The complex consists of three stations, 8th Street on the Market–Frankford Line, 8th & Market on the Broad–Ridge Spur (also sporadically signed as "8th Street"), and 8th & Market on the PATCO Speedline. The complex consists of three underground levels, a mezzanine crossing the Market–Frankford tracks on the upper level, Market–Frankford trains running east–west and Broad–Ridge trains running north on the middle level, and PATCO running north–south on the lower level. Each platform has its own entrances/exits and fare control, but are connected via a mezzanine.
