Passenger service began on the completed Green Line Extension route on Monday as crowds gathered to be among the first riders and to participate in this historic event.

Nearly 50 years in the making, the newly expanded transportation system is expected to enhance the lives of the many who will benefit from the service, as well as help in making the local environment significantly cleaner and safer for all.

The Opening Day Celebration at Ball Square Station began at 4:45 a.m., when the First Ride passenger service began.

The rush hour celebration at Ball Square Station was attended by Mayor Ballantyne, former Mayor Joseph Curtatone, State Representatives, advocates, and city staff, who greeted T riders and all interested T fans to celebrate the opening of the full Green Line Extension with a band and free opening day memorabilia.

Prior to the official opening, Somerville Mayor Katjana Ballantyne shared in a public statement, “We couldn’t be more excited to celebrate the beginning of full Green Line service in Somerville. Expanding public transit access is vital to creating a more equitable future, more jobs, cleaner air, and greater sustainability. Our transit advocates, our elected officials, and City, State, and MBTA staff all deserve immense gratitude for their tireless work to bring this historical public transit expansion to our area.”
