Here are the MBTA’s planned service shutdowns for 2020 on all subway lines, commuter rail

“MBTA customers deserve better service faster, but the T can’t deliver on modernization without disruption, including weekday station shutdowns.”

The MBTA announced Thursday that it is accelerating planned infrastructure improvements in 2020, which will result in service disruptions and shutdowns on all the subway lines — including two separate one-month shutdowns on the Green Line — and the commuter rail. 

 The transit agency said the goal of accelerating the projects is to improve service, reliability, and safety on a “faster timeline,” delivering the work eight years ahead of the original schedule. 

“MBTA customers deserve better service faster, but the T can’t deliver on modernization without disruption, including weekday station shutdowns,” said Stephanie Pollack, transportation secretary and CEO of MassDOT. “During the shutdowns, we will help people get to where they are going on shuttles or other train lines. Most importantly, the temporary inconvenience will be worth it, delivering safer and more reliable service in months instead of years.”

The work ranges from track replacement to upgraded intersections and station improvements, the MBTA said in a statement. The disruptions also include an 11-month shutdown of Green Line service between North Station and Lechmere as part of the agency’s work on the Green Line Extension project.


“During diversions of regularly scheduled rail service, the MBTA takes steps to provide replacement service to ensure customers can reach their intended destinations,” the transit agency said. “In certain cases, the MBTA increases the frequency of parallel services to accommodate customers displaced by a diversion. In other cases, the MBTA provides accessible shuttle buses – operated by the MBTA or a private carrier – that are specially designed to account for passenger travel patterns during these diversions.” 

The MBTA has created a website with an interactive map for riders to track the upcoming work and service changes. Below, the planned service disruptions MBTA has scheduled in 2020.
