Two branches of the MBTA Green Line will be shut down for a month each this summer, part of a major 2020 infrastructure acceleration plan announced by the transit agency and Massachusetts Gov. Charlie Baker Thursday.
The plan, touted by the MBTA as accelerating projects by eight years, marks the first time the agency will close entire services for weekdays. It will also bring eleven weekend outages to parts of the Red Line, seven to the Orange Line and 19 to the Blue Line.
The Franklin Commuter Rail line and Silver Line will see weekend diversions as well.

"After decades of neglect, we're busy investing over $8 billion to upgrade, modernize and increase capacity on the system," Baker said.
See the full list of disruptions released by the MBTA at the bottom of this story.
Baker and the MBTA said disruption will be minimized for riders, citing the similar diversion work that was done in 2019, which the MBTA says sped up work on the Red, Orange and Green lines by more than two years.
"We heard our riders in 2019: build a better T and do it faster," MBTA General Manager Steve Poftak said.
The work will replace 29 miles of track across the system and rebuild 11 intersections.
Green Line rider Samantha Miller said she isn't sure how she'll get to work during the shutdown.
"It's already a struggle as it it is, with delays," Miller said,
But other riders, like Greg Shea, said the short-term inconvenience is worth it, if it helps make the system better. Shea said the improvements are "way overdue," adding, "just do it."
To make it easier for MBTA riders to keep up with closures, the MBTA created a website and map that shows outlines the work being done. See it here.

- This work will be completed 180 days faster than previously planned.
On the Blue Line:
- Extended early access and nineteen weekend diversions between Bowdoin and Airport from May through October to replace up to 2,500 feet of track (0.5 mile), repair isolated cracked rail within tunnel areas, open tunnel niches to build new truck pads, perform tunnel leak repairs, remove inactive cables and ducts, and perform tunnel weather-proofing work.
