Common Types of Trusses Bridge Trusses In particular, the Pratt, Howe,and Warren trusses are normally used for spans up to 61 m in length. The most common form is the Warren truss with verticals. For larger spans, a truss with a polygonal upper cord, such as the Parker truss, is used for some savings in material.
