U.S. Route 4 (US 4) is a United States Numbered Highway that runs from East Greenbush, New York, in the west to Portsmouth, New Hampshire, in the east, traversing Vermont. In New York, US 4 is signed north–south to reflect its alignment in the state. In Vermont and New Hampshire, the route is signed east–west, the conventional direction for even-numbered U.S. Routes. Route description |- |NY | |- |VT | |- |NH | |- |Total | |} New York In the state of New York, US 4 begins at the concurrency of US 9 and US 20 in East Greenbush. Heading northward, it has an interchange with Interstate 90 (I-90), continuing northward into Troy. In Troy, it passes by Hudson Valley Community College as well as the headquarters of the 42nd Infantry Division. US 4 then heads downhill, passing the historic South End Tavern as Burden Avenue, named for the historic Burden Iron Works. Later, US 4 assumes Fourth Street, which splits into parallel one-way streets (Third Street handles southbound traffic). Once through Troy's historic downtown, the streets meet and pass by the Green Island Bridge, later passing under the Collar City Bridge and into Lansingburgh. After Lansingburgh, US 4 turns left to cross the Hudson River on the Troy–Waterford Bridge, entering Waterford, joining with New York State Route 32 (NY 32) to head north together west of the Hudson. After Mechanicville, US 4 and NY 32 split, and US 4 passes by the Battles of Saratoga and Gerald B. H. Solomon Saratoga National Cemetery. NY 32 joins again to pass through Schuylerville, after which US 4 splits off to cross the Hudson River one last time. Running parallel to the Champlain Canal, US 4 passes through villages including Fort Edward, Hudson Falls, Fort Ann, and Whitehall. After a concurrency with NY 22, US 4 heads eastward into Vermont. Vermont In the state of Vermont, US 4 immediately becomes a four-lane divided expressway. The historic routing of US 4 runs nearby as Vermont Route 4A (VT 4A), which later becomes US 4 Business as it enters Rutland. South of Rutland, US 4 meets US 7 and overlaps it into downtown, meeting the east end of its business route. East of Rutland, US 4 is a two-lane highway, meandering through the Green Mountains, passing by Killington, going through Woodstock and Quechee, crossing the Quechee Gorge, and meeting US 5, I-89, and
