MBTA seeks contractors for Green Line Extension Project

Massachusetts Bay Transportation Authority (MBTA) has announced it is seeking letters of interest from contractors for the design and construction of the Green Line Extension in Boston, USA.

MBTA has begun the process of engaging with potential bidders for the 7.6km extension of Boston’s Green Line which once complete will extend from the current termini at Cambridge to Somerville and Medford.

Green Line Extension Project includes construction of two branches

The US$1 billion contract includes the design and construction of two distinct branches that will serve as an extension to the Green Line: a “mainline” branch which will operate within the existing right-of-way of the Lowell Line, beginning just south of a relocated Lechmere Station in Cambridge and traveling north to Medford, and a branch line operating within the existing right-of-way of the Fitchburg Line to Union Square in Somerville.

In addition, seven new stations will be built as part of the project – including the relocated Lechmere Station – as well as associated electrical and signal systems. A vehicle storage and maintenance facility will also be constructed.

The Federal Transit Administration has agreed US $996m in funding for the project which will total approximately US$2.3bn.
