Subway expansion in New York

In the mid-1960s, $600,000,000 was made available to the Metropolitan Transit Authority (MTA)[?] of New York City for the purposes of subway expansion. $1,230,000,000 was spent to create three tunnels and a half-dozen holes. Construction would cease in 1975 on account of the city's severe fiscal crisis. None of the sections were usable by the time federal payments were suspended in 1985.
