Boston’s MBTA unveiled plans to accelerate infrastructure projects for several subway and commuter rail lines during calendar year 2020 to improve service, safety, and reliability on a faster timeline. The projects will include additional diversions of weekend service on all rapid transit lines and several commuter rail lines. In addition to several weekend diversions on the Green Line, the MBTA is planning for two one-month shutdowns on the Green Line — the C Branch in July and the E Branch in August.
