Original: The Long Island Expressway (Interstate 495) runs from the Queens Midtown Tunnel on the west through the borough to Nassau County on the east. The Grand Central Parkway, whose western terminus is the Robert F. Kennedy Bridge, extends east to the Queens\/Nassau border, where its name changes to the Northern State Parkway.
Simplified: Important state highways in Queens include the Grand Central Parkway, which becomes the Northern State Parkway when it crosses the Queens border into Nassau County.
