New York State Route 218 (NY 218) is a state highway located within Orange County, New York, in the United States. It loops off U.S. Route 9W to run closer to the Hudson River between Highland Falls and Cornwall-on-Hudson. North of Highland Falls, it is briefly concurrent with US 9W.

U.S. Route 9W (US 9W) is a north–south United States Numbered Highway in the states of New Jersey and New York. It begins in Fort Lee, New Jersey, as Fletcher Avenue crosses the US 1/9, US 46, and Interstate 95 (I-95) approaches to the George Washington Bridge, and heads north up the west side of the Hudson River to US 9 in Albany, New York. As its "W" suffix indicates, US 9W is a westerly alternate route of US 9 between the two locations. US 9W directly serves three cities—Newburgh, Kingston, and Albany—and enters the vicinity of several others. As the route heads north, it connects to several highways of regional importance, including I-84, US 209, New York State Route 23 (NY 23), and US 20. Much of US 9W parallels the New York State Thruway and NY 32; additionally, the latter overlaps with US 9W in four different locations.
