STV Celebrates Official Opening of Massachusetts Bay Transportation Authority’s Green Line Extension to Medford/Tufts

BOSTON – STV, a leader in engineering, architectural, planning, and program and construction management services joined the Massachusetts Bay Transportation Authority (MBTA) to celebrate the opening of the Green Line Extension (GLX) at the Medford/Tufts terminus. STV served as the lead designer for GLX, as part of the design-build team led by Fluor Corporation/Middlesex Corporation/Herzog Contracting Corp/Balfour Beatty joint venture – GLX Constructors.

The new, $2.3 billion extension to Medford adds five new stations to the Green Line, while the first portion of the project, the Green Line spur to Union Square, opened in March 2022. The entire joint venture included seven stations, six bridges, three substations, a viaduct with 50 spans, miles of retaining walls, and a community path with a pedestrian bridge, in addition to laying new rail.

The official opening of the extension to Medford, held at the Joyce Cummings Center at Tufts University, was attended by the Massachusetts Department of Transportation’s secretary, Jamey Tesler; the MBTA General Manager, Steve Poftak; as well as federal, state, and local officials; and community partners.

STV was represented at the event by Andrew Bradshaw, P.E. and deputy project manager; Sawis Cao, AIA and senior architect; David Gonsalves, engineering specialist; Madison King, P.E., associate and engineer; Michael Camoscio, P.E., LEED AP BD+, senior associate and senior engineer; and Preethi Sreeraj, P.E., LEED® AP BD+C, ENV SP, and engineering director; Nikola Nikolov, P.E., associate and senior engineer; Brian Skala, engineering specialist; and others who attended the ceremony. The official opening was also attended by the Massachusetts Department of Transportation’s secretary, Jamey Tesler; the MBTA General Manager, Steve Poftak; as well as federal, state, and local officials; and community partners.

“As a lifelong resident of Massachusetts, I’m proud to have been part of this project: bringing reliable public transit service to areas that were previously underserved, while increasing economic opportunities and environmental benefits to the community.”

The GLX is expected to reduce 26,000 vehicle miles travelled in the region daily, thereby improving air quality and reducing automobile congestion in the commonwealth. Daily ridership at the seven new GLX stations is expected to reach 45,000 by 2030.

In addition to GLX, STV has a long-standing history of serving passenger transportation systems in Massachusetts including the Greenbush Line Rail Restoration and the Silver Line Courthouse Station and Tunnel. Throughout Boston, the firm has worked on such iconic projects as the Longfellow Bridge Rehabilitation Design-Build, serving as lead designer, and the massive Central Artery/Tunnel (CA/T) or “Big Dig” project.
