This is a bridge 2D Drawing CAD File . It is an interesting project that will inspire its designer . It has more than 1 idea . The bridge is movable in its directions X and Y ( Elevation ) .The Bridge is consisting of a concrete dick that is supported on 2D Trusses for deflection from above and swing piers from under it . The swing pier is rotating around itself to touch the other pier and locking the passing of water . It is working as a hydraulic regulator . There are two sides and path of water and ships ( small Ships and boats ) in the middle . To lock this middle we have to use two large swing pier that will be rotating and lifted by the above trussed bridge and this is going to be lifted by a strong gate and truss lifting structure . Use materials concrete and steel .
