Green Line Extension Project

The Green Line Extension is a top transportation priority of the Commonwealth. It offers a number of benefits:
  • A one-seat ride from the project corridor to downtown Boston, (eliminating the need for bus and rail transfers at Lechmere Station and at Orange and Red Line stations) improving travel times within the project corridor.
  • A projected reduction in regional daily Vehicle Miles Traveled by 25,728 miles, improving air quality and reducing automobile congestion.
  • Daily ridership (boardings and alightings) at the seven Green Line Extension stations of approximately 45,000 by 2030. The majority of those trips will be made beginning in the first year of service on the Green Line Extension.
  • A commitment to universal access, with new stations that will meet or exceed the Americans with Disabilities Act (ADA) standards.
  • Operation in existing railroad rights-of-way, reducing the need to purchase local property and minimizing construction impacts.
  • Mitigation measures that will reduce existing noise and vibration impacts from area railroads.
