Gate Tower Building 16-story office building in Fukushima-ku, Osaka, Japan. Most amazing fact about this building is a highway that passes through it.
The highway passes between the fifth and seventh floors of this building. The highway is the tenant of those floors. Another amazing fact about this structure is that the elevator passes through the floors without stopping: floor 4 being followed by floor 8.
The highway does not make contact with the building. It passes through as a bridge, held up by supports next to the building.
