New York State Route 25A is a New York State highway and the main East-West route for most of the North Shore of Long Island, running from the Queens Midtown Tunnel in the New York City borough of Queens at its western terminus to Calverton in Suffolk County at its eastern end.
Known for its scenic route through decidedly lesser-developed areas such as Brookville, Fort Salonga, and the Roslyn Viaduct, 25A begins as 21st Street in Long Island City. As you go farther through 25A, it is then known as Jackson Avenue for a short period and is variously named Northern Boulevard east of Queens Plaza (New York State Route 25), North Hempstead Turnpike, Main Street, Fort Salonga Road, and North Country Road. It merges with New York State Route 25 for approximately 1.5 miles in Smithtown.
