From Public (Government) Sources to Producers: The total cost of the Green Line Extension (including $1B allocated to uses other than design and construction, i.e. real estate purchases, new Green Line trolleys, and money previously spent on the project prior to December 2017 is $2.3 Billion. A series of project simplifications, and a shortening of the Medford branch of the line from Route 16 back to College Ave allowed the project to be revived with support from the MBTA and the US DOT. Renamed the GLX project, the revised cost of initial design and construction of the GLX project is $1.08 Billion. The selected contractor is GLX Constructors (a consortium of Fluor Enterprises, the Middlesex Corporation, Herzog Contracting Corporation, and Balfour Beatty Construction). The bid price, with adjustments, was $1.08 Billion.
