It is served by the R train at all times. The Bay Ridge Avenue station was constructed as part of the Fourth Avenue Line, which was approved in 1905 and subsequently modified. Construction on the segment of the line that includes Bay Ridge Avenue started on January 24, 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 again in 1970. The station was also renovated during the 1970s and in 2017. History Construction and opening The Bay Ridge Avenue station was constructed as part of the Fourth Avenue Line. The plan for the line was initially adopted on June 1, 1905, before being approved by the Appellate Division of the Supreme Court of New York on June 18, 1906 after the Rapid Transit Commission was unable to get the necessary consents of property owners along the planned route. The Rapid Transit Commission was succeeded by the New York State Public Service Commission (PSC) on July 1, 1907, and the PSC approved the plan for the line in October and November 1907. As part of negotiations between New York City and the Brooklyn Rapid Transit Company (BRT), and the Interborough Rapid Transit Company for the expansion of the city's transit network, the line was leased to a subsidiary of the BRT. The agreement, known as Contract 4 of the Dual Contracts, was signed on March 19, 1913. In 1912, during the Dual System negotiations, the construction of an extension of the Fourth Avenue subway from 43rd Street to 89th Street, just south of the 86th Street station, was recommended. This recommendation was approved by the Board of Estimate on February 15, 1912. The PSC directed its chief engineer to create plans on June 14, 1912. The two contracts for the extension, Route 11B, were awarded on September 16, 1912, to the Degnon Construction Company for a combined $3.8 million (equivalent to $ million in ). On January 24, 1913, construction began on Route 11B2, which includes this station and extends between 61st Street and 89th Street. Construction
