JapanGate Tower Building is a 16-story office building in, Osaka, Japan.  And what makes it notable is the highway that passes through the 5th-7th floors of this building.

The Gate Tower Building is Japan’s first building to have a highway pass through it.  And it had been nicknamed “beehive” referring to its appearance as a “bustling place”.

The expressway is the tenant of these floors.  The elevator doesn’t stop on floor 5th-7th, floor 4 being followed by floor 8.  These floors consist of elevators, stairways, machinery and other stuff.

The highway passes through the building as a bridge, held up by supports next to the building, making no contact with the building itself. 

The building has a double core construction, with a circular cross section and special care is taken by providing surrounded structure to the highway to protect the building

It dates back to 1983, when the redevelopment of this area was decided upon, “building permits were refused because the highway was already being planned to be built over this land. The property rights’ holders refused to give up, and negotiated with the Hanshin Expressway Corporation for approximately five years to reach the current solution.”
