Hylan Boulevard is a major northeast-southwest boulevard in the New York City borough of Staten Island. It is approximately 14 miles (23 km) long, and runs from the North Shore neighborhood of Rosebank to the South Shore neighborhood of Tottenville. It was renamed in 1923 for New York City mayor John F. Hylan, before which it was known as Pennsylvania Avenue. It is often misunderstood to be read as Hyland or Highland Boulevard.
