East Bloomsburg Bridge, Spanning Susquehanna River at Pennsylvania Route 487 (Legislative Route 283), Bloomsburg, Columbia County, PA

Significance: The existing East Bloomsburg Bridge consists of six equal pin-connected through-truss spans of 190 foot length with two feet between end bearings at the piers for a total length of 1150 feet. The truss spans are of the "Pennsylvania" (Petit) type with 10 equal panels of 19 feet each. The truss members are made of steel and wrought iron, and the pins were made of steel. The significance of the structure is twofold; one, that it was constructed prior to 1900 and, two, that it was built by the King Bridge Company, one of the most important truss bridge manufacturing companies in the United States in the 19th century. The bridge also exhibits a high degree of its original integrity.
