Horton Mill Covered Bridge, Covered bridge in Oneonta, US.

Horton Mill Covered Bridge is a state-owned wooden covered bridge over the Calvert Prong of the Little Warrior River in Blount County, Alabama. Its Town Lattice truss runs in two spans, about 220 feet (67 m) long and 11.2 feet (3.4 m) wide, with a tin roof over the timber structure. It carries Horton Mill Road to Ebell Road and Covered Bridge Circle, roughly 5 miles (8 km) north of Oneonta off State Route 75.

The bridge was built in 1934 by Talmedge Horton and his crew, replacing an earlier 1894 structure that had stood roughly three-quarters of a mile downstream. It received listing on the National Register of Historic Places in 1970.

The bridge appears on the seal of the Blount-Oneonta Chamber of Commerce, and cameras were installed at Blount County's three remaining covered bridges in late 2015 after graffiti was found on the Easley bridge. The structure is maintained by the Alabama Historical Commission, the Blount County Commission and the Alabama Department of Transportation.

The bridge sits about 5 miles north of Oneonta along State Route 75 and is accessed via Horton Mill Road. A vehicle is the best way to reach this location, with straightforward access to the bridge itself.

The bridge appears on the seal of the Blount-Oneonta Chamber of Commerce. Its 70-foot clearance above the Calvert Prong makes it the highest covered bridge above any waterway in the United States, a figure often noted alongside its 1934 Town Lattice truss.
