the station, and to complete the connection to the Second Avenue Line. This renovation removed the walls on the platforms and opened new entrances on the Third Avenue side of the station. The tunnel boring machine being used to create the tunnels for the first phase of Second Avenue Line broke through the wall into the lower level of the BMT 63rd Street Line on September 22, 2011. On January 1, 2017, the first phase of the Second Avenue Line opened, extending the Q and N services under Central Park and eastward to the stop at Lexington Avenue–63rd Street before turning north at Second Avenue to merge with the Second Avenue Line. This created direct service between the Upper East Side and the existing BMT Broadway Line. The double-decked Lexington Avenue–63rd Street station provides cross-platform interchange between the two 63rd Street lines. Northbound trains use the lower level; southbound trains use the upper level. The third phase of Second Avenue Line construction, which is not funded , is proposed to include a separate connection between the IND 63rd Street Line and the Second Avenue Line, turning southwest from 63rd Street onto Second Avenue. This connection would allow trains coming from the IND Queens Boulevard Line to run on the Second Avenue Line to Midtown Manhattan and Lower Manhattan. However, the MTA does not plan to run passenger trains through this connection and it would be used only for movements by non-passenger trains, although passenger service could be possible if subway capacity in Queens is increased to accommodate extra service.
