Final Day of Orange Line Shutdown and Northside Commuter Rail Diversions

Commute Overview for Sunday, March 8, 2026

Good morning, Boston. As we head into the second Sunday of March, commuters should first be aware that Daylight Savings Time has officially begun. If you have not yet adjusted your clocks, we have "sprung forward" one hour today, which may impact your early morning schedule and internal body clock. Today marks a critical day for transit maintenance, with major service diversions on the MBTA and heavy event traffic expected in the Seaport District.

MBTA Rail Service Suspensions

Transit riders will face considerable challenges today as the MBTA continues a series of infrastructure and signal upgrades. The following disruptions are in effect throughout the day:

• Orange Line: Service remains suspended between Back Bay and Forest Hills through the end of today, March 8. Free, accessible shuttle buses are operating between these stations, but travelers should budget at least an additional 30 minutes for their trip. Alternatively, the Commuter Rail is offering fare-free service between Forest Hills, Ruggles, Back Bay, and South Station for those looking for a faster connection.
• Northside Commuter Rail: Due to the North Station Terminal Area Signal System Improvement Project, service is suspended on the Fitchburg, Haverhill, Lowell, and Newburyport/Rockport lines. Inbound trains are terminating at outer stations, with shuttle buses or subway transfers required to reach North Station. Specifically, Fitchburg Line riders must transfer to the Red Line at Porter Square.
• Red Line: Expect minor delays and increased headways on the Braintree Branch after 8:00 PM tonight due to ongoing signal modernization work near JFK/UMass.

Road Conditions and Event Traffic

While surface traffic is generally lighter on Sundays, several factors will influence road conditions today:

• Seaport District Congestion: The final day of the Boston Wine Expo is expected to draw large crowds to the Seaport area. Expect heavy delays and high demand for parking on Seaport Boulevard and Congress Street throughout the afternoon.
• East Boston Activity: The annual Shamrock Splash at Constitution Beach is scheduled from 12:00 PM to 3:00 PM. While no major road closures are planned, expect increased pedestrian activity and limited parking near the beach area in East Boston.
• Local Bridge Closures: The Canterbury Street Bridge in Roslindale remains closed to all vehicular traffic. Motorists should follow the established detour via Hyde Park Avenue and Cummins Highway.
• Parking: Drivers are reminded that parking meters throughout the City of Boston are free with no time limit today, as it is Sunday.

Pro-Tips for Your Sunday Travel

If you are heading into the city, the MBTA recommends purchasing a round-trip ticket rather than a one-way fare to save time at stations experiencing high volume. For those attending events in the Seaport, public transit remains the most reliable option to avoid gridlock. Drivers should remain alert for work crews on Route 2 near Athol, where preparations for overnight bridge repairs starting Monday evening may cause minor shoulder restrictions today.
