It is 100 feet overall with a 25-foot main span.","why_significant":"The nomination argues the bridge is an unusual early twentieth-century stone bridge of high quality design and construction. It is similar in style and materials to two other nearby stone arch bridges, and the three are described as the few stone arch bridges with brick arch rings in the group. Its overall form and configuration are said to resemble nineteenth-century highway bridges.","narrative":"Built in 1904 by the local contracting firm P.J. McCormick & Sons, Brower's Bridge carries Mansion Road across a branch of French Creek in rural Warwick Township, Chester County. The single arch spans 25 feet, and the bridge is 100 feet long overall. Its masonry is coursed rubble stone, with brick arch rings, a brick intrados four rows thick, and contrasting parapet coping. Its wingwalls are skewed, and its parapet is capped with slate. The bridge is one of three similar stone arch bridges in the surveyed group that use brick arch rings. Its design and workmanship are regarded as high in quality, and its overall form recalls nineteenth-century highway bridges. The bridge is significant in the area of engineering. It sits beside a stone farmhouse and outbuildings, and it remains a vehicular crossing.","period_of_significance":"1904","architect_builder":"P.J.
