The arch bending on the top of the original main arch ring corresponds to every arch rib and the bottom beam on its landscape orientation. As a result it becomes a down arc frame similar to slab-and-beam floor system. On the arch bending and bottom beam just established, standing pillar, main beam, horizontal rib beam and bridge front-panel would be built subsequently. Both ends of the main beam would then be put off the new hat beam made of reinforced concrete. Now, it becomes an upper slab-and-beam floor system. Two decks will be joined together on the middle of the bridge, which forms the ability of spanning and loading.
