The panels on the trackside walls consist of white square ceramic tiles. A frieze with multicolored geometric patterns runs atop the trackside walls, with a square mosaic tile placed inside the frieze at intervals of three panels. A band of narrow green tiles runs along the left and right edges of each white-tiled panel, as well as below the frieze and mosaic tiles. The mosaic tiles, by Jay Van Everen, are part of a work entitled "The junction of Broadway and Bowery Road, 1828", a reference to the two streets that intersected at Union Square. In 2005, an artwork called "City Glow" by Chiho Aoshima was installed here.
