The Green Line Extension (GLX) will extend the northern end of the Green Line from Lechmere to Union Square in Somerville and College Avenue in Medford.
GLX will provide service in areas that historically did not have access to fast and reliable public transit. By supporting an increased ridership of more than 50,000 trips per day, this project will significantly reduce vehicle emissions on the road.
What to Expect During Construction
Green Line Service Changes
Since May 24, 2020, Green Line service has been shut down at Lechmere and Science Park stations for approximately one year while crews work on the Lechmere Viaduct Rehabilitation in conjunction with Green Line Extension work.
During this time, dedicated inbound and outbound bus lanes along Charles River Dam Road work to connect Lechmere and North Station, providing continued service for 14,000 Green Line riders.
Commuter Rail Service Changes
Through November 2020, weekend Commuter Rail service will shut down along various portions of the Lowell Line to support this work. Shuttles will replace trains during this time.
Work is being done near major bridges in Somerville. Impacts include bridge closures and some detours:
|Washington Street Bridge/Underpass||Open||Reopened May 31, 2020.|
|Broadway Bridge||Open||Reopened June 6, 2020.|
|Medford Street Bridge||Closed||Work is ongoing. Expected to reopen in spring 2021.|
|School Street Bridge||Closed||Work is ongoing. Expected to reopen in spring 2021.|

Challenged by unprecedentedly low ridership due to the COVID-19 pandemic, the MBTA is facing a historic moment.
In 2019, MBTA riders took 1.26 million daily trips. In October 2020, riders are taking around 330,000 daily trips—or 26% of daily ridership compared to 2019.
MBTA is making service changes to their lines and they want to hear from YOU.
“Reducing service is a difficult topic, we welcome your feedback on the proposed changes and how to prioritize adding back service.
