The bridge is desinged in the Unbalanced style, which means that there is actually only main pillar on Thon Buri side and another one pillar supporting the weight in bangkok’s side, therefore there are no pillars at all in the Chao Phraya River.The main pillar is made of reinforced concrete, and its’s function is to carry the other parts of the bridge. It is designed and follows the framework of a mental vision of Ruean Kaeo(Glass House).
