In 1936, the islands were connected to the rest of the city by the Triborough Bridge, the hub of which crossed the islands. The American Society of Civil Engineers designated the Triborough Bridge Project as a National Historic Civil Engineering Landmark in 1986. On November 19, 2008, the Triborough Bridge was officially renamed after Robert F. Kennedy at the request of the Kennedy family. To manage the bridge (and eventually all tolled New York City water crossings), the Triborough Bridge and Tunnel Authority erected an art deco head building, the former base of Robert Moses; the building still stands on the island.
