It was built in 1896 by the Youngstown Bridge Company.","why_significant":"The nomination describes the bridge as a typical example of a Baltimore truss and one of only three representative examples of this type in the group nomination. It is described as a well preserved and fairly rare example of its type, with a bridge plate and simple decorative railing. The significance is placed in engineering.","narrative":"Built in 1896 by the Youngstown Bridge Company, this 200-foot pin-connected Baltimore through truss carries vehicle traffic across French Creek at Cambridge Springs in Crawford County, Pennsylvania. Its superstructure is steel, fabricated in Carnegie, Pennsylvania, and its wing walls are stone with concrete abutments. The bridge has a cantilevered sidewalk on its upstream side and a simple ornamented hand railing with a diamond pattern. Its truss members were reinforced in 1948 and its floor system in 1973, changes that the nomination treats as alterations. The nomination regards the bridge as a typical example of the Baltimore truss type, one of three representative examples included in the group nomination. It is considered well preserved and fairly rare for this type. Its listing rests on its engineering value as a representative surviving example of a Baltimore truss from the late nineteenth century.","period_of_significance":"1896","architect_builder":"Youngstown Bridge Company (builder/contractor)","architectural_style":"Baltimore truss","criteria":["C"],"status_note":"Altered: some truss members reinforced in 1948 and the floor system reinforced in 1973.
