[1][2][3][4] The highway would have featured a total of 10 lanes, and had an estimated price tag of $40,000,000 (equivalent to $377 million in 2023[5]).
[2][6][7] This led to the Freeport–Roslyn Expressway proposal being postponed by Nassau County c. March 1952, and ultimately being cancelled that October.
[8][9][10][11] The section of the expressway between Freeport and Baldwin would have been located parallel (and adjacent) to Milburn Creek.
[7] The middle segment would have brought the expressway through the heart of Nassau County, providing access to places such as Hempstead, Garden City, Roosevelt Field, and Mineola.
[7][12] The northern segment would have followed (or paralleled) the alignment of Glen Cove Road, connecting to the Long Island Expressway (its parent route) in East Hills, in the vicinity of Roslyn.
