Completion

2005

As part of the renovations to the Massachusetts Bay Transportation Authority’s (MBTA) Bunker Hill Community College Orange Line Station, the contractor needed to install new slide bearings under an interior support for the multi-span trusses that form the primary structural support of the pedestrian bridge.  SGH developed a method to jack the two parallel bridge trusses upward to allow removal of the existing bearings and the installation of the new bearings.
