United States Route 4 is a United States highway that runs from Portsmouth, New Hampshire to East Greenbush, New York. In New Hampshire and Vermont it runs generally east-west; in New York, north-south. Signage changes from "East/West" to "North/South" at the Vermont/New York state line. It is known as "the Great River Road."
Before being designated as US 4, the road from Whitehall, New York eastward through Vermont was known as New England Interstate Route 13 (NE-13). From the Vermont-New Hampshire state line to Franklin, New Hampshire, it was the eastern end of NE-14. From Franklin to Concord, New Hampshire it used NE-6 (now US 3), and from Concord to Northwood, New Hampshire it used NE-9 (now NH-9). Between Northwood and Dover, New Hampshire, it used a road that was previously not numbered. From Dover to its eastern terminus at Portsmouth, New Hampshire, the road used to be known as NE-16 (now NH-16).
