It was built to carry the Pennsylvania Canal across the creek as an aqueduct, and was later adapted for road traffic in the twentieth century. The bridge is constructed of red and white coursed ashlar with a belt course and a continuous parapet cap. Its arches are multi-centered, an unusual form that the form identifies as a distinctive feature. The overall span measures 72 feet, and the structure includes only its superstructure and substructure. The bridge is regarded as significant for the quality of its masonry, its high level of integrity, and its connection to the canal system, which carried freight and passengers along the Susquehanna River through the mid-nineteenth century. Its engineering interest lies in the arch design and stone construction.","period_of_significance":null,"architect_builder":"Pa.
