New York State Route 25A (NY 25A) is a state highway on Long Island in New York, United States. It serves as the main east–west route for most of the North Shore of Long Island, running for from Interstate 495 (I-495) at the Queens–Midtown Tunnel in the New York City borough of Queens to NY 25 in Calverton, Suffolk County. The highway is a northern alternate route of NY 25, which follows a more inland routing along Jericho Turnpike. The route is known for its scenic path through decidedly lesser-developed areas such as Brookville, Fort Salonga, Centerport, and the Roslyn Viaduct. It is known by various names along its routing, the most prominent of which include Northern Boulevard, North Hempstead Turnpike, Main Street, Fort Salonga Road, and North Country Road. It merges with NY 25 for approximately in Smithtown. Route description Queens NY 25A begins at I-495 exit 14—the second exit off the expressway—in Long Island City in the New York City borough of Queens. The route initially heads northward, following 21st Street for three blocks before turning northeast onto Jackson Avenue. Here, NY 25A widens from two to four lanes, a width that the road retains well into Nassau County. The highway serves the Long Island City Courthouse on its way to a junction with Queens Boulevard (NY 25) at the foot of the Queensboro Bridge. Here, the road changes names again, becoming Northern Boulevard. Unlike the first two names, the Northern Boulevard name extends for a considerable distance, remaining with NY 25A through the neighborhoods of Long Island City, Woodside, Jackson Heights, Corona, East Elmhurst, Flushing, Bayside, Douglaston and Little Neck. Northern Boulevard is the starting point of several prominent streets, such as Springfield Boulevard, Steinway Street, Roosevelt Avenue and Woodside Avenue. As Northern Boulevard, NY 25A begins to follow a more easterly path, loosely paralleling the Sunnyside Yard to the south. NY 25A continues east into Woodside, and the Brooklyn–Queens Expressway (I-278) intersects with Northern Boulevard at the Woodside–Jackson Heights border. Northern Boulevard serves as the southern border for East Elmhurst from the Brooklyn-Queens Expressway to 114th Street. It also serves as the northern border for Jackson Heights and North Corona. NY 25A becomes a part of a large street grid and running along a linear alignment through Jackson Heights, Corona, and East Elmhurst.
