Mapping the T’s Summer 2023 Closures

Everything old is new again. The T is, once again, shuttering significant parts of its network this summer, in order to accommodate maintenance and construction. The Red Line is seeing a string of late evening closures, while the Green Line is seeing much longer shutdowns — including over 40 days of closure on the Union Square branch.

Naturally, I have made some maps.

(I didn’t want to sink too much time into this project, so the maps below are not free from imperfection.)

UPDATE: as of July 5, the Union Square branch closure has been postponed til September.

Phase 1: July 18 – July 28

During this period, the Union Sq shutdown will overlap with a bustitution of the B Line.

The T will apparently not be providing a shuttle for the Union Sq branch, instead directing riders to local bus routes with transfers at Lechmere and East Somerville. I’ve tried to illustrate those here. Alas, it is a bit cramped.

Phase 2: July 29 – August 9

Following the resumption of service on the B Line, a complete shutdown of service between North Station and Government Center will be instituted to accommodate demolition work on the Government Center Garage. It appears that no shuttle will be provided, and the T’s advice is simply to walk from one station to the other.

Phase 3: August 10 – August 28

During these two-and-a-half weeks, the core segment will be restored and the only ongoing long-term disruption will be the unshuttled closure of the Union Sq branch.
