The 72nd Street station was constructed for the Interborough Rapid Transit Company (IRT) as part of the city's first subway line, which was approved in 1900. Construction of the line segment that includes the 72nd Street station started on August 22 of the same year. The station opened on October 27, 1904, as one of the original 28 stations of the New York City Subway. The 72nd Street station's platforms were lengthened in 1960 as part of an improvement project along the Broadway–Seventh Avenue Line. The station was built with a single head house south of 72nd Street, which provided the only exit and entrance to the complex. In 2002, the station was renovated and a second head house was built north of 72nd Street.
