Both platform walls have a Puce trim line with a black border, with a number of replacement tiles in different shades of violet and purple having been placed during repairs. There are also mosaic name tablets reading "NORTHERN BLVD." in white sans-serif lettering on a black background and Puce border. Small tile captions reading "N BLVD" in white lettering on black run below the trim line, and directional signs in the same style are present below some of the name tablets. Slate blue I-beam columns run along both platforms at regular intervals, alternating ones having the standard black station name plate with white lettering.
