The steel-plate deck serves the usual deck function of distributing loads to main carrying members, but it also acts as the top flange of those members (Art. 11.20). Because the deck provides a large area, orthotropic-plate construction is

Box girders have several favorable characteristics that make their use desirable for spans of about 120 ft and up. Structural steel is employed at high efficiency, because a high percentage can be placed in wide flanges where the metal is very effective in resisting bending. Corrosion resistance is higher than in plate-girder and rolled-beam bridges. For, with more than half the steel surface
