Haupt's Improved Lattice Truss, North Carolina, Catawba County, Bunker Hill Covered Bridge (11,064f)
The improved Lattice Truss was developed by Brigadier General Herman Haupt (1817-1905) who was Chief of Military Railroads for the Union Army during the Civil War. A Philadelphia born civil and military engineer, author, professor, inventor, and industrialist, Haupt’s improved lattice truss bridge was a response to Ithiel Town’s 1820 and 1835 patents for the plank lattice timber truss. Haupt used the analytical methods he developed in the 1840s to design a more efficient lattice truss which consisted of web members positioned only at locations which required support. Redundant members were removed, resulting in the improved lattice truss as described in his book General Theory of Bridge Construction published in 1851. The Bunker Hill Covered Bridge is the only remaining example in wood of the Improved Lattice Truss by General Herman Haupt. The bridge is a designated National Cvil Engineering Landmark.
