Interstate 684 actually begins as two separate spur routes. The primary spur (the one officially designated I-684) begins at the White Plains/Harrison line at Exit 9A of the Cross-Westchester Expressway (Interstate 287). The other (designated New York State Reference Route 984J but still signed I-684) begins in Harrison, New York at exit 26A of the Hutchinson River Parkway and has one independent exit before joining with the I-287 spur into one route. The route follows a northerly course near the New York/Connecticut border, passing the Westchester County Airport, and at one point actually crossing the northwest corner of the Connecticut panhandle for 1.4 miles (2.3 km) without any exits before returning to New York (this brief interstate section is maintained by the New York State Department of Transportation but owned by the Connecticut Department of Transportation). Towards the northern border of Westchester County, it meets the northern terminus of the Saw Mill River Parkway. Once crossing into Putnam County, I-684 interchanges with its parent Interstate 84 in Brewster (map) before making a final interchange at a concurrency of U.S. Route 6, U.S. Route 202, and New York State Route 22, at which point the route terminates and becomes part of New York State Route 22. The speed limit is 65 mph (105 km/h), except on the spur from the Hutchinson River Parkway to just north of the Interstate 287 merge, and just south of the Interstate 84 terminus.
The route of the New York section of Interstate 684 is defined as part of Interstate Route 502 in New York Highway Law § 340-a.[1]

The alignment of I-684 is part of the original routing of Interstate 87. The designation was changed in 1970 when it was decided to have I-87 go along the New York State Thruway and, north of Albany, the Adirondack Northway.
