How are bridges classified?
Bridges are classified by 3 criteria: material, structure, and construction method. Materials include steel, reinforced concrete, and stone. Bridge structures often seen range from cable suspension bridges to simple arch bridges. Bridges built with the cantilever effect are usually suspension bridges, and are supported only on one side until completion, whereas bridges built via the incremental launch method are built pieces at a time, with regular supports to the ground at each segment.
