Interstate 684 constitutes a commuter freeway linking I-84 in Putnam County with I-287 (Cross Westchester Expressway) at White Plains and Hutchinson River Parkway south toward New York City. Traveling 29 miles, I-684 runs north from Purchase to Rye Lake. Between NY 120 (Exit 2) and NY 22 (Exit 3), I-684 passes through portion of Greenwich, Connecticut, though without any local access. Northward, I-684 traverses timberland and suburban areas through the towns of Bedford, Somers and Southeast.
