A detailed guide map of Manhattan, extending north onto the mainland to Yonkers and Mount Vernon, west to the New Jersey shoreline from Hoboken to Fort Lee and beyond, and east to Long Island and Riker's Island. Icons such as Brooklyn Bridge (1883), Manhattan Bridge (under construction since 1901, but not open to traffic until 31 December 1909), Grand Central Terminal (rebuilt between 1903 and 1913), the new subway and elevated railways are shown. In 1909 New York and New Jersey celebrated the 300th anniversary of Henry Hudson's discovery of the Hudson River, and the centenary of Robert Fulton's first successful commercial paddle-steamer service, with an elaborate commemoration, the Hudson-Fulton Celebration. The first decade of the twentieth century was one of exponential development and growth for lower Manhattan in particular, which peaked in 1910. Thereafter, the availability of the outer boroughs and suburbs, to companies such as the A-RE-CO, made possible by improved transport links emphasised in this map, diffused population density and spread the reach of private and commercial development.
