A month shy of twenty years after construction began, the IND 63rd Street Line went into service on October 29, 1989, after an expenditure of $898 million, extending service from 57th Street with new stations at Lexington Avenue, Roosevelt Island, and 21st Street at 41st Avenue in Queens. The IND line was served by trains on weekdays and trains on weekends. The 1,500-foot connector to the Queens Boulevard Line had not yet started construction. The BMT line was not in use at that time. It was built for future service options, including a connection to the Second Avenue Subway for service from the Upper East Side to Lower Manhattan.
