Greenbush Railroad Restoration

Greenbush Railroad Restoration

Out of use since 1959, the 18-mile Greenbush Old Colony Railroad was a wasted opportunity for the MBTA. Carefully working around suburban neighborhoods, wetlands and a popular downtown area, Balfour Beatty restored the alignment for commuter use and built seven new stations to support it.

Alternative Delivery, Design-build

The Greenbush project was the MBTA’s first large-scale use of the design-build delivery method. The alignment of the project passed through suburban neighborhoods, active downtown areas and sensitive environmental areas on a very narrow right-of-way.

The project scope consisted of the restoration and reconstruction of the largely out-of-service railroad right-of-way and included the implementation of seven new stations (each with an 800-foot-long high-level platform), a new signal and communication system and a layover facility at the end of the line in Greenbush, Massachusetts. The scope also called for a modified shallow cut tunnel at Weymouth Landing, which involved a complicated vertical alignment, an 800-foot cut-and-cover tunnel through Hingham Square with 900-foot boat section approaches on each side and freight facilities in Braintree, which are relocated off-line.

The project was awarded the American Road and Transportation Builders Association (ARBTA) 2006 “PRIDE” First Place Private Sector Award for this most successful community outreach effort.
