The interactive subway diagram that was designed by Massimo Vignelli, Beatriz Cifuentes and Yoshiki Waterhouse for The Weekender Web site of the M.T.A. offers riders information — driven and updated by live data — on planned weekend work projects that will affect subway service. At any point, the diagram can be clicked, zoomed, panned or expanded to full screen. In this screen, the B and 5 lines are shaded to indicate a weekend service interruption. (Image via NYT)
