This station opened on February 1, 1917, along with the rest of the Astoria Line, which was originally part of the
IRT, as a spur off the
IRT Queensboro Line, which is now the
IRT Flushing Line. Trains ran between
Grand Central and
Astoria. On July 23, 1917, the
Queensboro Bridge spur of the elevated
IRT Second Avenue Line opened. At that time, all elevated trains to
Queensboro Plaza used the Astoria Line while all subway trains used the IRT Flushing Line, though this was later changed with trains alternating between branches. This station started to be served by
BMT shuttles using elevated cars on April 8, 1923. The city government took over the BMT's operations on June 1, 1940, and the IRT's operations on June 12, 1940. On October 17, 1949, the Astoria Line became BMT-only as the tracks at Queensboro Plaza were consolidated and the platforms on the Astoria Line were shaved back to allow BMT trains to operate on it. Service was initially provided by the
Brighton Local (
BMT 1) and the
Broadway–Fourth Avenue Local (
BMT 2) at all times.
Station renovations leaving the station The platforms at this station, along with six others on the Astoria Line, were lengthened to to accommodate ten-car trains in 1950. The project cost $863,000. Signals on the line had to be modified to take the platform extensions into account. Under the 2015–2019
MTA Capital Plan, the station underwent a complete overhaul as part of the
Enhanced Station Initiative and was entirely closed for several months. Updates included cellular service, Wi-Fi, USB charging stations, interactive service advisories and maps. The award for Package 2 of the renovations, which covered renovations at the 30th Avenue,
Broadway,
36th Avenue, and
39th Avenue stations, was awarded on April 14, 2017, to
Skanska USA. This station, along with 36th Avenue, was closed entirely for around eight months starting on October 23, 2017. After the 30th Avenue and 36th Avenue stations closed, there was some controversy over the loss of business near these stations. The stations reopened on June 22, 2018. In July 2018, the MTA retroactively awarded a contract for the additional platform and girder repairs at the 30th and 36th Avenues stations, conducted after the stations had reopened. ==Station layout==
