 The project encountered difficulties, including the presence of oyster beds in the boulevard's path, which had to be removed before construction could proceed.Referred to as Jamaica Bay Boulevard, the southern portion between Broad Channel and Rockaway Beach opened in October 1924, and the entire route up to the existing intersection of Woodhaven Avenue and Liberty Avenue opened a year later in 1925.The new boulevard used much of Flynn's original right-of-way, but the causeway across Jamaica Bay connected to mainland Queens east of the location of Flynn's plateau.
