Raise the level of play excitement with the interactive Smart Tech Lifting Bridge. Control the BRIO World traffic flow by turning the orange knob to raise the bridge for a passing ship or lower it for a passing train. This bridge also includes Smart Tech functionality - interacting with the Smart Tech Engine (not included) generating different play animations. If the bridge is raised, the engine will stop, honk its horn and flash its lights. When it’s lowered, it gets moving again and happily honks as it chugs across the bridge.
