Myrtle Avenue (announced on trains as Myrtle Avenue–Broadway) is a New York City Subway express station on the BMT Jamaica Line. Located at the intersection of Myrtle Avenue and Broadway in Brooklyn, it is served by the J train at all times, the M train at all times except late nights, and the Z during rush hours in peak direction. The station has two platform levels, but all regular passenger service is on the lower platform level of the station. The station has an abandoned upper platform level which previously served the BMT Myrtle Avenue Line to Downtown Brooklyn and Lower Manhattan via the Brooklyn Bridge. Just east of the station, the BMT Myrtle Avenue Line diverges from the BMT Jamaica Line via slip switches in an at-grade junction.
