It was built in 1905.","why_significant":"The nomination describes it as a well-preserved representative of Delaware County multi-span stone bridges, which typically share a semicircular arch form and intermediate length. Like two other nominated arch bridges in the county, it has decorative embellishment, including a carved keystone bearing the construction date, a belt course at the roadway, and upright stones capping the parapet. The listing record adds Engineering as an area of significance.","narrative":"Built in 1905 over Darby Creek on Goshen Road in Radnor Township, Delaware County, this stone bridge has three masonry arches: a main span of 45 feet flanked by two spans of 19 feet each. The overall length is 80 feet. Its designer is recorded as Theophilus P. Chandler, and the builder as J. A. Morris. Each arch is semicircular, built of coursed masonry with an ashlar parapet. The bridge is listed for its engineering and design, as a well-preserved example of the multi-span stone bridges common in Delaware County. Decorative details set it apart from ordinary crossings: a carved keystone records the construction date, a belt course runs along the roadway, and unfinished stones cap the parapet. Its surviving stonework has been supplemented by gunite and concrete repairs, which the form records as alterations. The nominated area covers only the bridge structure itself, about one acre or less.","period_of_significance":"1905","architect_builder":"Theophilus P. Chandler (designer/engineer); J. A.
