NY 27 runs along southern Long Island, from Brooklyn to Montauk Point. It has two freeway segments, the Prospect Expressway and Sunrise Highway. The Sunrise Highway was planned to extend to the west as an elevated freeway across Nassau County and to the east past Amagansett. Bost proposals were cancelled.
