Constructed in 1860 as the Allen’s Mill Bridge, Eldean Bridge in Miami County, Ohio, is an excellent example of nineteenth-century covered bridge construction and its span is a rare surviving Long truss, a highly significant nineteenth-century timber truss type. Eldean Bridge is the most structurally intact of less than a dozen surviving Long truss covered bridges in the United States.
The Eldean Covered Bridge is the sixth covered bridge to be designated as a National Historic Landmark since 2012. It joins the Humpback Bridge (VA), Knight’s Ferry Bridge (CA), Duck Creek Aqueduct (IN), Brown Bridge (VT), and the Powder Works Bridge (CA) as “nationally significant historic properties of exceptional value to the nation.” Also receiving NHL status at the same time as Eldean is the West Union Bridge in Indiana (1876 Burr arch-truss).
Righter is proud of its role as General Contractor in restoring this important piece of American history!
