Dodd's Creek Bridge is an 87-foot lenticular truss bridge, an unusual truss type in the United States characterized by curved top and bottom chords that form a lens shape. The only United States patent for a lenticular truss bridge was issued in 1878 to William O. Douglas of Connecticut, and most bridges of this kind were built in New England and New York state. Through the efforts of William Payson, a salesman for Douglas' Berlin Iron Bridge Company, Texas acquired at least a dozen truss bridges in the late 19th century. In 1889, the Coryell County Commissioners Court contracted with the Berlin Iron Bridge Company to build four lenticular truss bridges for $16,500. This bridge was first built across Cowhouse Creek and was later moved to Dodd's Creek. In 1990, the Texas Historical Commission and the Texas Department of Transportation identified eight surviving lenticular truss bridges in Texas, four in San Antonio and four on out-of-service roadways. As the only examples of this rare bridge type west of the Mississippi, they are recognized as historically significant engineering structures, and organizations including the Society for Industrial Archeology and the Historic American Engineering Record of the National Park Service have recognized them as products of a short-lived but important period in 19th-century bridge technology. In 1997, the Dodd's Creek bridge was moved to this site to improve traffic flow, protect pedestrians, and enhance the Salado Historic District.
