context_page_description: 86th Street is a station on the BMT Fourth Avenue Line of the New York City Subway, located at 86th Street and Fourth Avenue in Bay Ridge, Brooklyn. It is served by the R train at all times.
  The 86th Street station was constructed as part of the Fourth Avenue Line. Though it was originally planned to be a four-track express station with two island platforms, only the western platform and tracks were ultimately built. Construction on the segment of the line that includes 86th Street started in 1913, and was completed in 1915. The station opened on January 15, 1916, as part of an extension of the BMT Fourth Avenue Line from 59th Street to 86th Street. The station's platforms were lengthened in 1926–1927, and it was renovated in the 1970s and again in the late 2000s. The 86th Street station was renovated between 2018 and 2020, and elevators were added to make the station compliant with the Americans with Disabilities Act of 1990.
  The 86th Street station serves as a bus hub and terminal for several New York City Transit bus routes.
context_section_description: On June 27, 1922, the New York State Transit Commission directed its engineers to prepare plans to lengthen the platforms at 23 stations on the lines of the Brooklyn–Manhattan Transit Corporation (BMT), the successor to the BRT, to accommodate eight-car trains. As part of the project, Bay Ridge Avenue's platforms would have been lengthened from 495 feet (151 m) to 530 feet (160 m). Progress on the extensions did not occur until February 16, 1925, when the New York City Board of Transportation (NYCBOT) directed its engineers to prepare plans to lengthen the platforms at this and eleven other stations along the Fourth Avenue Line. It estimated the project's cost to be $633,000 (equivalent to $9,228,000 in 2019) (equivalent to $9,228,347 in 2019). The BMT had been ordered by the Transit Commission to lengthen these platforms since September 1923. The NYCBOT received bids for the project on February 25, 1926. The contract was awarded to Corson Construction Company for $345,021 (equivalent to $4,983,000 in 2019) (equivalent to $4,982,700 in 2019). The extensions opened on August 1, 1927.
