Bridges are very important symbols of the nation. It is difficult for a structural engineer to determine the best section for a subway bridge (bridge with a longer span), such as single cell, double cell or rectangular trapezoidal shapes. Bridges are used to overcome obstacles without obstacles. Bridge design and analysis should be optimized regarding their weight and economy. The wide-span bridge box is cheaper than flat girder bridges. Double box bridges of different geometries are used for economic reasons and require less time for construction. Choosing the best shape geometry for a bridge box, reducing costs and stabilizing the structural section is a challenge for today's structural engineers. In light of the foregoing, it was decided to select different cell type geometry between two boxes of bridge cells and to develop the geometry by automatic CAD. It is observed that the economy of two-box bridges is based on various parameters such as the length of the bridge, the width, the angle of the double-box cone and the height of the double-box cone bridge. Selecting the best shape geometry of a bridge box and reduce cost and make section structural stable is challenging in front of structural engineer now a days. It is observed that the economy of two box cell bridges are based on different parameters such as length of bridge, width, angle of double Box taper and height of double box taper bridge. In this study, the form and shapes of two Boxes Cell Bridge are modified to study for economy and better structural stability.
