Lincoln Center’s plaza is to get a makeover, even if the changes seem more like tweaks than a redo. “In addition to a slightly modified fountain, the designs call for a new grand staircase stretching over an underground drop-off point for cars. Currently people heading to a Lincoln Center performance from the east side of Broadway must cross 11 lanes of traffic just to reach the sidewalk, then ascend a short staircase and traverse two lanes of cars dropping people off. Taxis must stop for crossing pedestrians, creating a line of cars and congestion at curtain time.”
