Clarkton Bridge
Clarkton Bridge was a historic Pratt truss bridge located over the Staunton River The Roanoke River ( ) runs long through southern Virginia and northeastern North Carolina in the United States. A major river of the southeastern United States, it drains a largely rural area of the coastal plain from the eastern edge of the App ... near Nathalie, in Charlotte County, Virginia. It was built in 1902 by the Virginia Bridge & Iron Co., and was the only remaining metal truss structure in Virginia built for highway purposes, which was supported by steel cylinder piers. It consisted of two camelback, pin-connected steel through truss channel spans, and twelve steel deck beam approach spans. The overall dimensions of the bridge approach and truss spans were as follows: north approach, with twelve deck spans; north truss, ; south truss, . The total length of the bridge was . an''Accompanying two photos''/ref> The bridge was listed on the National Register of Historic Places in 2006. ...

Pratt Truss
A truss bridge is a bridge whose load-bearing superstructure is composed of a truss, a structure of connected elements, usually forming triangular units. The connected elements (typically straight) may be stressed from tension, compression, or sometimes both in response to dynamic loads. The basic types of truss bridges shown in this article have simple designs which could be easily analyzed by 19th and early 20th-century engineers. A truss bridge is economical to construct because it uses materials efficiently. Design The nature of a truss allows the analysis of its structure using a few assumptions and the application of Newton's laws of motion according to the branch of physics known as statics. For purposes of analysis, trusses are assumed to be pin jointed where the straight components meet, meaning that taken alone, every joint on the structure is functionally considered to be a flexible joint as opposed to a rigid joint with strength to maintain its own shape, and th ...
