Conestoga River Bridge

Street View 


FROM THE 1996-2001 PENNSYLVANIA HISTORIC BRIDGE SURVEY: The 3 span, 300'-long, reinforced concrete deck arch bridge built in 1930 is supported on concrete bullnose piers and abutments with wingwalls. The bridge has plain pilasters over the piers and at the abutment corners rising to form the posts of the standard-design concrete balustrades. An approximately 30'-long section of balustrade has been replaced with a solid concrete parapet (ca. 1990). The reinforced concrete arch bridge technology was introduced in Pennsylvania about 1900 and by the early 1910s it was ubiquitous. This later example designed by the state highway department has no unusual or distinctive details. It is not historically or technologically distinguished by its setting or context.
