Boston Picks New Contractor for $2B Green Line Extension

BOSTON, MA - The Massachusetts Bay Transportation Authority (MBTA) has selected a contractor for the reboot of the $2.2 billion Green Line light-rail extension in Boston, according to Construction Dive.

GLX Construction won the $1.08 billion bid for the design-build phase of the project. According to the agreement, GLX said it would add back in pieces of the project — part of a bike lane, elevators, a maintenance facility — that were eliminated as part of the MBTA's cost-cutting efforts.

The next round of bids is due in January 2018, which translates to a construction start date somewhere in late 2018 and completion in 2021. The Metropolitan Council is also expected to delay its application for almost $930 million in FTA grants to the second quarter of 2018.

The 4.7-mile Green Line extension is the biggest project in MBTA history and will add seven stations to the system between Cambridge and Medford.
