around the steel beams, and the concrete was poured into large timber formwork that was placed atop the wire mesh. Expansion joints were then placed at the bents of the steel structure; this allowed the steel beams to vibrate, expand, and contract while reducing concrete spalling. The station has two mezzanines at its western and eastern ends, directly above Brighton Beach Avenue and below the tracks and platforms. Between the mezzanines is a set of three groin vaults directly above Ocean Parkway. The trackbeds contain a waterproof layer of burlap, coated in coal tar. Both platforms have red canopies with black frames and "T"-shaped support columns along their entire length except for a section at their east (railroad north) end. Each canopy consists of a standing-seam metal roof. The undersides of each canopy contain lights and signs. East of the western mezzanine, there is a small electrical substation above the tracks. One staircase from each platform leads down to each mezzanine; the balustrades of these staircases are decorated with friezes and piers, similar to on the exterior of the viaduct. The 1996 artwork here is called Coney Island Reliefs by Deborah Masters. It was installed in 2009 and consists of 128 reliefs on the station's concrete structure. Between this station and Brighton Beach, two layup tracks begin at bumper blocks adjacent to the platforms and run between the local and express tracks. The two tracks merge with either adjacent track on approach to Brighton Beach. Exits This station has two sets of entrances and exits, one from each mezzanine. Each mezzanine has windows on all four sides; there are service rooms on the western side of the east mezzanine and on the eastern side of the west mezzanine. Both mezzanines were renovated in the 1990s. The full-time mezzanine is at the east end. The western wall of this mezzanine contains one concrete stair to each platform; between the two staircases are service areas, which originally functioned as restrooms. A turnstile bank divides the western and eastern halves of the mezzanine. The center of the mezzanine, beneath the express tracks, contains a low concrete ceiling supported by two square concrete columns; the northern and southern portions, beneath the platforms, contain a high ceiling with steel beams. Outside fare control, within the eastern half of the mezzanine, are a token booth and four staircases, two descending to either eastern corner of Brighton
