Salt Creek Bridge, Spanning Big Salt Creek, bypassed section of Arch Hill Road (CR 82), Norwich, Muskingum County, OH

Significance: Salt Creek Bridge is the only surviving pure Warren truss covered bridge in the United States. Although the Warren truss, patented in 1848, was originally designed as a timber/iron truss, it did not become popular in American until after 1860 with its development in an all-metal version. By the late nineteenth century, it was one of the two most popular truss types for metal bridges, the Pratt truss being the other.
