Train service on parts of the MBTA’s Orange Line will be suspended during the last nine days of June for bridge work and track repairs.
Shuttle buses will run between Oak Grove and North Station for signal work this weekend, June 22 and 23. After that, trains will be canceled between Wellington and North Station from Monday, June 24, through Sunday, June 30, for repairs, MBTA officials said.
Riders can take the Haverhill Commuter Rail Line for free to and from Oak Grove, Malden Center, and North Station.
On June 10, the MBTA announced it had lifted 10 speed restrictions on the Orange Line after completing track work while train service was suspended between Wellington and Back Bay stations from May 28 through June 6.
Officials said that remaining speed restrictions between Community College and Sullivan Square would be addressed later this month.
In November, the MBTA announced a sweeping plan to shut down portions of the four subway lines over the following 14 months for repairs to eliminate slow zones. This spring, the Blue Line reopened with no slow zones caused by track defects after a 14-day shutdown of much of the line.
