An eastern mezzanine at Third Avenue, along with stairwells to the platforms, was partially completed in the 1980s but not opened along with the rest of the station. A shaftway, identical to the one on the Lexington Avenue side, contained a single stairway, as well as beams that may have been intended to support escalators. The stairway led up to an upper mezzanine whose street entrance was sealed off. This area was renovated as part of the Second Avenue Subway construction, and the shaftway was demolished. The new entrances constructed for the Second Avenue Subway added two new staircases, two new escalators, and five new elevators (one elevator from street level to mezzanine, and four elevators from the mezzanine to the platforms). , the new entrances, escalators, and elevators had been completed. The bank of four elevators leads from the Third Avenue mezzanine to both platform levels at the eastern ends of both platforms, replacing the originally planned escalators, as they use the space more effectively. On each platform level, both waiting areas have a piece of the Jean Shin artwork "Elevated." The Third Avenue entrance and mezzanine opened on December 30, 2016.
