U.S. Route 281
U.S. Numbered Highway in the United States
U.S. Route 281 (US 281) is a north–south United States Numbered Highway. At 1,875 miles (3,018 km) it is the longest continuous three-digit U.S. Route.
The highway's northern terminus is at the International Peace Garden, north of Dunseith, North Dakota, at the Canadian border, where it continues as Highway 10. The route between Dunseith and the border is shared with North Dakota Highway 3. US 281 has two southern termini. The western terminus, known as International Boulevard in Hidalgo, begins from the McAllen–Hidalgo International Bridge. The southern eastern terminus of US 281 is in Brownsville, Texas, just short of the Mexican border ending on Bus. 77. The two spurs come together at South Cage Boulevard in Las Milpas, Texas going north into Pharr, Texas. Thus, US 281 is the only continuous three-digit US route to extend from the Canadian border to the Mexican border.
