The Hutchinson River Parkway (known colloquially as The Hutch) is a north–south parkway in southern New York in the United States. It extends for 18.71 miles (30.11 km) from the massive Bruckner Interchange in the Throggs Neck section of the Bronx to the New York–Connecticut state line at Rye Brook. The parkway continues south from the Bruckner Interchange as the Whitestone Expressway (Interstate 678) and north into Greenwich, Connecticut, as the Merritt Parkway (Connecticut Route 15). The roadway is named for the Hutchinson River, a 10-mile-long (16 km) stream in southern Westchester County that the road follows alongside. The river, in turn, was named for English colonial religious leader Anne Hutchinson.
