A New York architecture firm called Oiio has released conceptual designs for a building that would form a massive arch over Central Park and would be the "longest tower" in the world.
Renderings of the project show a pair of towers that rise to about 2,000 feet, then meet in an arch in the center, forming one continuous structure that would be 4,000 feet in length. It has been dubbed "The Big Bend."
