181st Street station

181st Street is a temporarily closed station on the IRT Broadway–Seventh Avenue Line of the New York City Subway. Located at the intersection of St. Nicholas Avenue and 181st Street in Washington Heights, Manhattan, it was served by the 1 train at all times.

Built by the Interborough Rapid Transit Company , the station opened on May 30, 1906, as part of the first subway, although the line had opened two months earlier and trains were skipping the station. Due to the station's depth, the tunnel was blasted through the hillside; during the station's construction, a 300-ton boulder had killed 10 miners. The station's platforms were lengthened in 1948.
