Green Line Extension Closure Postponed Amid Sumner Tunnel Shutdown

SOMERVILLE, MA — The MBTA announced Wednesday that a planned closure to allow for repair work on the Squires Bridge will be postponed until September.

The 42-day closure was scheduled to take place from July 18 to Aug. 18 between Lechmere and Union Square Station. According to transit officials, crews inspected the bridge over the weekend and decided to delay repairs so the closure does not occur at the same time as the Sumner Tunnel closure.

The Squires Bridge crosses over tracks near Union Square Station in Somerville, so repairs are not necessary on the Green Line itself.

An exact date for the Green Line Extension closure has not yet been announced.

Other Green Line service changes scheduled for the summer will go on as planned. The following changes will take place the weekend of July 15 to 16 to allow for comprehensive inspections of the unground portions of the Green Line tunnel:

• On the B Branch, trolley service will be suspended between Boston University East and Haymarket Stations. Shuttle buses will provide service between Boston University East and Back Bay Station on the Orange Line.
• On the C Branch, trolley service will be suspended between Saint Mary’s Street and Haymarket Stations. Shuttle buses will provide service between St. Mary’s Street and Back Bay Station on the Orange Line.
• On the D Branch, trolley service will be suspended between Fenway and North Stations. Riders should travel one block to Beacon Street at Park Drive in order to board the C branch shuttle for service to Back Bay Station on the Orange Line.
• On the E Branch, trolley service will be suspended between Heath Street and North Stations. Riders areencouraged to utilize Route 39 bus service.

Shuttle buses will also replace the entire Green Line B Branch between Kenmore and Boston College Stations from July 17 to 28 to allow for track upgrades.

In addition, due to the continued demolition of the Government Center Garage, the following Orange and Green Line service changes will take place in the downtown Boston area from July 29 to Aug. 9:

• Orange Line trains will bypass Haymarket Station. Orange Line riders should exit at North Station or State.
• Green Line service will be suspended between North Station and Government Center Station. Riders should walk above ground between Government Center, Haymarket, and North Station.
• Orange and Green Line connections can also be made via the Winter Street Concourse, which connects Park Street and Downtown Crossing Stations.
