191st Street station

191st Street is a station on the IRT Broadway–Seventh Avenue Line of the New York City Subway. Located at the intersection of St. Nicholas Avenue and 191st Street in the Washington Heights section of Manhattan, it is served at all times by the 1 train. It is the deepest station in the New York City Subway system—about 173 feet below street level. Access to the station's main entrance is only provided by four elevators to the mezzanine. A pedestrian tunnel also extends west from the station 1,000 feet to Broadway, connecting it with the Fort George neighborhood.

Built by the Interborough Rapid Transit Company , the station opened on January 14, 1911, as an infill station along the first subway. Even though the line through the area had opened five years earlier, no station was constructed at this location because the surrounding neighborhood had a lower population than other areas of Manhattan. Before the opening of the pedestrian tunnel two years later, the area's hilly topography made it hard for area residents to access the station. The opening of the station and the tunnel led to the development of the surrounding area, including the construction of apartment buildings. Hundreds of lots held by the Bennett family since 1835 were sold at an auction in 1919. These provided additional housing opportunities for the middle class, taking advantage of the area's improved transportation access.
