So this is what happens when you have two stubborn parties come together. The Hanshin Expressway takes a shortcut through the 5th and 7th floors of the Fukushima Gate Tower; also known as the Bee Hive. Apparently back in 1992; when this conglomeration of road and building came together, the building owner wanted to tear down the old building and rebuild. However the city planners had already allocated that space for the expressway.
This is the agreement they came to when neither party wanted to change their plans.
