At the most simple level of engineering design, bridges come in three basic forms: beam, arch, and suspension. Cable-stayed bridges tend to be more stable than traditional suspension bridges, and thus often do not have large stiffening trusses and girders. Bowstring (Parabolic): This form of truss typically has a curved top chord andis sometimes called an arch-truss as well. These terms are commonly used with truss bridges, and two of the terms are commonly used with arch and girder bridges as well. Bridge arrangements refer to the position of the deck (roadway) relative to the superstructure of the bridge. Some bridge types are further subdivided into a variety of configurations and superstructure arrangements. Also note that while the predominant material used in covered bridges is timber, iron was sometimes used in limited areas, (iron performed better than timber for tension members) and iron was sometimes used for connecting the timber members.
