The upper level that was built was Queens Boulevard, which carries traffic east and west. The second level is an underpass that carries four lanes of Union Turnpike (and now also the Jackie Robinson Parkway) under the Boulevard. The underpass is in between the two mezzanines and it would rest atop the roof of the subway station platform.
