Four layers of passages are arranged at the position of the bridge arches (2) and the auxiliary bridge arches (3) from the bottom up, in which the first layer is an underpass, the second layer (6) is a longitudinal left turn passage, the third layer (7) is transversal left turn passage, and the forth layer is a longitudinal straight going passage. The integrated steel structure fly-over bridge is composed by steel structure standard parts which can be assembled and constructed quickly.</p> |
