Rock Mill Covered Bridge is a historic wooden bridge at Rock Mill in Bloom Township, Ohio, crossing a deep gorge of the Hocking River. Built as a single-span Queen Post truss, it preserves the character of a traditional covered road bridge in an especially dramatic natural setting. Its listing on the National Register of Historic Places in 1976 recognized both its historic significance and its architectural value. The bridge remains closely identified with Rock Mill, where the combination of the structure and the river gorge gives the site much of its distinctive appeal.
