The junction's location was set in 1871, when the LIRR's Rockaway Branch (now the Montauk Branch) was built, crossing the South Side Railroad of Long Island (now the Atlantic Branch). With the consolidation of the South Side into the LIRR system in 1876, all South Side passenger trains were rerouted to use the LIRR main line through Jamaica to Rockaway Junction and the LIRR's Rockaway Branch to this crossing, where a connecting track was built.
