I684
I684 is a designation that can refer to several different entities, making context crucial for precise identification. Most commonly, it is associated with a highway route. For instance, Interstate 684 is a spur route of Interstate 84 located in the U.S. states of New York and Connecticut. It runs for approximately 32 miles, connecting the town of North Castle, New York, to Brewster, New York, and then extending into Connecticut, where it terminates at its parent route, I-84. This interstate is a significant artery for traffic traveling between Westchester County, New York, and points further north and east.
In other contexts, I684 might be a catalog number or identifier within a specific system or database.
