Entrance to the IND subway station at West 4th Street, near Washington
Square in Greenwich Village, Manhattan, New York City, April 23, 2018.
"Everybody knows" that (at least) parts of the D line, including many of its
stations, were New Deal projects. But I so far I have not been able to find
a definitive reference. Living New Deal says of this station (as it does of
many other stations on this line), "The Sixth Avenue branch trunk line of
New York City's Independent Subway (IND) was constructed during the 1930s
with the aid of federal Public Works Administration (PWA) funds. On December
15, 1940, six additional IND subway stations opened along Sixth Avenue. The
West Fourth Street — Washington Square subway station was one of the
six to open at this time." I'll leave it that for now.

support of the IND subway lines, but still nothing definitive.
