The Massachusetts Bay Transportation Authority is set to suspend stops between Kenmore  and Boston College to implement several service changes from April 22 to April 30, according to a MBTA press release. 

The closures will allow for maintenance and infrastructure improvements across multiple MTBA lines.

Riders are expected to experience heavy delays, but the MBTA will provide free shuttles at closed stops and on the alternate routes for passengers. 

During the weekend of April 25-26, B line service will be suspended between Copley and Boston College and C line service between St. Mary’s and Copley. 

The Red Line will be affected as part of the Columbia Junction Signal Modernization project, which started in February of this year.

The service changes at the Commuter Rail are part of the North Station Terminal Area Signal System Improvement Project. Multiple stops on the Fitchburg, Haverhill, Lowell and Newburyport-Rockport lines rail will be suspended.  

Along the Boston College line, the MBTA will replace the 130-year-old wooden overhead catenary wire, improve outdated infrastructure and continue to install the Green Line Train Protection System, a structure set to avoid train-on-train collisions.
