Construction on the Sixth Avenue extension at Bedford Street, 1928. The six-story buildings at left are 174-178 West Houston Street (although the entrances are actually on Bedford).

Until 1925, Sixth Avenue extended only as far South as Carmine Street. As it had done for the 1917 Seventh Avenue extension, the city used eminent domain to clear existing structures between Carmine and Canal Streets— including the entirety of the forgotten Hanover, Congress, and Clark Streets — to make way for construction of the IND Eighth Avenue subway under the new Sixth Avenue extension. The new Eighth Avenue line opened in September 1932, seven years after work began on the extension aboveground.
