Mahanoy Creek Bridge
FROM THE 1996-2001 PENNSYLVANIA HISTORIC BRIDGE SURVEY:
The one span, 115' long, pin connected, Pratt thru truss bridge is dated 1910 in PennDOT's inspection file, but stylistically, it could date to ca. 1900. The fabricator is unknown. It is supported on ashlar abutments, and the trusses are traditionally composed. The verticals are toe-out channels with lacing and pin plates for the lower panel point connections. The portal brace is plain, and square lattice railings inside the truss lines remain. The bridge has no innovative or distinctive details, and it represents the standardization of details that dominates those examples built after about 1895. It is complete, but within the regional context, with over 120 metal truss bridges from ca. 1880 through the 1940s, this example does not stand out. It is not an early example of its type. Neither the bridge nor its setting are historically or technologically significant.
