Significance: Boundary Channel Bridge is unique among the other bridges erected along the Mount Vernon Memorial Highway. It consists of seven reinforced concrete cantilever girders and two exterior girders of structural steel cantilever trusses encased in concrete. The cantilevered arms extend forty-two feet with the free ends supporting a sixteen foot suspended span. This bridge, built in a style to blend into the surrounding landscape, takes on the natural shape of the arch and is faced with native stone. The bridge becomes part of the landscape even more, with the careful attention to the landforms and plantings surrounding the bridge.
