 Installed in conjunction with the 1962 opening of the lower level IRT express platforms, it allows transfer between all routes.There are three staircases up to the BMT platform, two down to each of the lower level IRT express platforms, and one staircase and escalator up to the IRT local platforms on the upper level.The mezzanine between the IRT express platforms and the BMT platform has a large-scale mosaic mural entitled "Blooming" (1996), by Elizabeth Murray.
