Layton Bridge

The Layton Bridge is a Pratt truss bridge over the Youghiogheny River in Layton, Pennsylvania. Originally built for the Washington Run Railroad, construction began 1893 and was completed in 1899. The last train crossed in 1931. The bridge and a tunnel immediately to its south were converted to a single automobile lane in 1933 as part of a road that connects Layton with Perryopolis, near the suspected location of the eighteenth-century Spark's Fort.
