Why it's listed

Spanning a sandstone gorge about 50 feet deep on the Hocking River, this small covered bridge carries County Road 41 at Rock Mill in Fairfield County, Ohio. It is a single-span Queenpost truss, roughly 36 feet long and 15 feet wide, with low vertical-board siding, roofed windows along both sides, projecting portals, a shingle roof and cut stone abutments. Painted white, it has changed little in appearance, though the county added steel I-beams and concrete pillars. The original nomination dates it to 1849, while later research says Jacob R. Brandt built the present bridge in 1901 for $575, replacing an earlier covered structure. It takes its name from the nearby Rock Mill, built in 1824, and the two form one of only two mill and covered bridge pairings left in Ohio. It is the oldest and shortest covered bridge in the county and a frequently photographed landmark, featured on a 1965 tourism poster.

Significance in brief: The bridge and the neighboring Rock Mill are one of only two surviving mill and covered bridge combinations in Ohio. It is described as the oldest and shortest of Fairfield County's covered bridges and one of the state's most photographed. It was featured on a 1965 tourism poster.

What listing means for this property

For a publicly owned building or structure, listing mainly matters when federal funds, permits or licences are involved: projects then go through Section 106 review so effects on the property are considered. Listing also strengthens applications for preservation grants and, for leased income-producing uses, can enable the federal rehabilitation tax credit.
