of residential, business and leisure space within walking distance of public transport. With this announcements, more suggestions for what to do with the island were made. The construction of a station was viewed to be vital for the development of the island, which was still known as Welfare Island. At that point, it was decided to build a shell for the station, to allow for the station to open after the opening of the rest of the line, with a projected savings of $4 million compared to building the station as an infill station after the rest of the line opened. The projected cost of the station was $3.3 million. It was soon decided to build the station with the rest of the line. The current 63rd Street Line was the final version of proposals for a northern midtown tunnel from the IND Queens Boulevard Line to the Second and Sixth Avenue lines, which date back to the IND Second System of the 1920s and 1930s. The current plans were drawn up in the 1960s under the MTA's Program For Action, where the 63rd Street subway line was to be built in the upper portion of the bi-level 63rd Street Tunnel. Beginning in the mid-1970s, Roosevelt Island was redeveloped to accommodate low- to mid-income housing projects. However, there was no direct transit connection to Manhattan. The subway was delayed and still under construction; trolley tracks that formerly served Roosevelt Island via the Queensboro Bridge were unusable; and the only way on and off the island was via the Roosevelt Island Bridge to Queens. An aerial tram route, the Roosevelt Island Tramway, was opened in May 1976 as a "temporary" connection to Manhattan. The Roosevelt Island Operating Corporation was formed in 1984 to develop the island, but was not successful until October 1989 when the subway station opened along with the rest of the 63rd Street Line. After that, a high-rise luxury apartment building with some subsidized housing opened. The project faced extensive delays. As early as 1976, the Program for Action had been reduced to seven stations on the Archer Avenue and 63rd Street lines and was not projected to be complete for another decade. By October 1980, officials considered stopping construction on the 63rd Street line. The MTA voted in 1984 to connect the Queens end of the tunnel to the local tracks of the IND Queens Boulevard Line
