Golden Hill Road over the Housatonic River, Lee, MA. Located in the Berkshire Mountains of western Massachusetts, the Golden Hill Road Bridge over the Housatonic River Bridge is a 100-foot-long single-span structure supported on reinforced concrete abutments. The project consisted of replacing the existing superstructure with a prefabricated steel camel back truss system supporting a reinforced concrete deck; installing three-bar steel bridge railings, reinforced concrete abutments and wing walls; and installing riprap erosion control in front of the abutments and wing walls. MassDOT created a special program devoted to the replacement of these remote and forgotten structures. The program emphasized the use of prefabricated components and reuse of existing components, when practical.
Main Street over the East Branch of the Housatonic River, Hinsdale, MA. The Main Street Bridge is a historically sensitive structure requiring a design approach achieving a balance between aesthetics and safety. The design required special attention to detail combining practical safety concerns with the historical and cultural needs of the community. GRA was successful in achieving this mix. The bridge is a 59-foot-long single-span structure supported on reinforced concrete abutments. The project consisted of replacing the existing superstructure with a pre-fabricated steel Warren Truss system supporting a reinforced concrete deck, installing a two-bar steel bridge railing and a decorative pedestrian railing, providing aesthetically accented reinforced concrete abutments and return walls, and installing riprap erosion control in front of the abutments.
McCauley Road over Hudson Brook, North Adams, MA. Located in the Natural Bridge State Park, this bridge was a demonstration project on the use of New England Red Maple in bridge construction under the Commonwealth of Massachusetts Wood-In-Transportation Initiative. The bridge superstructure is composed of glue-laminated New England Red Maple beams and deck. Because of the natural setting within a state park, GRA also selected a timber bridge railing system, constructed the return walls of stone masonry, and hid the concrete abutments within the return walls. The design and construction was supervised by a partnership between MassDOT and the Northeastern Lumber Manufactures Association (NELMA).
