Who were truss bridges invented by?

Truss bridges were developed in the early 19th century, with significant contributions from various engineers. One of the earliest and most notable designs was created by the American engineer James B. Eads in the 1870s. However, the concept of using triangular trusses for construction can be traced back to earlier structures and various builders, so it is difficult to attribute the invention to a single individual. Overall, the evolution of truss bridges involved many innovations and refinements over time.
