BOSTON — Green Line riders will need to plan for alternative routes as service is suspended along several portions of the line for critical signal upgrades.
The MBTA says the suspension begins Saturday and will continue through Nov. 15.
There will be no Green Line service between North Station and Babcock Street, Cleveland Circle, Kenmore and Heath Street during the shutdown.
According to the MBTA, planned work includes:
- At Copley, crews will complete final signal system connections, including the installation of signals, junction boxes and track circuits, and begin system testing.
- Crews will install signal cable along the eastbound tracks between Park Street and Boylston, complete cable installation along the eastbound tracks between Park Street and Government Center, and finish signal cable installation within the Park Street track loop area.
- At Park Street, crews will continue work on signal system connections, including the installation of signals, junction boxes and track circuits.
- At Government Center, crews will install signal cable along all Green Line track areas within the station.
Riders will have to use shuttle buses to Copley and Back Bay. The MBTA is also encouraging riders to use the Orange Line between Back Bay and North Station.
Officials say riders should allow extra travel time, as trips using shuttle buses could take at least 25 minutes longer than usual.
The MBTA says the temporary service changes will allow crews to complete critical signal upgrades.
“The old signals currently in use are the same signals that were used when the first electric trolleys in North America were put into service in the late 1800s,” a spokesperson for the MBTA said. “This signal system is ready to be replaced with the upgraded, modern technology of today.”
According to the MBTA, once the project is complete, the new signal system will provide improved train detection, better congestion management and more consistent train spacing, laying the foundation for improved service frequency.
“These operational upgrades also mean more reliable service for riders with fewer unplanned disruptions and emergency repairs caused by the older, aging signal system,” the MBTA said.
The signal upgrades will also be compatible with the new Type 10 Green Line cars expected to enter passenger service next year and will help prepare the system for future generations of riders.
