The T will run shuttle buses to replace Orange Line service between Oak Grove and North Station this this week, through Friday Nov. 1.
The Orange Line will have regular service between Forest Hills and North Station, but bus shuttles will replace subway service to stations between North Station to Oak Grove.
The MBTA encourages riders to use the commuter rail for fare-free service between Oak Grove, Malden Center, and North Station.
Additionally, shuttle buses and accessible vans will connect closed Orange Line stations in Charlestown, Somerville, Medford, and Malden.
After a 10-day closure on the southern end of the Orange Line last week, only 9 slow zones remain on the line, and all of them are located north of the Assembly station in Medford and Malden. The MBTA expects to address all of those remaining slow zones on the Orange Line during this week's closure.
