MBTA Green Line Extension Project

Arora is part of the AECOM/HNTB joint venture team responsible for mechanical, electrical, plumbing, fire protection and fire alarm design development for the Green Line Extension Project’s advanced conceptual design.

An initiative of the Massachusetts Department of Transportation and the Massachusetts Bay Transportation Authority, the project will extend the existing Green Line service from a relocated Lechmere Station in East Cambridge to Union Square in Somerville, and College Avenue in Medford.

Design for the project includes seven stations, nearly five miles of Green Line double track, the relocation of four miles of double track commuter rail, eight bridges and a vehicle maintenance storage facility.
