It was built in 1911-1912 by Corcorn Construction Co.","why_significant":"The nomination argues the bridge is significant as a good example of nineteenth-century stone bridge construction carried into the twentieth century, reflecting a conscious decision to design in the historic tradition. It is also described as an important engineering achievement, being the longest stone arch bridge in the group of thirty-three multiple-span stone arch bridges nominated together.","narrative":"Seven-arch stone bridge crossing Township Road 52 in Chester County, Pennsylvania, built in 1911-1912 by Corcorn Construction Co. It is constructed of random rubble masonry, with conically shaped piers and a continuous parapet, features typical of nineteenth-century turnpike bridges. The bridge measures 400 feet long and 25 feet wide, with seven spans totaling 308 feet overall and 44 feet per main span. It stands in a semi-rural setting beside Lenape Park and the Lenape Amusement Park. It was listed for its engineering significance and as an example of the twentieth-century continuation of Pennsylvania's stone bridge tradition. It is regarded as the longest stone arch bridge among the thirty-three multiple-span stone arch bridges nominated as a group. Its voussoirs are a different color from the surrounding stone, and the creek does not pass beneath it.","period_of_significance":"1911-1912","architect_builder":"Corcorn Construction Co.
