The initial segment of the IRT White Plains Road Line opened on November 26, 1904, between 180th Street–Bronx Park and Jackson Avenue.

In addition, it was announced that a flyover to the Dyre Avenue Line would be built, allowing for through-service, and eliminating the need to transfer at East 180th Street.

The final key element to the improvement plan was the elimination of the at-grade junction north of the West Farms Square station, which was a major bottleneck, by closing the spur to 180th Street–Bronx Park.

To make up for the loss of service, an escalator would be added at the West Farms Square station at 178th Street and Boston Road.
