Discussion of Bridge
The single span, 50'-long reinforced concrete deck arch bridge is finished with concrete parapets with scored panels. The spandrel walls are plain save for scoring that accents the arch shape. The reinforced concrete deck arch bridge designed by the Berks County Engineer's Office was erected in 1907. The bridge is historically and technologically significant within the local context as a documented, early example of its type and design, which was used by Berks County with great frequency through the 1930s. It is one of 25 reinforced concrete deck arch bridges in the county dating from 1902 to 1936 and ranks as the second oldest extant example (criterion C). The use of reinforced concrete for closed spandrel arch bridges was introduced in this country about 1890. Although American engineers were familiar with a combination of concrete and reinforcing by about 1870, it took another 30 years of experimentation and theoretical and empirical investigations before engineers and builders had a mature understanding of the capabilities and versatility of the material. Once understood, the technology was quickly embraced, and by 1910, the elliptical-shaped, deck arch bridge, where the road is at or near the crown of the arch, was ubiquitous. Reinforced concrete arches offered an economical and relatively low maintenance alternative to steel truss bridges, and because of the moldable qualities of the material, the spandrel walls and railings could be architectonically detailed, frequently in the classical taste. The technology was immediately popular with some county and city engineers, and over 55 examples from before 1910 survive throughout the state. Over 200 examples from before 1916 survive, and 270 reinforced concrete closed spandrel arch bridges predate 1920. It is the early examples of the technology in the county like this one that represent its significance in the local and state context. The bridge is evaluated as individually significant. The significant boundary is the superstructure and substructure.
Discussion of Surrounding Area
The bridge carries a 2 lane road over a stream in a sparsely developed, rural area with scattered 20th-century residences and a waste water treatment plant. A railroad overpass is beyond the west side of the bridge. The area does not have historic district potential.
