The Union Square Branch opening of the Boston Green Line Extension (GLX) today, an expansion of the Massachusetts Bay Transportation Authority’s (MBTA) regional transit system, represents a critical achievement for the long-awaited project.
The first of two segments, the Union Square Branch comprises the new Union Square and Lechmere stations. The opening of the Medford Branch later this year will conclude development of this decades-long project, a major achievement for Boston in expanding its mass transit.
As the Design Professional for the GLX, Arup is supporting the MBTA with overseeing the design development, and testing and commissioning process of the 4.7-mile extension. Forecast to add 50,000 daily passenger trips to Boston’s transit network, the GLX will bring much-needed transit service to the Somerville, Cambridge, and Medford communities. The project will also put the city one step closer to meeting its 2050 goal of carbon neutrality by significantly reducing vehicle trips and associated air emissions.
