The triple whipple truss is a style of truss bridge that was used in the 19th century. In such a bridge, the diagonals are under tension. It was the first scientifically-designed truss bridge in the United States. They cross two neighboring verticals rather than connecting to it like a Pratt truss.[1][2]
The only remaining example of this style in the United States is the Laughery Creek Bridge in Indiana.
