Road Line continues straight under the Harlem River and merges with the IRT Lenox Avenue Line at 142nd Street Junction. Connection to unbuilt New York Central Railroad station There are some remaining signs on the walls that point to a never-built station of the New York Central Railroad lines, now part of Metro-North Railroad. The station had been approved in 1908 and would have been located at 149th Street and Park Avenue, one block east. As part of the project, the eastern ends of the White Plains Line platforms were extended to the east, underpinning both the New York Central line and the IRT Third Avenue Line. The western ends of the platforms were truncated in 1918 to allow the construction of the track connection to the Jerome Avenue Line.
