It serves as the main east–west route for most of the North Shore of Long Island, running for 73 mi 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.

Steinway Tunnel The Steinway Tunnel carries the trains of the New York City Subway under the East River between 42nd Street in Manhattan and 51st Avenue in Long Island City, Queens, in New York City. It was originally designed and built as an interurban trolley tunnel (hence the narrow loading gauge and height), with stations near the current Hunters Point Avenue and Grand Central stations of the trains . It is named for William Steinway, who was a major promoter of its construction, although he died in 1896 before it was completed.
