86th Street station (BMT Fourth Avenue Line)

The 86th Street 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.[8] 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.[9][10]

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.[9] 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 Degnon Construction Company for a combined $3.8 million (equivalent to $100.7 million in 2019).[9]

On January 24, 1913, construction began on Route 11B2, which includes this station and extends between 61st Street and 89th Street. Construction was completed on this section in 1915.[8] 86th Street opened on January 15, 1916, as part of an extension of the BMT Fourth Avenue Line from 59th Street to 86th Street.[3][11] The station was the original terminal for the line[12] until a one-stop southward extension to Bay Ridge–95th Street opened on October 25, 1925.[13]

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).[14][15] 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.[16] The NYCBOT received bids for the project on February 25, 1926.[17] 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).[18] The extensions opened on August 1, 1927.[19]

Location of platform extension at 1970 at the southern end of the station

In the 1960s, the New York City Transit Authority (NYCTA) started a project to lengthen station platforms on its lines in Southern Brooklyn to 615 feet (187 m) to accommodate 10-car trains.[20] On July 14, 1967, the NYCTA awarded a contract to conduct test borings at eleven stations on the Fourth Avenue Line, including Bay Ridge Avenue, to W. M. Walsh Corporation for $6,585 (equivalent to $50,492 in 2019) in preparation of the construction of platform extensions (equivalent to $50,492 in 2019).[21] The NYCTA issued an invitation for bids on the project to extend the platforms at stations along the Fourth Avenue Line between 45th Street station and Bay Ridge–95th Street, including this station, on May 3, 1968.[22]

However, work had already started on the platform extension project in February 1968. As part of the renovation project, the station's platform were extended 85 feet (26 m) to the south,[20][23][24] and the station's elaborate mosaic tile walls were removed. The latter change, which was also made to 15 other stations on the BMT Broadway and Fourth Avenue Line, was criticized for being dehumanizing. The NYCTA spokesman stated that the old tiles were in poor condition. Furthermore, it did not consider the old mosaics to have "any great artistic merit".[25]

In 2007, then-13th District Congressman Vito Fossella and 22nd District State Senator Marty Golden secured funding for an $13.8 million renovation, completed in 2011. The renovation repaired staircases, rebuilt the station's ventilation, and installed new tiling for walls and floors as well as ADA-compliant yellow safety treads along the platform edges. The platform walls were originally tiled, but removed during renovations in 1970. The modern renovation restored these tiles, and added an Arts for Transit glass mosaic inspired by the old homes of the Bay Ridge neighborhood.[26][27][28]

Plans call for the addition of two elevators, one from the mezzanine to the platform and the other from the mezzanine to the street, which would make the station fully compliant with accessibility guidelines under the Americans with Disabilities Act of 1990.[29] Construction on the elevators started in June 2018[30] and was expected to be completed by the end of May 2020.[31] However, because of the COVID-19 pandemic, completion was pushed back to July 2020.[32]

The station is built on the west side of Fourth Avenue due to plans for a possible extension of the express tracks south of 59th Street.[39] The platform is located between what would be the two southbound tracks as north of this station, the current southbound track swings out around the platform while the northbound one remains straight.[33] The additional two tracks would have been built on the eastern side of Fourth Avenue.[3][39][8] The four tracks were planned mainly to facilitate the Staten Island Tunnel, which would have necessitated express service, although the tunnel was never constructed.[40][41] In addition, there are large portions of the mezzanines that are now used for employees only.[39][42]

This station has two entrances/exits. The full-time one is at the south end. Two staircases from the platform go up to a mezzanine that has a turnstile bank and bodega within fare control.[43][44] Outside fare control, there is a token booth and two staircases going up to either southern corner of 86th Street and Fourth Avenue.[45][46]

The station's other fare control area is unstaffed. Two staircases from the platform, one of which is now closed,[47] go up to a mezzanine that has two High Entry/Exit Turnstiles and a single staircase going up to the southwest corner of 85th Street and Fourth Avenue. Both mezzanines have their original mosaic trim line.[26][48][49]
