The Orange Line is about to shut down for 11 days. Here's what to know.

MBTA says Orange Line service will pause for 11 days between Oak Grove and Back Bay from Aug. 20 to Aug. 30 to support track and signal upgrades. The shutdown follows another major change: Green Line service reductions scheduled Aug. 8 to Aug. 16. During the Orange Line suspension, riders can use free, accessible shuttle buses running between Oak Grove and North Station, plus express options at Oak Grove, Malden Center, Wellington, and North Station. Fare-free Commuter Rail service will also run between Oak Grove and North Station via the Haverhill Line, stopping at Malden Center. Downtown commuters are directed to parallel Green Line service between North Station and Copley. MBTA maintenance includes rail component replacement, tie work, tamping, and signal rack relocations at multiple stations, with updates via T-Alerts and the agency’s X account.
