The large main waiting room, with its floral and Greek Revival motifs in tiled stained glass by Louis Comfort Tiffany set atop bands of pale cement, is generally considered one of the finest in the U.S. aesthetically. The terminal exterior extends to over four stories and has a distinguished copper-clad façade with ornate detailing. Its single-story base is constructed of rusticated Indiana limestone. A grand double stair with decorative cast-iron railings within the main waiting room provides an entrance to the upper-level ferry concourse.
