Boston’s Orange Line will shut down for 11 consecutive days beginning August 20 for critical track and signal upgrades, marking the second major transit suspension this month across the MBTA’s subway system. Service will be suspended between Oak Grove and Back Bay stations through August 30, affecting commuters across Boston, Cambridge, and Somerville who rely on the heavily used line.
During the closure, crews will replace rail fasteners, rails, plates, and insulators between Tufts Medical Center and Haymarket. Between Haymarket and the Assembly truck pad, maintenance teams will replace ties, rails, and plates while conducting tamping work. Signal relocations will also take place at North Station, Community College, and Wellington to permanently install equipment within signal houses, with final signal completion work occurring between Oak Grove and Tufts Medical Center.
The MBTA explained that a multi-day suspension is the most efficient approach to this work. “This work cannot be performed during the overnight hours when the MBTA does not operate, and would be extremely inefficient and costly if planned during single weekend outages,” the agency stated. “Closing a section of the transit system for multiple days is the most efficient way to perform routine maintenance, revitalization efforts, inspections, and upgrade work.”
The agency will also complete platform upgrades, bridge inspections, deep cleans of stations, plumbing and drainage improvements, and radio installations during the shutdown to take advantage of easier line access. Free and accessible shuttle buses will operate between Oak Grove and North Station, with express service at Oak Grove, Malden Center, Wellington, and North Station. The MBTA warned that riders traveling to Downtown Crossing from Oak Grove should budget at least an additional 70 minutes of travel time beyond their regular commute.
Commuters have several alternatives during the shutdown. Fare-free Commuter Rail service will be available between Oak Grove and North Station via the Haverhill Line, which also stops at Malden Center. Downtown commuters are encouraged to use parallel Green Line service between North Station and Copley, which sits less than a quarter-mile from Back Bay. The MBTA will increase Green Line service during the suspension to accommodate Orange Line riders. Accessible vans will also be available at downtown Orange Line stations between Back Bay and North Station, as well as at Copley on the Green Line.
This suspension follows a nine-day Green Line shutdown from August 8 to August 16, during which the agency performed signal upgrade work within the central tunnel and accessibility improvements on the Green Line C Branch. The Orange Line closure comes as part of the MBTA’s ongoing effort to modernize and improve system reliability across its rapid transit network.
