89th Street (IRT Third Avenue Line)

89th Street was a local station on the demolished IRT Third Avenue Line. It was originally built on December 9, 1878 and had two levels. The lower level, built first, was served by local trains and had two tracks and two side platforms. The upper level was built as part of the Dual Contracts, had one track that bypassed the station and served express trains. 89th Street station was the terminus of the IRT Third Avenue Line until it was expanded to 129th Street on December 30, 1878. This station closed on May 12, 1955, with the ending of all service on the Third Avenue El south of 149th Street. North of the station were connecting tracks to the 98th Street Yard.
