The Kill Van Kull is a tidal strait between Staten Island, New York and Bayonne, New Jersey in the United States. It is approximately 3 miles (4.8 km) long and 1,000 feet (305 m) wide and connects Newark Bay with Upper New York Bay. The Robbins Reef Light is at the eastern end of the Kill, and Bergen Point marks its western end. It is spanned by the Bayonne Bridge and is one of the most heavily traveled waterways in the Port of New York and New Jersey.
