It consists of concentric oval rings arranged as streets, with the namesake Plaza Street comprising the outer ring. The inner ring is arranged as an ovoid roadway that carries the main street – Flatbush Avenue – with eight radial roads connecting Vanderbilt Avenue; Butler Place; two separate sections of Saint John's Place; Lincoln Place; Eastern Parkway; Prospect Park West; Union Street; and Berkeley Place. The only streets that penetrate to the inner ring are Flatbush Avenue, Vanderbilt Avenue, Prospect Park West, Eastern Parkway, and Union Street. ()
