Notes
Survey number HAER PA-215
Building/structure dates: 1913 initial construction
Significance: The single-span Brevard Bridge represents an unusual example of early reinforced concrete bridge construction and reflects a certain degree of experimentation with mechanical stress management. This was achieved, in part, by incorporating a longitudinal series of six corrugated iron arch reinforcements into the base of the bridge. Additional structural solidity was provided by seven parallel I-beam stringers and a series of perpendicular tie rods. The structure is an unusual example of the type of many small-scale bridges that were built throughout Pennsylvania and other states during the first half of the twentieth century to facilitate automotive transportation and the movement of goods and raw materials between rural and urban sectors. The construction of these bridges contributed to the integration of small rural communities like Export within the region's expanding economic system.
