Claim:
An Energy Storage Bridge, comprising: a plurality of bridge girders, comprising: a plurality of steel pipes, which is adapted to be used as load carrying structural members for the bridge dead load and live loads comprising vehicle loads; and a plurality of web plates; a bridge deck, which is on the top of the bridge girders; wherein the steel pipes are assembled either in a single row or in multiple rows in the structural depth direction to form the girder together with the web plate welded between the two halves of the pipe; the bridge girder forms an energy storage unit between two consecutive movement joints of the bridge, and two consecutive storage units are joined by high pressure flexible pipe to form a giant energy storage unit; the energy storage unit is provided with inlet and outlet pipes to in-take compressed air from electric compressors driven by the grid power or by regenerated powers, and to release the compressed air to generate electricity; the bridge girders are at suitable transverse spacing across the width of the bridge deck supporting a concrete slab or a steel deck as the roadway surface; and the energy storage bridge is adapted to carry vehicle loads and store energy inside the bridge structural body in a form of compressed air contained in the number of steel pipes.
