# 170th Street station (IRT Jerome Avenue Line)

The 170th Street station is a local station on the IRT Jerome Avenue Line of the New York City Subway. Located at the intersection of 170th Street and Jerome Avenue in the Highbridge neighborhood of the Bronx, it is served by the 4 train at all times. This station was constructed by the Interborough Rapid Transit Company as part of the Dual Contracts and opened in 1917.

## History
### Construction and opening

The Dual Contracts, which were signed on March 19, 1913, were contracts for the construction and/or rehabilitation and operation of rapid transit lines in the City of New York. The contracts were "dual" in that they were signed between the city and two separate private companies (the Interborough Rapid Transit Company and the Brooklyn Rapid Transit Company), all working together to make the construction of the Dual Contracts possible. The Dual Contracts promised the construction of several lines in the Bronx. As part of Contract 3, the IRT agreed to build an elevated line along Jerome Avenue in the Bronx.
170th Street station opened as part of the initial section of the line to Kingsbridge Road on June 2, 1917. Service was initially operated as a shuttle between Kingsbridge Road and 149th Street. Through service to the IRT Lexington Avenue Line began on July 17, 1918. The line was completed with a final extension to Woodlawn on April 15, 1918. This section was initially served by shuttle service, with passengers transferring at 167th Street. The construction of the line encouraged development along Jerome Avenue, and led to the growth of the surrounding communities. The city government took over the IRT's operations on June 12, 1940.

### Station renovations

On July 5, 2004, this station, 176th Street, and Fordham Road closed for four months so they could be renovated. As part of the project, new canopy roofs, walls, lighting, staircases, floors, and a public address system would be installed at each station.
As part of the 2015–2019 Metropolitan Transportation Authority (MTA) Capital Program, elevators were installed at the original entrance between the street and the mezzanine, as well as between the mezzanine and the platforms. The elevators make the station fully compliant with accessibility guidelines under the Americans with Disabilities Act of 1990. Construction began in July 2020 and was completed in January 2022.

Inside the fare control area, it has two staircases to each platform at the center and a waiting area that allows a free transfer between directions.
