The original station, opened on February 25, 1908,[1] was modified slightly as a result of the building of the Sixth Avenue Line.

The southbound platform shares a mezzanine area with the IND Sixth Avenue Line's station at 14th Street, which the PATH station is located in between, but the northbound platform exits directly to the street.

The deep-bore tunnel's round shape becomes square below this station and at 23rd Street, where provisions exist for lower level platforms.

The entrances for New Jersey-bound PATH commuters are on the southwest and northwest corners of 6th Avenue and 14th Street.

The entrance for 33rd Street-bound PATH commuters is on the east side of 6th Avenue, midblock between 13th and 14th Streets.
