4. Randalls Island and Wards Island

Randalls Island and Wards Island were also separate islands, connected via landfill by Robert Moses. The 103rd Street Footbridge, which connects the island to Manhattan can be lifted in the center to allow ships to pass. Randalls Island is now home to Icahn Stadium and many sports venues. There’s also a new bridge, the Randall’s Island Connector that connects to the South Bronx from the northern end the island.
