The invention discloses safety monitoring equipment for a road and a bridge. The safety monitoring equipment comprises a supporting cylinder, a connecting shell, a base, a fixing cone, an electric push rod, a placing plate, a camera, a reinforcing rod, a supporting column, a placing shell, an image sensor, a processor, a controller, a buzzer, a cooling fan, cooling holes, a water inlet pipe, a water storage shell, a water suction pump, a fixing plate, a water mist spraying head, a water drainage pipe and a water pumping pipe. The safety monitoring equipment for the road and the bridge is simple in structure and novel in design, and the base is stably fixed conveniently; meanwhile, the height of the camera on the bottom side of the placing plate is adjusted conveniently, vehicles on the bridge are shot conveniently, the operation and the use are facilitated, the heat dissipation effect in the placing shell is improved under the action of an arranged stable monitoring mechanism, and thestable work of electric elements in the placing shell is facilitated; and meanwhile, the passing vehicles are reminded conveniently, the situation of the too many bridge vehicles is avoided, the operation and the use are facilitated, the practical value is high, and the safety monitoring equipment is suitable for the application and the popularization.
