FROM THE 1996-2001 PENNSYLVANIA HISTORIC BRIDGE SURVEY: The single span, 114'-long, pin-connected, Pratt thru truss bridge built in 1887 is supported on stone abutments that have been repaired and coated with concrete. The top chords and verticals are patented Phoenix column sections, with eyebars and rods for the pin-connected tension members. Cast iron connecting pieces are used for the compression fitting Phoenix column section members. The floorbeams, stringers, and open steel grid deck were replaced ca. 1975, but the U-shaped hanger floorbeam connections were not changed. The bridge has portal bracing with decorative brackets and builders plaque. The bridge was fabricated by the Phoenix Bridge Co. of Phoenixville, PA, and erected by their agents Dean & Westbrook of New York. The company was instrumental in refining and popularizing metal truss bridge technology during the last half of the 19th century. The Phoenix column, patented in 1861, was one of the first successful attempts to substitute built-up wrought iron sections for cast iron for use with compression members. Truss bridges with Phoenix column members were used widely by railroads through the mid 1880s and for highway applications through the mid 1890s. It is mostly the later highway examples, such as this 1887 bridge, that have survived in small numbers in Pennsylvania. The bridge is historically and technologically distinguished.
