Round Swamp Road

Begins at the Bethpage State Park's southern side and runs north to the Long Island Expressway, and ends in Suffolk County at Jericho Turnpike in West Hills. It was named for the swamp on Huntington's western boundary by settlers and Messtopass, meaning "a filthy pool of water" by the Native Americans.
