This document is the National Historic Landmark (NHL) nomination for the Eldean Bridge in the vicinity of Troy, Miami County, Ohio. The NHL nomination for the Davis-Ferris Organ documents its national significance under NHL Criterion 4. Built in 1860, Eldean Bridge is a rare, intact example of the Long truss, a highly significant nineteenth-century timber bridge type. Patented by U.S. Army engineer Stephen H. Long in 1830, the Long truss was the first American truss type based on engineering analysis rather than empirical design methods, and it pioneered the concept of prestressing. The period of national significance is 1860.
