truss bridges
Bridges that employ trusses, which are structural members comprising straight pieces of metal or timber forming a series of triangles lying in a single plane, thus making the structure unlikely to be distorted by stress. Wooden truss bridges, in the form of covered bridges, were common in the United States from the 1870s to the 1930s; carefully fitted timbers were combined with iron rods for tension. Later, railroad bridges and other bridges were constructed of cast iron and wrought iron, which were eventually succeeded by steel in truss bridges.

trusses (structural elements)
In engineering, structural members such as beams, bars, or rods, usually fabricated from straight pieces of metal or timber, that form a series of triangles lying in a single plane; based on the principle that a triangle cannot be easily distorted by stress. Trusses were probably first used in primitive lake dwellings during the early Bronze Age, about 2500 BCE. The first trusses were built of timber. The Greeks used trusses extensively in roofing; trusses were used for various construction purposes in the European Middle Ages. A major impetus to truss design came in the development of covered bridges in the United States in the early 19th century. Cast iron and wrought iron were succeeded by steel for railroad truss bridges. Trusses are also used extensively in machinery, such as cranes.
