Significance: Flintville Bridge is a representative example of an early twentieth-century riveted steel Pratt-type through-truss bridge with plat girder deck approach spans. It replaced a covered bridge inundated by the construction of the Conowingo Dam across the Susquehanna River in 1927. The two truss spans of the Flintville Bridge were salvaged from the former Conowingo Bridge, built in 1909 (U.S. Route 1) across the Susquehanna, prior to its inundation. Route 1 was relocated to run across the top of the dam.
