic to stop at all affected Blue Line stations.
      
  • Local Shuttle: Shuttle buses will make stops at Airport, Maverick, and Haymarket for Orange and Green Line connections in the downtown area.
    
    • The local shuttle will not stop at Aquarium, State, Government Center, or Bowdoin.
      
  • Express Shuttle: Shuttle buses will operate directly between Airport and Haymarket for Orange and Green Line connections in the downtown area with no stops in between.
    
  • Downtown Loop: One shuttle bus will operate in a loop from Haymarket to Aquarium to State to Government Center.
    
• Fare gates will be open for free entry on the Blue Line between Airport and Wonderland.
  
• Riders may also use the East Boston Ferry, which will be free during this service change with trips departing every 30 minutes from 6 AM to 10 PM.
  
• Riders using the shuttles buses should budget ample extra travel time. For example, a rider travelling to Government Center from Wonderland should budget at least an additional 30 - 40 minutes of travel in additional to their regular commute.

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.
