Also see . . . Pratt Truss bridge. Since its introduction in 1844, this bridge design became part of hundreds of bridges created up to Second World War. It was designed by the Thomas Willis Pratt (1812 1875) and his father Caleb Pratt, a pair of American engineers, just several years after William Howe patented his famous Howe truss design. This bridge design immediately became widely used during the period when many bridges moved from wood components toward all-steel construction designs. Its most compelling feature was the ability was to span great distances using simple construction methods. It was regularly used to span anchor points that are up to 250 feet (76 meters) apart. It was most commonly used in railroad bridge construction, although it was also a preferred choice for creating other types of bridges all around the world until early 20th century.
