Catawissa Bridge, Spanning north branch of Susquehanna River, 3.5 miles south of Bloomsburg, Catawissa, Columbia County, PA
Summary
Significance: The existing Catawissa Bridge, built in 1898 by the Pennsylvania Bridge Company of Beaver Falls, Pennsylvania, consists of four (4) steel through-truss spans, each 304 feet long, for a total length of 1,225 feet. The engineering design of the bridge's modified Camel-back Warren type trusses is not unique in itself but it is significant because of the length of the four (4) trusses and the degree of technology demonstrated at the time of its design and construction. The Catawissa Bridge has one of the longest spans between piers of any Susquehanna River truss bridge remaining in the State of Pennsylvania.
