According to the present invention, since electric or communication wires installed in a bridge are not arranged or are entangled, communication malfunction occurs and workers are confused about the wires. In particular, the present invention provides a safety structure for a conduit of electric and communication wires installed in a bridge, to protect the bridge from a fire spreading along the electric and communication wires during a lightning strike or when a fire occurs. According to the present invention, a worker can clearly distinguish the wires, and particularly, a fire generated in the wires is effectively blocked to prevent spreading. The safety structure comprises an upper conduit box and a lower conduit box. |
