From the 1920s to the 1940s, Long Island began the transformation from backwoods and farms as developers created numerous suburbs. Numerous branches of the Long Island Rail Road (LIRR) already enabled commuting from the suburbs to Manhattan. Robert Moses engineered various automobile parkway projects to span the island, and developed beaches and state parks for the enjoyment of residents and visitors from the city. Gradually, development also followed these parkways, with various communities springing up along the more traveled routes.
