On June 27, 1955, the Howard Beach station, along with all the rest of the Rockaway Beach Branch stations south of the now defunct Ozone Park station, was taken out of service for eight months for restructuring and upgrading of the tracks, so that they could accommodate subway service. During the project, the Howard Beach station, along with the Broad Channel and Far Rockaway stations, was completely rebuilt utilizing a modern design, which included a new overhead passageway between the two platforms. The design was created by architect J. Harold Sandifer, a native of the Rockaways. Many of the parts for the station were prefabricated, speeding construction. On June 28, 1956, the station reopened as a subway station along with the rest of the line. The previous Long Island Rail Road station at this location was razed. Inauguration ceremonies were held at the station as well as at Euclid Avenue in Brooklyn.
