As part of a joint venture, Balfour Beatty is building the $1.1 billion Massachusetts Bay Transportation Area (MBTA) Green Line Extension (GLX) project in Boston, Mass. As it further enhances the travel experience for passengers and addresses a lack of reliable public transit service within historically underserved areas, the GLX represents the MBTA’s largest construction contract to date and supports municipal plans for sustainability along with urban redevelopment. It will increase access to education, housing and job opportunities across the entire MTBA system.
To provide passengers with added convenience, a direct line of travel and eliminate the need for bus transfers, construction features include:
- Development of a new Green Line branch on the existing Lowell Commuter Rail tracks, extending from Lechmere Station to College Avenue in Medford
- Development of a new Green Line branch on the existing Fitchburg Commuter Rail tracks, extending from Lechmere Station to Union Square in Somerville
- The relocation and reconstruction of Lechmere Station in Cambridge, plus six new additional T stations
- Development of a new vehicle storage and maintenance facility
By leveraging existing railroad rights-of-way for the extension and operation, the project reduces the need to purchase local property and minimizes any impacts from construction.
Upon completion in December 2021, the GLX will significantly reduce automobile congestion and related air emissions. It will provide communities with universal access and new stations that meet or exceed the Americans with Disabilities Act (ADA) standards. Overall, it is expected to support increased ridership of more than 50,000 passenger trips per day once completed and reduce regional daily Vehicle Miles Traveled (VMT) by 25,728 miles.
