111th Street was one of the six stations along Liberty Avenue in Queens, from 80th Street through Ozone Park–Lefferts Boulevard, as well as the current three track elevated structure, built for the BMT Fulton Street Line in 1915 as part of BMT's portion of the Dual Contracts. The connection to the BMT was severed on April 26, 1956, and the IND was extended east (railroad south) from Euclid Avenue via a connecting tunnel and new intermediate station at Grant Avenue, with the new service beginning on April 29, 1956. The Fulton Street Elevated west of Hudson Street was closed, and eventually demolished.
