Gate Tower Building With a Highway Through it : EXTREME ENGINEERING!!
One of the most curious building in Japan is the Gate Tower Building in Osaka, Japan. The 5th, 6th and 7th floors of this 16-story office building is occupied by an express highway - passing right through the building. On the building's floor information board on the ground floor, the tenants for the three floors are listed as the Hanshin Expressway. You can’t alight there tough as the elevator skips from the 4th floor to straight to the 8th.
